This was the first clear and succinct explanation I've encountered for why oxy and acetylene are used together. Now it makes a lot more sense. Thank you for this - finally my more basic questions are answered. : )
Hi Dave thanks for a great video. You explained everything nicely so anyone could understand. I've been silversmith in for 15 yrs but am just now trying out the little torch. I'm excited so I'm here learning how to use it safely. Thanks again.
Just a small safety point. But many people have comment that you shouldn't use standard PTFE tape on gas connectors. They shouldn't need anything at all. Worth acknowledging. Dave.
The torch arrived today, and after careful assembly and checking for leaks, I put it through some basic soldering tasks...and am very pleased with the results! In the past, I used a micro butane torch for all of my work, but this torch delivers a hotter and more precise flame that will be very useful for the detailed work I do. With refillable butane torches, one of the biggest complaints was how the temperature dropped off midway through my soldering tasks, forcing me to stop and refill the gas. Of course, with an oxygen torch it's always hot, and the large-capacity oxy/propane tanks mean a more consistent flame over a day's work and more consistent solder joints. Thanks Dave for the recommendation! I trust your product reviews, because I get excellent results with these tools.
Thanks, I was contemplating purchase of one for jewelry use. Looks just like what I needed. I like to see people using things rather than just ordering and hoping for the best, your providing a real service. Thanks again.
Thanks. Do note the many comments though about not using tape on the gas threads. Note too I have also made a video on the oxygen generator and on the multi jet nozzle for this torch. see below.

Excellent demonstration. I have several students that are owners of this torch, but have yet to light them! This may be just the ticket to getting them up and running! :)
Jean pSmith Thanks, Once set up you don't have to worry about it. It's a great little torch, as you will see on many of my videos. the precisions is great for my work. I use it in the "how to solder" video. Thanks for the kind words. Dave.
That's awesome Dave, I don't have that much bird sounds around me living in more of a city location of Southern California USA but suburban enough that every once in a while they come in and when I hear them all singing, I do the same thing...I stop working, sit down on a lounge chair, have a cup of tea and just take it all in. Something so satisfying with it. I think I need to go buy some bird feeders today to help draw more in more often :) Awesome clip with the bird bud and keep up the great vids.
Hi Guys, just a little safety point.... BOC (British oxygen company) Do not recommend the use of "standard" ptfe tape on the "oxygen" lines. "Standard PTFE tape contains oil; oxygen reacts violently with oil and may spontaneously burn with an explosive force. BOC does not recommend the use of PTFE or other thread sealing components in conjunction with any gas cylinder valves or regulators." www.boconline.co.uk Whilst I've never heard of anyone blowing themselves up with a roll of ptfe tape, it would be remiss of me not to pass on this official guidance. I believe you can get green ptfe tape which has no oil in it (suitable for oxygen). As far as I know quality PTFE gas tape white or yellow, should be fine with the propane if you do need it. (unless someone has evidence to the contrary). But if your connectors are correctly fitting and in sound condition, then you shouldn't really need anything at all. Vice versa, if your connectors are leaking then there's something wrong, so replace them accordingly. Also the soapy water trick, to check for leaks was actually told to me by a plumber. Obviously it works, but is a bit of a no-no from professional gas people, again for the above reason of oils in the soap. Its a small point, but the recommended solutions are "Snoop" or "Teepol " to check for leaks. Ask your local welding supplier if you are unsure. Thanks for watching ! Take care guys. Dave.
Very helpful as I make a difficult decision on the purchase of my first torch! Thank you :) Also, your accent is adorable :) Made it even more fun to watch. Thank you thank you!
@@CelticDreamsCoUk : yeah, I saw those posts on the tape, what's the deal with the tape? Does it cause an explosion? Or is it a mini welder purist ideology? Like never go beyond the minimum.
The theory is, that the tape is made from plastic, which is made from oil and so under pressure could burst into flames. I admit it sounds crazy and I have never heard of anyone blowing themselves up with tape. But there you go, the official rule is you don't use tape on gas fittings. A more common sense reason is simply that you shouldn't need to. Gas fittings seal at the ends, not with the threads. So if there is a leak then the fitting is not properly attached or is perhaps damaged. If its not gas tight then there's a problem with the fitting. So I do agree with that. Thanks for watching. Dave
Hiya, your commentaters are spot on, the tread only holds the parts together and therefore use no tape!!! If on other types of connector the treads do provide the seal use P.T.F.E. tape from a yellow reel not blue, yellow is for gas, blue for water.Thank you for a good demo...
This is probably the top tool I need an upgrade. I'm currently using a butane micro-torch for soldering and a bigger one for annealing. No doubt, a small, very hot flame would save me some soldering trouble I'm experiencing. Great video and looks like the product I will probably buy to do this job. That I can run propane over a more wonky gas like acetylene is a plus too. Thanks!
great idea! If I can find a used oxygen generator...that will be a good long-term solution. For now, I got a cheap bottle of Oxygen at a welder's shop.
Thanks so much for your sharing Dave. I recently posted a question which you responded to but there was a broken link on the notification email back to the thread on UA-cam to where our conversation was happening. "Not sure what you mean by "rules". The normal soldering rules allays apply, clean, will fitting and well fluxed. If using 12ct yellow gold then you'd use the same solder 12ct yellow, either strip, wire or paste. Gold tends to heat up faster than silver does, so a little more care with the heat is needed. But apart from that its just the same. Just match the colour and carat of the solder to the metal you are using. Hope this helps. Dave" this was your reply. Thanks so much, this information is very useful 👍
Hello Dave, thanks for the video. I have bought one of these torches. I intend to use for for oxycetylene. I took it to a local gas supplier shop and he informed me that the connectors are American size (imperial) not metric (it clearly is as its an American company who made it) so aren't technically 'safe'. Seeing your vid has made me think I'll risk it though.
Mine just goes straight on to my regulators. I believe they make USA and UK versions with different threads. But either way, Just get an adopter if you need one. Dave.
+Frances Winyard .....Thanks Frances. I hope I inspire you to have a go and try new things. The biggest obstacle to many is simply fear. I was in that position too. So hopefully I have encouraged a few people to get stuck in. Dave ; )
I was thinking, straighten the red hose, straighten the red hose. Interesting video, not seen one on the smiths little torch before, so very useful. Thanks.
PTFE tape is only needed on pipe threads where the threads are your seal. With the type of connection that is on the lines, the threads aren't the seal. The threads only hold the tapered brass piece that is directly affixed on the gas lines. This is where it seals. Placing tape on the threads will only make is more difficult to tighten. It will do absolutely nothing to seal. If you have gas seeping at the threads check for nicks or debris on or between the brass piece on the hose and the inward taper that is at the end of the connection on the regulator. Fix it there not at the threads.
+David H Thanks David. That makes a lot of sense. Its not the threads that provide the gas seal, it's the end of the connector. A very useful insight. As jewellers we are simply end users of this equipment and information is very lacking. So thanks for that. Dave.
+David H Thanks for mentioning that, you saved me from having to mention it! It seems to me that most people who don't really know what they are doing with plumbing and gas fitting seem to think, "thread tape will fix it"... I have peeled kilometers of the stuff from threads in inappropriate applications where some inexperienced person has made the leak worse by thinking ,"thread tape will fix it".. Please people, inspect the design and principal of the union before applying tape.
on the other hand I have found many plumbing connections tightened so much that the pipes actually broke off in the fitting but had no sealant of any kind on the threads. Its just a matter of experience and having the right instruction.
Don't ever use pipe tape, it's a lubricant and not meant to seal. It's meant to assist tightening the tapered joint which is designed to be self sealing. Guess you never held a certificate of fitness from the fire department to operate torches legally. Even the booklet that accompanies a new set of torches states it!
In the States we use yellow PTFE tape for gas fuels. White tape is for water only. But, like the other person said, tape is not used for compression fittings.
Real nice and simple, so to speak...I have a hobby in silver jewelry and do some welding from time to time... And I would like to pick one up, to see if it will be helpful... What I have been using is my good old plumbing propane tank, not to mention the bulk it has, but work just the same, and so I needed to see just what this has to offer before I do buy it... You seem to have resolve it for me, so for that I thank you Sir....If there is any more info on this that you may have I will be happy to hear it...Thks again...JRC
I understand that the threads on the outlet of regulators for refilable cylinders differ from country to country. 3/8 x 19 tpi in the UK and 5/8 x 18 tpi in Australia. Regulators for disposable cylinders generally are 9/16 x 18 tpi. Some of the retailers of Smith little torches on ebay list the various thread types depeding on your desired setup.. All the best.
+labrat7357 Yes indeed, They do differ. An important point when buying gas equipment off the internet. It's important to match everything up. Thanks for your comments. Dave.
Jenny Näslund Thanks, this is exactly why I made it. many people want a torch, but don't understand what is involved. Do read my note about using the correct type of thread tape. Officially, There are different tapes for gas and oxygen. Glad you liked it. Many thanks of your feedback. Dave
★ I wish Petrogen would make a little torch like this. Petrogen torch uses regular pump gasoline and oxygen. I used to be a dealer and sold units to scrap yards. The torch tip stays cool to the touch, but it can cut better than anything on the market! 1 gallon of gasoline is equal to one large tank of acetylene.
Very helpful, thank you! I received this as a Christmas gift and the instructions really lacked in the different items I would need to get it set up to use.
I made the mistake of getting the kit without the regulators (currently $100 NZ each), it did come with the fittings for the disposable canisters but I've found, unless you don't need to do much, they're the expensive option (here $30 NZ for oxy if available and $45 NZ for propane). Yes buying 2 sets will equal the regulator price, the other problem here is nobody (unless your commercial) refill standard bottles and you can't own your own as the others work on an exchange program. I think even the smallest bottle would last me my lifetime for the amount I use. Thanks for the great review/tutorial.
Yes the small cans are expensive. Rent free bottles are the best option for most users.Paying for refills. But as you say, you need to find somewhere that does this, like a welding supplier. Thanks for watching, Dave
Oxygen regulator, and propane regulator. Ideally with gauges to help set the pressure and see when the tanks are empty. Oxygen are fairly easy to get, but most propane gauges are just for camping and bbq's. It's hard to find propane regulators with gauges. For this reason, myself, my colleagues in the trade, and everyone I have spoken to on forums "ALL" use acetylene regulators on their propane bottles. Im sure there are some purists who will say you shouldn't do that. But I haven't blown myself up yet, and they work fine. Hope this helps. Dave
Hi! Nice guide! What happens if you connect the gases in opposit order? Is the color of hoses only for indication? (I have a truble with the counterclockwise fitting on gas hose!!!)
It's not possible to connect the gas to the oxygen etc as they use different threads, one opposite to the other. They are made this way, for this reason so you can't connect them the wrong way round. Dave
Great video, you made it seem so simple. The problem I’m having is in sourcing the extras. I’m looking at conning...I mean persuading... my husband to buy me a Smiths Little Torch for my next 10 years-worth of birthdays. I’ve found the TB40 kit but the regulators and flashback arrestors are adding £100 on to the price. Is that normal, or can I get them from a DIY shop? Any pointers as to where? Hopeless and confused about the whole oxy-pro setup. If I didn’t hate the pathetic weakness of my Versaflame so much, I’d give up. Thanks!
The simple answer is wherever you get your oxygen and propane bottlers from, just ask them for a set of regulators. I get mine from my local welding supplier, along with Argon for my pulse welder. I just asked the guys to add the appropriate regulators. usually you will have to buy them, but some companies rent you the bottles pre fitted with the regulators too. So basically just look up your nearest welding suppliers, and they will be able to sort you out. Hope this helps. Dave
Thanks for the informative video, Dave. I wanted to ask, how many hours does the gas bottle and oxygen last, and what signs will you find when you need to refill/replace bottles? Thanks.
Difficult to say how long a bottle will last. When I’m soldering small chains, then I use a tiny flame, but casting uses a huge flame and a lot more oxygen and fuel. That said, my Smith’s little torch is extremely economical. When the oxygen is running out, it will go quickly. The flame will turn from a sharp blue point and start to go bushy and yellow, as the oxygen stops. I now use an oxygen concentrator, so don’t actually use the bottle any more, but I always keep a bottle just in case. I got about six months out of my first bottle with light use soldering every few days. Hope this helps. Dave
Tape works; Iv'e been doing the same for 50 years .Not all connectors are perfect and jewellers use very low pressure settings. If it passes the soapy water test then it is good to go.I would be more concerned with making sure the hoses are in good order.
Hello, I’ve been looking for an alternative torch to my sievert and mini propane versions. Your video was great thanks. One question is where to you get the oxygen tanks and how do you refil them please? 🙏
Here in the UK there is chain of suppliers called "Hobby weld" at various welding suppliers. you buy a cylinder and then just pay for refills (swaps). for the small home studio this is cheaper than paying contracts with big suppliers. There are other companies too that do this. Google your local welding suppliers. They should also be able to fix you up with regulators and flashback arrestors, mine did, all sorted in one shop. Hope this helps. Dave
So nearly a year on from using this torch, are you still happy using it? Are there any down sides to owning this torch in your year of experience with it? I am trying to decide between this torch with LPG or the German Precision Torch. Right now I am using an Orca with LPG, but am looking to upgrade. Thank you :)
+Little Cherry Hill - Metalsmith ....Great question Cherry. and yes indeed, I am happier than ever with it. Previously I had a British version of it, but that was very sensitive. the Smith's has far more control over the gas and 02 with a smooth action to the valves. As you may observe from my latest video (sixpence coin ring), I made the whole ring with hard solder. This could only be done with precise soldering and control of the heat. I don't think this would have been possible with any other torch. That said, you may also note my casting nozzle video, where I use the torch to melt 3 oz of silver in just a few minutes. There is a reason why it's such a popular torch - it's brilliant. you wont regret it. The Orca too is a great torch. But as at the start of my video, the little Orca is a gas and air so limited to tip size and temperature. The Smiths is a lot more versatile in its range of flame size, temp and control. Thanks for watching. Dave.
Just a point I was told, by a manufacturer, while researching torches and gas welding! You should never use an acetylene regulator with propane, the gauge which shows how much gas is left in the bottle does not work with liquid gases so is useless as it will read full for the whole time until it is empty then it will simply read empty which is why propane regulators only ever come with one gauge which shows the output pressure, but the most dangerous is the membrane which is inside the regulator which, if designed for acetylene, will deteriorate with propane causing leakage with is much more dangerous than acetylene as propane is heavier than air and will collect and sit causing a possible explosion when next igniting the torch!I just felt I should pass this info on to yourself as would not want anything bad to happen to you! I did however enjoy your video!
Thanks for that info and taking the time to share. The issue for jewellers is that it's almost impossible to find Propane regulators with gauges on. I guess most propane users are campers, Patio heaters and gas barbecues etc where the exact pressure doesn't need to be that precise. Professional welders tend to use acetylene. So i guess there isn't much of market for precise propane regulators as it's only really jewellers who use propane for fine soldering. hence why most jewellers I know use acetylene regulators on their propane tanks. it's really down to the suppliers who sell the torches. They should really sell an appropriate regulator i.e. with gauges (not available in the case of certain UK jewellery supplier). Thanks for the input. Dave.
Do you think It would be possible to use this torch only with butane? I don't know if It would be able to fuse silver without oxygen. And, if you think It is possible, would I have to put something at the end or the begining of the oxygen uptake?
The torch is designed for oxygen and fuel. It can use most fuels, with the correct hose adapter, such as propane, or acetylene. Not sure about butane. But either way, you still need oxygen. either bottled or from an oxygen concentrator. Dave
Hi! I hope you are fine... I finished setting up my acetylene/oxy torch, and I am struggling a bit with the lighting.... there is a lot of soot when I light the acetylene, and many times when I open the oxy, even a little, I get a small explosion at the tip and the flame goes out. Can you help me?
I've never used acetylene. Check the instructions and make sure you've got the pressure right on your regulators. Especially important with the smaller nozzles, too much pressure and they instantly blow themselves out as soon as you open the torch. So try backing them off a bit. Remember also to bleed to hoses if you haven't used them for a while. just open each tap on the torch for a few seconds before you light it, to flush out any air in the pipe. Hope this helps. Dave
Hi Dave, first of all, greeting from Malta Europe. I have bought the Smith Little Torch and waiting for delivery so then I buy the right regulators etc. I intend to use Protane+Oxygen as I need to braze little very thin steel .02mm (Tiny small job of 1 cm.) using either copper or bronze rods; do you think I can get the metal heated enough to do the job and melts the cooper or bronze rods ? Thanks in Advance; Sebastian.
In a word yes. Dont be fooled by the tiny size of the torch. It is still burning oxy propane and get to very high temperatures. If you are in any doubt check out my review of the large casting nozzle using oxygen and propane) Dave. ua-cam.com/video/uNTDAJXHY9U/v-deo.html
The torch simply supplies heat. So yes, any brazing or soldering. But be aware of the size here. Depending on what you are doing you may want something bigger, such as as the Sievert propane torch. Dave
Hi Dave, Thank for the demo. I hope you can help me, I've got this torch, but with disposable fuel (oxy and propane ) I can't get it ti light. I turn the fuel on the tanks then I purge it like you mentioned, then I turn the propane nozzle on and try to light it with a automatic torch lighter. It doesn't light, but there has been a few times it did light and I turn on the fuel for the oxy, right away it gets going and right away it goes out with a popping sound. Help! Thanks Jannet
+Jannet Douglass . Glad you got sorted. You should open the tanks fully. the flow is controlled by the regulators set to the appropriate pressure. You can then use the knobs on the torch to vary the flame size. allays start by purging the air out of both lines. Close both on the torch, then open the gas just a little, when lit you should get a small yellow flame. open open until it starts to blow itself out and back off a little. Slowly open the oxygen to get a blue flame. not too pointed for soldering, keep it "soft". Dave.
Butane is lighter gas. You can't really use it with the smiths torch. Some torches just use Propane, the smith uses propane and oxygen, this allows a smaller hotter flame. Dave
Can this torch be used with acetylene? It would be perfect when soldering thin copper lines like refrigerator sealed system when you also have a very limit space Thanks in advance Regards
+Nelson Agosto Yes the Smith little torch can be used with acetylene. But unless you are working with high temp platinum, theres little need. If you are working with copper then propane or butane are fine. And much easier to buy and use.
+Celtic Dreams awesome. thank you so much for your response. Im HVAC tech. and Im looking something smaller that I can use in tight space for example when Im soldering refrigerators sealed system, or replacing a compressor etc. Since I already have the tanks I only just need to swap this torch for the one I currently have installed. Regards
Hi, am having problems getting connecters to suit Smiths Torch to suit Mapp Gas bottles here in Australia, and do you really need gauges on bottles thanks Dave
+dave millar .. G' Day mate. Smith make a kit for connecting to the smaller bottles see the link below. This does give you some portability, but they will work out to be the most expensive way of fuelling your torch. In a workshop I'd say that yes, you really need the larger tanks and proper regulators. They will work out a "lot" cheaper and the adjustable gauges allow you to set the correct pressure for the different nozzles. Which is important. I'd suggest get in touch with a local welding supplier and get some propane and oxygen tanks with regulators. Once set up they will last years and cost almost nothing to run. Dave. www.smithequipment.com/files/pdf/spec_sheets/Little_Torch.pdf
No. normal air is mainly nitrogen which does not burn. So compressed air is of no use to the torch as it needs oxygen. You can however get oxygen generators, which is what I use. check out my video...Dave. ua-cam.com/video/M-3gHI8a1YY/v-deo.html
Dave I have just bought the sievert professional with the hope of delft casting. .....no luck! I can't get the sterling hot enough. I'm using the burner 3941 22mm general. I haven't used propane before so I am not sure if you open the canister control all the way. I'm afraid to keep turning it in case it comes off! ( I know, I'm not wise! ! ! ) HELP!
+Frances Winyard .... Hi Frances. The Sievert is a good torch - I have one myself as you see. It really depends on the nozzle you are using. Most jewellers use the needle flame attachment, which is great for soldering. But for melting and casting, you really need more heat. I have struggled myself, with propane or butane alone. This where the oxygen comes in, the addition of O2 produces a much hotter flame. OK, who things.... try a larger nozzle that burns more gas as a simple solution. But if you want to do a lot of casting then consider an Oxy propane torch. Also check out my video here... Dave. ua-cam.com/video/uNTDAJXHY9U/v-deo.html
I know it won't be the same but I was wondering, could this flashlight work with compressed air instead of oxygen? Use for small brazing, not for jewelry.
it needs pure oxygen, either bottles for from an oxygen concentrator (Oxy / fuel). An alternative is the Sievert professional torch kit (with a needle flame nozzle). This only uses propane, and utilises the oxygen in the air (Gas & air). So simpler and cheaper to run, but not quite the heat or fine flame as the smiths. Dave
The flash arrestor is completely not needed It takes an air fuel mixture of 2.5%-9.5% anything out side of that range is not flammable and will not burn, because the only thing in your tank is propane it is too rich to burn without introduce oxygen to it (Puncturing the tank or filling a tank with a mixture of propane and oxygen) Now acetylene on the other hand takes No oxygen at all to burn and there is a ton of tech in the bottle to keep it from self destruction a flash arrestor makes sense here.
True the propane is only dangerous when mixed with oxygen. So the chance of a flame tracking down the tiny propane line is somewhat doubtful. But I do feel safer having the arrestors just in case some bizzare disaster should ever occur. Thanks for the input. Appreciated. Dave
hi Dave. i just got myself a Little Smith from Cousins UK. which regulators should i get if using disposable/small tanks of fuel or am i better off with bigger tanks? i'll be using it indoors. TIA 🖤
Im not even sure you can get the smaller disposable tanks in the uk. But even if you can they are stupidly expensive and don't last long. Much better to get a small red propane cylinder. as used in barbecues and camping. DIY, shops, camping, even garages. You also need oxygen, for this youll need to find a local welding supplier. Search for "Hobbyweld", this is a chain of gas suppliers. No rental costs, just buy a cylinder and then pay for refill. For a modest user, its the cheapest way. I maybe go through just 1 or 2 a year. For regulators, you'll need standard British regulators (and flashback arrestors) for oxygen and propane, Available from most jewellery suppliers like cooksongold.com or just get them with you gas from your local welding supplier. Hope this helps. Dave
@@CelticDreamsCoUk hi Dave 🤓 many thanks for your detailed response. i was worried about having the bigger tanks/bottles in my home, where i work from & was going to get a 3.5 or 5kg one. i'm looking for a reconditioned oxygen concentrator. i have everything (torch, regulators & FBA's, magnetic stand) just waiting on getting fuel now. i'll look back on here in the new year. have a great festive season 🖤
Hi Dave, A very helpful video!! I notice that you are using an acetylene regulator with a propane tank, does this pose a problem? I am having trouble finding a propane regulator with a gauge. Thanks
Hi Gail, if you check out some of the other comments, this is frequent question. The problem is that propane regulators with gauges are hard to find and when you do they are expensive. If you think about it, the only people who want propane gauges are jewellers. Most people who use propane just use it for camping, caravans and gas barbecues, patio heaters etc, so don't need precise gauges. Likewise steel welders and auto garages, use oxy acetylene. So I guess the propane regulator market is a very limited one. Hence why most jewellers I know use acetylene regulators on their propane tanks. I'm sure some plumbers or gas experts would say that you shouldn't do that, but I don't know of anyone blowing themselves up, so far. So whilst I shouldn't officially recommend it, I can say that everyone I know does use acetylene reg's on their propane. They are readily available, have gauges and are cheap. I've never had a problem with mine. Hope this helps. Dave
Great informative video mate, any idea if the cheap Chinese knock offs are any good at all? I want that torch model but I'm just starting out and I have had to cut some budget areas to afford alot of the things I require and the torch is one area. I need a torch now and I'm going to buy the cheap ebay model of the little torch, I will upgrade to the real thing later if I sell some jewellery; hopefully
IF you need a budget model then just a get a butane chef's type torch. Perfectly suitable for small jewellery. if you want a larger version then look at a Sievert kit with a needle flame, this simply uses a propane bottle, fairly cheap and cheerful. Hope this helps. Dave
Shaun. You do get "cheap Chinese knock-offs" . I got one 3 years ago off ebay in a kit which included adjustable regulators and flame arrestors. I haven't had any trouble with it. I use it with acetylene because I inherited the bottles from my Dad. BTW : The ones on ebay with blue oxygen knobs are clones, the genuine article has a green oxygen knob.
For what? the oxygen regulators are readily available from any welding supplier. As for the propane, yes they are difficult to come by, as most propane users are for camping, DIY and barbecues. It's only really jewellers who need accurate propane regulators. You can get propane regs with gauges but they are ridiculously expensive. That said, I do what everyone else I know and have spoken to on forums does.... I use Acetylene regulators on the propane, which are readily available. Yes there will be internet experts out there who will shout that you cant do that, and some technical reason why not. But Ive always done this for years, as do my colleagues in the trade and people i have spoken to on forums. They work fine and I have blown anything up yet. hope this helps. Dave
@@CelticDreamsCoUk Hes talking about the Medical oxy bottle you are using. You will not be buying any compatible regulator from any shop you mention for that particular bottle
Hi Dave, glad I found your page. I am up a creek with trying to get the best fitting set up for what I'm trying to achieve, is the Acetylene and oxygen set up any different than propane? if do how does the initial set up differ? any help would be appreciated!
Either way the setup is the same. Oxygen bottle > oxygen regulator > flashback > torch Acetylene bottle> acetylene regulator > flashback > torch Ideally you'd have the flashbacks closer to the torch, but as the little torch hoses come pre attached, I connect them to the regulators. Its just an extra safety feature. I use propane, but as many jewellers do, I use an acetylene regulator which has two dials on it. One to show the tank full and one to adjust the pressure. Propane regulators with gauges seem to be very hard to find. Probably due to the limited market, as jewellers are the only ones who use propane for welding. But acetylene regulators are readily available. All jewellers I've spoken to, do the same. In my case i do not use any adaptors at all. the regulators go straight into the tanks and the flashback straight into the regulators , simple as that. Acetylene or propane is the same setup. I hope this makes sense. I'm not too sure that you're problem is. But your local welding supplier will be able to help in connecting anything up, or if you do need any adaptors. Dave.
Hello, thanks for your video, very useful. I would like to know which is the product code you've shown. Where can I buy the box with the torch (no gas tank.) Thank You Giovanni

Here is a link to the page www.cooksongold.com/Jewellery-Tools/Smith-Little-Torch-Kit-Oxy-Gas-----Fuels-Systems-prcode-999-7802 Of course I don't know what country you are in, but the Smiths little torch is available world wide, or order from Cooksons and get it posted. Its made in the USA www.smithequipment.com/ Thanks for watching. Dave.
I dont tend to work with steel, but I would have thought that Acetyline would be required for torch welding steel. Not really my area, but as far as i know TIG or mig is the usual method of welding steel. Hope this sort of answers your question. Dave
Greetings brother ; ) . Obviously I don't know where you are or even what country you are in. But just find your local welding suppliers. Every town will have them, as garages, building, construction, engineers etc. all use gas torches for welding. You'll need so source fuel and oxygen bottles, so the supplier should also be able to supply the regulators too. S & F Dave
Hi Dave, Thank you for the reply. Sorry I am in the East Midlands ( I forget this is the world wide web ) I have looked online to try get the regulators but cant seem to find them. S&F Rob

Its helpful to be able to see what pressure you are using, especially with the small nozzles. So its better to get a propane reg with gauges on. These are hard to come by, probably because only jewellers really propane to weld, so limited audience. For this reason most jewellers I know use Acetylene regs, on their propane tanks. obviously propane regs are much easier to get hold of. I'm sure someone would argue that's not right, but its served me well for many years. Check out Hobby weld (link below) its a national chain of gas suppliers, who sell bottles with no monthly rental. You pay a deposit and then just buy the gas. I get my argon (for my Orion pulse welder) from such a local supplier and they sorted out all the regs and adapters too. simple S & F Dave ; ) www.hobbyweld.co.uk/find-an-agent/
You can improve torch performance and keep the copper nozzles from heating too much by soldering short piece of vets hypodermic needle into the tip of the nozzle.
Not sure what you mean by "heating too much". The Smith nozzles have rubies in the tips which are drilled with lasers.They are very, very precise. You get a range of sizes in the kit and the torch is very controllable. So I'm not sure what you'd hope to achieve by adding a needle. The tips are perfect as they are. Dave.
@@CelticDreamsCoUk I've been a high end jeweller for over 50 years . I first tried this with the Phoenix torch as used by Cartier for many years ,so I thought I would try it with the Smiths .It works for me. Try it then tell me what you think , some of my jobs take hours to do ,resetting a flame every time you use it I don't think is a good idea .Regards Ed.
PTFE is probably not the way to go. Just clean the seats. sealing the thread with PTFE tape does not prevent gas from leaking from where the nut meets the hose. (I see others have already made notes about this)
Hi. I'm from Chile and I watch your videos. I can ask you a question. buy a SMITH LITTLE TORCH. and it comes with a detail on the propane hose. you can cut the hose and use the same connector ... I hope you can help me thank you .. from chile.
I'm not sure what your problem is exactly. But If you cant get adapters or the right size fittings, then yes. I guess you could cut the hoses or replace them completely, in order to connect them to your own fittings. I hope this makes sense, but do be more clear and I will try to help. Dave
@@CelticDreamsCoUk hola. gracias por la respuesta. mi ingles es malo yo hablo español... la pregunta es si se puede cortar la mangera roja de la conexion al propano y usar la misma abrazadera del conector ... no se como enviar una foto...la linea de propano se quebro antes de llegar al conector
+John McDermott Personally I haven't used a hydrogen / Oxygen torch but a friend has one. You get the very fine needle tips so great for fine work. I believe they can also be quite hot, so perhaps better for working with Platinum. The thought of having "free" fuel by just using water is a little bit of a myth though. With his, it needs special chemicals (acetone?) which are added to the water. And don't forget the cost of the electric too. So there are ongoing costs. But once set up, several people can use it at the same time and it takes up very little space. As I say, I haven't used one, but I believe the torches only have a single valve. The mix is set at the unit itself. So I'm not sure how flexible this makes it in operation. I like to vary the flame size and temp on the fly as I am working. I wouldn't want to start fiddling with the gas generator to do this. Ultimately it comes down to price and running costs. The smiths little torch is fairly cheap to buy and very cheap to run (for me). But a busy studio with several bench jewellers, may find the cost of gas and oxy gets expensive. Hence the high initial purchase price of a HHO gas generator is offset over time by the saving of not buying oxygen and gas tanks. Just my own thoughts, but hope this gives you something to think about and a starting point for more research. Dave.
Do not put Teflon tape on the threads. This will not prevent leaks and may make it worse. The seal is made between the male end of the brass barb and the female end of the brass fitting. A scratch on these surfaces will cause a leak.
This was the first clear and succinct explanation I've encountered for why oxy and acetylene are used together. Now it makes a lot more sense. Thank you for this - finally my more basic questions are answered. : )
I hope it helps you make a more informed decision. Thanks for watching. Dave
Hi Dave thanks for a great video. You explained everything nicely so anyone could understand. I've been silversmith in for 15 yrs but am just now trying out the little torch. I'm excited so I'm here learning how to use it safely. Thanks again.
Just a small safety point. But many people have comment that you shouldn't use standard PTFE tape on gas connectors. They shouldn't need anything at all. Worth acknowledging. Dave.
The torch arrived today, and after careful assembly and checking for leaks, I put it through some basic soldering tasks...and am very pleased with the results! In the past, I used a micro butane torch for all of my work, but this torch delivers a hotter and more precise flame that will be very useful for the detailed work I do. With refillable butane torches, one of the biggest complaints was how the temperature dropped off midway through my soldering tasks, forcing me to stop and refill the gas. Of course, with an oxygen torch it's always hot, and the large-capacity oxy/propane tanks mean a more consistent flame over a day's work and more consistent solder joints. Thanks Dave for the recommendation! I trust your product reviews, because I get excellent results with these tools.
The Smith's is a great torch. Do look at the casting nozzle a great addition. ! Dave. ua-cam.com/video/uNTDAJXHY9U/v-deo.html

nah, birds suck
Hi Guys, just a little safety point....
BOC (British oxygen company) Do not recommend the use of "standard" ptfe tape on the "oxygen" lines.
"Standard PTFE tape contains oil; oxygen reacts violently with oil and may spontaneously burn with an explosive force. BOC does not recommend the use of PTFE or other thread sealing components in conjunction with any gas cylinder valves or regulators." www.boconline.co.uk
Whilst I've never heard of anyone blowing themselves up with a roll of ptfe tape, it would be remiss of me not to pass on this official guidance.
I believe you can get green ptfe tape which has no oil in it (suitable for oxygen). As far as I know quality PTFE gas tape white or yellow, should be fine with the propane if you do need it. (unless someone has evidence to the contrary).
But if your connectors are correctly fitting and in sound condition, then you shouldn't really need anything at all. Vice versa, if your connectors are leaking then there's something wrong, so replace them accordingly.
Also the soapy water trick, to check for leaks was actually told to me by a plumber. Obviously it works, but is a bit of a no-no from professional gas people, again for the above reason of oils in the soap. Its a small point, but the recommended solutions are "Snoop" or "Teepol " to check for leaks.
Ask your local welding supplier if you are unsure.
Thanks for watching !
Take care guys. Dave.
...
Interesting about the soap. I was actually taught to spray soapy water in my welding classes, so it must not be too bad.

Very helpful as I make a difficult decision on the purchase of my first torch! Thank you :) Also, your accent is adorable :) Made it even more fun to watch. Thank you thank you!
Thank you! 😃 You must be in the USA, Americans seem to love my English accent. Thanks for watching. Dave
Hehe, not American. Canadian! In any case, excited as you helped me in my decision making.
Thanks for posting the video, I've got a few small projects and just got a mini, it's good starter video and just exactly what I needed.
Thanks. glad to have helped. But do note the many comments though about NOT using PTFE tape on the gas connectors. Dave
@@CelticDreamsCoUk : yeah, I saw those posts on the tape, what's the deal with the tape? Does it cause an explosion? Or is it a mini welder purist ideology? Like never go beyond the minimum.
The theory is, that the tape is made from plastic, which is made from oil and so under pressure could burst into flames. I admit it sounds crazy and I have never heard of anyone blowing themselves up with tape. But there you go, the official rule is you don't use tape on gas fittings. A more common sense reason is simply that you shouldn't need to. Gas fittings seal at the ends, not with the threads. So if there is a leak then the fitting is not properly attached or is perhaps damaged. If its not gas tight then there's a problem with the fitting. So I do agree with that. Thanks for watching. Dave
Hiya, your commentaters are spot on, the tread only holds the parts together and therefore use no tape!!! If on other types of connector the treads do provide the seal use P.T.F.E. tape from a yellow reel not blue, yellow is for gas, blue for water.Thank you for a good demo...
Thanks for watching.Dave
This is probably the top tool I need an upgrade. I'm currently using a butane micro-torch for soldering and a bigger one for annealing. No doubt, a small, very hot flame would save me some soldering trouble I'm experiencing. Great video and looks like the product I will probably buy to do this job. That I can run propane over a more wonky gas like acetylene is a plus too. Thanks!
I use the casting nozzle for annealing. I currently run the torch with an Oxygen generator. So very cheap to run. Dave
great idea! If I can find a used oxygen generator...that will be a good long-term solution. For now, I got a cheap bottle of Oxygen at a welder's shop.
Nice. I used one of these torches decades ago working with a silversmith in NYC. Time for me to get one. Thanks, and I subscribed, USA!
Thanks for the sub! and thanks for watching. Dave
Thanks so much for your sharing Dave. I recently posted a question which you responded to but there was a broken link on the notification email back to the thread on UA-cam to where our conversation was happening. "Not sure what you mean by "rules". The normal soldering rules allays apply, clean, will fitting and well fluxed. If using 12ct yellow gold then you'd use the same solder 12ct yellow, either strip, wire or paste. Gold tends to heat up faster than silver does, so a little more care with the heat is needed. But apart from that its just the same. Just match the colour and carat of the solder to the metal you are using. Hope this helps. Dave" this was your reply. Thanks so much, this information is very useful 👍
You're welcome. Dave.
Hello Dave, thanks for the video. I have bought one of these torches. I intend to use for for oxycetylene. I took it to a local gas supplier shop and he informed me that the connectors are American size (imperial) not metric (it clearly is as its an American company who made it) so aren't technically 'safe'. Seeing your vid has made me think I'll risk it though.
Mine just goes straight on to my regulators. I believe they make USA and UK versions with different threads. But either way, Just get an adopter if you need one. Dave.
Hi Dave, thanks for taking the time to make and post this :)

Thanks for watching.Dave
PTFE tape is only needed on pipe threads where the threads are your seal. With the type of connection that is on the lines, the threads aren't the seal. The threads only hold the tapered brass piece that is directly affixed on the gas lines. This is where it seals. Placing tape on the threads will only make is more difficult to tighten. It will do absolutely nothing to seal. If you have gas seeping at the threads check for nicks or debris on or between the brass piece on the hose and the inward taper that is at the end of the connection on the regulator. Fix it there not at the threads.
+David H
Thanks David. That makes a lot of sense. Its not the threads that provide the gas seal, it's the end of the connector. A very useful insight. As jewellers we are simply end users of this equipment and information is very lacking. So thanks for that. Dave.
+David H Thanks for mentioning that, you saved me from having to mention it! It seems to me that most people who don't really know what they are doing with plumbing and gas fitting seem to think, "thread tape will fix it"... I have peeled kilometers of the stuff from threads in inappropriate applications where some inexperienced person has made the leak worse by thinking ,"thread tape will fix it".. Please people, inspect the design and principal of the union before applying tape.
on the other hand I have found many plumbing connections tightened so much that the pipes actually broke off in the fitting but had no sealant of any kind on the threads. Its just a matter of experience and having the right instruction.
Don't ever use pipe tape, it's a lubricant and not meant to seal. It's meant to assist tightening the tapered joint which is designed to be self sealing. Guess you never held a certificate of fitness from the fire department to operate torches legally. Even the booklet that accompanies a new set of torches states it!
Very impressive presentation.
Kudos!
- Saskatchewan, Canada
Thank you very much! Dave
In the States we use yellow PTFE tape for gas fuels. White tape is for water only. But, like the other person said, tape is not used for compression fittings.
Correct. If you need tape, then your fittings have a problem. Dave
Real nice and simple, so to speak...I have a hobby in silver jewelry and do some welding from time to time... And I would like to pick one up, to see if it will be helpful... What I have been using is my good old plumbing propane tank, not to mention the bulk it has, but work just the same, and so I needed to see just what this has to offer before I do buy it... You seem to have resolve it for me, so for that I thank you Sir....If there is any more info on this that you may have I will be happy to hear it...Thks again...JRC
I hope you found the video helpful. Any questions just ask and I will try my best to help. Dave.
I understand that the threads on the outlet of regulators for refilable cylinders differ from country to country. 3/8 x 19 tpi in the UK and 5/8 x 18 tpi in Australia. Regulators for disposable cylinders generally are 9/16 x 18 tpi. Some of the retailers of Smith little torches on ebay list the various thread types depeding on your desired setup..
All the best.
+labrat7357 Yes indeed, They do differ. An important point when buying gas equipment off the internet. It's important to match everything up. Thanks for your comments. Dave.
Great review!
Many thanks. Best wishes Dave.
I haven't read through all the comments, but for the latecomers here's a fact. Any gas connection that has notched coupling nuts is >left-hand threads
Thanks for that, great tip look for the notches. Thanks Dave
Very helpful, this information was just what I was looking for, thanks so much!!
Jenny Näslund Thanks, this is exactly why I made it. many people want a torch, but don't understand what is involved. Do read my note about using the correct type of thread tape. Officially, There are different tapes for gas and oxygen.
Glad you liked it. Many thanks of your feedback. Dave
Bought one in 2005 and used it for doing refrigeration work. Great for "ultra low" temperature systems. Watchout for the import knockoffs.

★ I wish Petrogen would make a little torch like this. Petrogen torch uses regular pump gasoline and oxygen. I used to be a dealer and sold units to scrap yards. The torch tip stays cool to the touch, but it can cut better than anything on the market! 1 gallon of gasoline is equal to one large tank of acetylene.

Thanks for the comments. I'm glad you found it useful. I am also hoping to make a video on the large casting nozzle. Thanks for watching. Dave.
I made the mistake of getting the kit without the regulators (currently $100 NZ each), it did come with the fittings for the disposable canisters but I've found, unless you don't need to do much, they're the expensive option (here $30 NZ for oxy if available and $45 NZ for propane). Yes buying 2 sets will equal the regulator price, the other problem here is nobody (unless your commercial) refill standard bottles and you can't own your own as the others work on an exchange program. I think even the smallest bottle would last me my lifetime for the amount I use. Thanks for the great review/tutorial.
Yes the small cans are expensive. Rent free bottles are the best option for most users.Paying for refills. But as you say, you need to find somewhere that does this, like a welding supplier. Thanks for watching, Dave
Very informative, thanks
Thanks for watching. Dave
I like the video plus the sound of a beautiful bird behind the video👍👍
Thank you. check out this clip for a special guest appearance... Dave ua-cam.com/video/bf0DPhzy7S4/v-deo.html
Hi Dave, very informative thank you. But what type of regulator do I need to get for this type of set up.
Oxygen regulator, and propane regulator. Ideally with gauges to help set the pressure and see when the tanks are empty. Oxygen are fairly easy to get, but most propane gauges are just for camping and bbq's. It's hard to find propane regulators with gauges. For this reason, myself, my colleagues in the trade, and everyone I have spoken to on forums "ALL" use acetylene regulators on their propane bottles. Im sure there are some purists who will say you shouldn't do that. But I haven't blown myself up yet, and they work fine. Hope this helps. Dave
Hi! Nice guide! What happens if you connect the gases in opposit order? Is the color of hoses only for indication? (I have a truble with the counterclockwise fitting on gas hose!!!)
It's not possible to connect the gas to the oxygen etc as they use different threads, one opposite to the other. They are made this way, for this reason so you can't connect them the wrong way round. Dave
Great video, you made it seem so simple.
The problem I’m having is in sourcing the extras. I’m looking at conning...I mean persuading... my husband to buy me a Smiths Little Torch for my next 10 years-worth of birthdays. I’ve found the TB40 kit but the regulators and flashback arrestors are adding £100 on to the price. Is that normal, or can I get them from a DIY shop? Any pointers as to where? Hopeless and confused about the whole oxy-pro setup. If I didn’t hate the pathetic weakness of my Versaflame so much, I’d give up. Thanks!
The simple answer is wherever you get your oxygen and propane bottlers from, just ask them for a set of regulators. I get mine from my local welding supplier, along with Argon for my pulse welder. I just asked the guys to add the appropriate regulators. usually you will have to buy them, but some companies rent you the bottles pre fitted with the regulators too. So basically just look up your nearest welding suppliers, and they will be able to sort you out. Hope this helps. Dave
Thanks for the informative video, Dave. I wanted to ask, how many hours does the gas bottle and oxygen last, and what signs will you find when you need to refill/replace bottles? Thanks.
Difficult to say how long a bottle will last. When I’m soldering small chains, then I use a tiny flame, but casting uses a huge flame and a lot more oxygen and fuel. That said, my Smith’s little torch is extremely economical. When the oxygen is running out, it will go quickly. The flame will turn from a sharp blue point and start to go bushy and yellow, as the oxygen stops. I now use an oxygen concentrator, so don’t actually use the bottle any more, but I always keep a bottle just in case. I got about six months out of my first bottle with light use soldering every few days. Hope this helps. Dave
ah, okay. Six months is great. Thanks, Dave :)
Nice tool and vidéo.thanx for sharing
My pleasure. Thanks for watching. Dave
You’re knowledgeable person. Quite impressed!
Thank you, Very kind. Dave
No need for tape if your using proper gas fittings. It doesn't seal though the threads.
Quite correct, as some others have noted. Official guidance is not to use tape at all with gas lines. Thanks for watching. Dave.
Tape works; Iv'e been doing the same for 50 years .Not all connectors are perfect and jewellers use very low pressure settings. If it passes the soapy water test then it is good to go.I would be more concerned with making sure the hoses are in good order.
Hello, I’ve been looking for an alternative torch to my sievert and mini propane versions. Your video was great thanks. One question is where to you get the oxygen tanks and how do you refil them please? 🙏
Here in the UK there is chain of suppliers called "Hobby weld" at various welding suppliers. you buy a cylinder and then just pay for refills (swaps). for the small home studio this is cheaper than paying contracts with big suppliers. There are other companies too that do this. Google your local welding suppliers. They should also be able to fix you up with regulators and flashback arrestors, mine did, all sorted in one shop. Hope this helps. Dave
So nearly a year on from using this torch, are you still happy using it? Are there any down sides to owning this torch in your year of experience with it? I am trying to decide between this torch with LPG or the German Precision Torch. Right now I am using an Orca with LPG, but am looking to upgrade. Thank you :)
+Little Cherry Hill - Metalsmith ....Great question Cherry. and yes indeed, I am happier than ever with it. Previously I had a British version of it, but that was very sensitive. the Smith's has far more control over the gas and 02 with a smooth action to the valves. As you may observe from my latest video (sixpence coin ring), I made the whole ring with hard solder. This could only be done with precise soldering and control of the heat. I don't think this would have been possible with any other torch.
That said, you may also note my casting nozzle video, where I use the torch to melt 3 oz of silver in just a few minutes. There is a reason why it's such a popular torch - it's brilliant. you wont regret it.
The Orca too is a great torch. But as at the start of my video, the little Orca is a gas and air so limited to tip size and temperature. The Smiths is a lot more versatile in its range of flame size, temp and control.
Thanks for watching. Dave.
Helpful, thank you
Thanks for watching. Dave
Just a point I was told, by a manufacturer, while researching torches and gas welding! You should never use an acetylene regulator with propane, the gauge which shows how much gas is left in the bottle does not work with liquid gases so is useless as it will read full for the whole time until it is empty then it will simply read empty which is why propane regulators only ever come with one gauge which shows the output pressure, but the most dangerous is the membrane which is inside the regulator which, if designed for acetylene, will deteriorate with propane causing leakage with is much more dangerous than acetylene as propane is heavier than air and will collect and sit causing a possible explosion when next igniting the torch!I just felt I should pass this info on to yourself as would not want anything bad to happen to you! I did however enjoy your video!
Thanks for that info and taking the time to share. The issue for jewellers is that it's almost impossible to find Propane regulators with gauges on. I guess most propane users are campers, Patio heaters and gas barbecues etc where the exact pressure doesn't need to be that precise. Professional welders tend to use acetylene. So i guess there isn't much of market for precise propane regulators as it's only really jewellers who use propane for fine soldering. hence why most jewellers I know use acetylene regulators on their propane tanks. it's really down to the suppliers who sell the torches. They should really sell an appropriate regulator i.e. with gauges (not available in the case of certain UK jewellery supplier). Thanks for the input. Dave.

Do you think It would be possible to use this torch only with butane? I don't know if It would be able to fuse silver without oxygen.
And, if you think It is possible, would I have to put something at the end or the begining of the oxygen uptake?
The torch is designed for oxygen and fuel. It can use most fuels, with the correct hose adapter, such as propane, or acetylene. Not sure about butane. But either way, you still need oxygen. either bottled or from an oxygen concentrator. Dave
Hi Dave, Where do you purchase an oxygen talk?

I'm very much interested to buy this set
Thanks for watching. Dave
Hi! I hope you are fine... I finished setting up my acetylene/oxy torch, and I am struggling a bit with the lighting.... there is a lot of soot when I light the acetylene, and many times when I open the oxy, even a little, I get a small explosion at the tip and the flame goes out. Can you help me?
I've never used acetylene. Check the instructions and make sure you've got the pressure right on your regulators. Especially important with the smaller nozzles, too much pressure and they instantly blow themselves out as soon as you open the torch. So try backing them off a bit. Remember also to bleed to hoses if you haven't used them for a while. just open each tap on the torch for a few seconds before you light it, to flush out any air in the pipe. Hope this helps. Dave
Nice job 👍

next torch l buy. thanks
Thanks for watching. Dave
Hi Dave, first of all, greeting from Malta Europe. I have bought the Smith Little Torch and waiting for delivery so then I buy the right regulators etc. I intend to use Protane+Oxygen as I need to braze little very thin steel .02mm (Tiny small job of 1 cm.) using either copper or bronze rods; do you think I can get the metal heated enough to do the job and melts the cooper or bronze rods ? Thanks in Advance; Sebastian.
In a word yes. Dont be fooled by the tiny size of the torch. It is still burning oxy propane and get to very high temperatures. If you are in any doubt check out my review of the large casting nozzle using oxygen and propane) Dave.

Thank my friend; I've seen a lot of your work these last three days; that's why I asked you. (;
Hi dave can i use these for brazing with silicon bronze rod for fixing motorcycle and bicycle tubes
The torch simply supplies heat. So yes, any brazing or soldering. But be aware of the size here. Depending on what you are doing you may want something bigger, such as as the Sievert propane torch. Dave
Hi Dave,
Thank for the demo. I hope you can help me, I've got this torch, but with disposable fuel (oxy and propane ) I can't get it ti light. I turn the fuel on the tanks then I purge it like you mentioned, then I turn the propane nozzle on and try to light it with a automatic torch lighter. It doesn't light, but there has been a few times it did light and I turn on the fuel for the oxy, right away it gets going and right away it goes out with a popping sound. Help!
Thanks Jannet
+Jannet Douglass . Glad you got sorted. You should open the tanks fully. the flow is controlled by the regulators set to the appropriate pressure. You can then use the knobs on the torch to vary the flame size. allays start by purging the air out of both lines. Close both on the torch, then open the gas just a little, when lit you should get a small yellow flame. open open until it starts to blow itself out and back off a little. Slowly open the oxygen to get a blue flame. not too pointed for soldering, keep it "soft". Dave.
My set came with Propalene.. what’s the difference with this from Butane, Propane and Oxy?
Never seen it before
Thanks in advance
Butane is lighter gas. You can't really use it with the smiths torch. Some torches just use Propane, the smith uses propane and oxygen, this allows a smaller hotter flame. Dave
Спасибо за наглядный пример.
Спасибо за просмотр Dave
Can this torch be used with acetylene?
It would be perfect when soldering thin copper lines like refrigerator sealed system when you also have a very limit space
Thanks in advance

+Nelson Agosto Yes the Smith little torch can be used with acetylene. But unless you are working with high temp platinum, theres little need. If you are working with copper then propane or butane are fine. And much easier to buy and use.
+Celtic Dreams awesome. thank you so much for your response. Im HVAC tech. and Im looking something smaller that I can use in tight space for example when Im soldering refrigerators sealed system, or replacing a compressor etc.
Since I already have the tanks I only just need to swap this torch for the one I currently have installed.

Hi, am having problems getting connecters to suit Smiths Torch to suit Mapp Gas bottles here in Australia, and do you really need gauges on bottles
thanks Dave
+dave millar .. G' Day mate. Smith make a kit for connecting to the smaller bottles see the link below. This does give you some portability, but they will work out to be the most expensive way of fuelling your torch. In a workshop I'd say that yes, you really need the larger tanks and proper regulators. They will work out a "lot" cheaper and the adjustable gauges allow you to set the correct pressure for the different nozzles. Which is important. I'd suggest get in touch with a local welding supplier and get some propane and oxygen tanks with regulators. Once set up they will last years and cost almost nothing to run. Dave.

ok thanks dave
can an air compressor be used instead of an oxygen bottle that you buy in the store is there a difference?
No. normal air is mainly nitrogen which does not burn. So compressed air is of no use to the torch as it needs oxygen. You can however get oxygen generators, which is what I use. check out my video...Dave. ua-cam.com/video/M-3gHI8a1YY/v-deo.html
Great video thank u for being so thorough.
+Eklektyk Poppy You're welcome. Dave.
Dave I have just bought the sievert professional with the hope of delft casting. .....no luck! I can't get the sterling hot enough. I'm using the burner 3941 22mm general. I haven't used propane before so I am not sure if you open the canister control all the way. I'm afraid to keep turning it in case it comes off! ( I know, I'm not wise! ! ! ) HELP!
+Frances Winyard .... Hi Frances. The Sievert is a good torch - I have one myself as you see. It really depends on the nozzle you are using. Most jewellers use the needle flame attachment, which is great for soldering. But for melting and casting, you really need more heat. I have struggled myself, with propane or butane alone. This where the oxygen comes in, the addition of O2 produces a much hotter flame. OK, who things.... try a larger nozzle that burns more gas as a simple solution. But if you want to do a lot of casting then consider an Oxy propane torch. Also check out my video here... Dave.

I know it won't be the same but I was wondering, could this flashlight work with compressed air instead of oxygen? Use for small brazing, not for jewelry.
it needs pure oxygen, either bottles for from an oxygen concentrator (Oxy / fuel). An alternative is the Sievert professional torch kit (with a needle flame nozzle). This only uses propane, and utilises the oxygen in the air (Gas & air). So simpler and cheaper to run, but not quite the heat or fine flame as the smiths. Dave
@@CelticDreamsCoUk Thanks
The flash arrestor is completely not needed It takes an air fuel mixture of 2.5%-9.5% anything out side of that range is not flammable and will not burn, because the only thing in your tank is propane it is too rich to burn without introduce oxygen to it (Puncturing the tank or filling a tank with a mixture of propane and oxygen) Now acetylene on the other hand takes No oxygen at all to burn and there is a ton of tech in the bottle to keep it from self destruction a flash arrestor makes sense here.
True the propane is only dangerous when mixed with oxygen. So the chance of a flame tracking down the tiny propane line is somewhat doubtful. But I do feel safer having the arrestors just in case some bizzare disaster should ever occur. Thanks for the input. Appreciated. Dave
hi Dave. i just got myself a Little Smith from Cousins UK.
which regulators should i get if using disposable/small tanks of fuel or am i better off with bigger tanks? i'll be using it indoors. TIA 🖤
Im not even sure you can get the smaller disposable tanks in the uk. But even if you can they are stupidly expensive and don't last long. Much better to get a small red propane cylinder. as used in barbecues and camping. DIY, shops, camping, even garages. You also need oxygen, for this youll need to find a local welding supplier. Search for "Hobbyweld", this is a chain of gas suppliers. No rental costs, just buy a cylinder and then pay for refill. For a modest user, its the cheapest way. I maybe go through just 1 or 2 a year. For regulators, you'll need standard British regulators (and flashback arrestors) for oxygen and propane, Available from most jewellery suppliers like cooksongold.com or just get them with you gas from your local welding supplier. Hope this helps. Dave
@@CelticDreamsCoUk hi Dave 🤓 many thanks for your detailed response. i was worried about having the bigger tanks/bottles in my home, where i work from & was going to get a 3.5 or 5kg one. i'm looking for a reconditioned oxygen concentrator. i have everything (torch, regulators & FBA's, magnetic stand) just waiting on getting fuel now. i'll look back on here in the new year.
have a great festive season 🖤
Hi Dave, A very helpful video!! I notice that you are using an acetylene regulator with a propane tank, does this pose a problem? I am having trouble finding a propane regulator with a gauge. Thanks
Hi Gail, if you check out some of the other comments, this is frequent question. The problem is that propane regulators with gauges are hard to find and when you do they are expensive. If you think about it, the only people who want propane gauges are jewellers. Most people who use propane just use it for camping, caravans and gas barbecues, patio heaters etc, so don't need precise gauges. Likewise steel welders and auto garages, use oxy acetylene. So I guess the propane regulator market is a very limited one. Hence why most jewellers I know use acetylene regulators on their propane tanks. I'm sure some plumbers or gas experts would say that you shouldn't do that, but I don't know of anyone blowing themselves up, so far. So whilst I shouldn't officially recommend it, I can say that everyone I know does use acetylene reg's on their propane. They are readily available, have gauges and are cheap. I've never had a problem with mine. Hope this helps. Dave
Good job
Thank You. Dave
Great informative video mate, any idea if the cheap Chinese knock offs are any good at all? I want that torch model but I'm just starting out and I have had to cut some budget areas to afford alot of the things I require and the torch is one area. I need a torch now and I'm going to buy the cheap ebay model of the little torch, I will upgrade to the real thing later if I sell some jewellery; hopefully
IF you need a budget model then just a get a butane chef's type torch. Perfectly suitable for small jewellery. if you want a larger version then look at a Sievert kit with a needle flame, this simply uses a propane bottle, fairly cheap and cheerful. Hope this helps. Dave
Shaun.
You do get "cheap Chinese knock-offs" . I got one 3 years ago off ebay in a kit which included adjustable regulators and flame arrestors. I haven't had any trouble with it. I use it with acetylene because I inherited the bottles from my Dad.
BTW : The ones on ebay with blue oxygen knobs are clones, the genuine article has a green oxygen knob.
Hello, where did you find an adjustable regulator with such low outlet pressures ?
For what? the oxygen regulators are readily available from any welding supplier. As for the propane, yes they are difficult to come by, as most propane users are for camping, DIY and barbecues. It's only really jewellers who need accurate propane regulators. You can get propane regs with gauges but they are ridiculously expensive. That said, I do what everyone else I know and have spoken to on forums does.... I use Acetylene regulators on the propane, which are readily available. Yes there will be internet experts out there who will shout that you cant do that, and some technical reason why not. But Ive always done this for years, as do my colleagues in the trade and people i have spoken to on forums. They work fine and I have blown anything up yet. hope this helps. Dave
@@CelticDreamsCoUk Hes talking about the Medical oxy bottle you are using. You will not be buying any compatible regulator from any shop you mention for that particular bottle
Hi Dave, glad I found your page. I am up a creek with trying to get the best fitting set up for what I'm trying to achieve, is the Acetylene and oxygen set up any different than propane? if do how does the initial set up differ? any help would be appreciated!
Either way the setup is the same.
Oxygen bottle > oxygen regulator > flashback > torch
Acetylene bottle> acetylene regulator > flashback > torch
Ideally you'd have the flashbacks closer to the torch, but as the little torch hoses come pre attached, I connect them to the regulators. Its just an extra safety feature.
I use propane, but as many jewellers do, I use an acetylene regulator which has two dials on it. One to show the tank full and one to adjust the pressure. Propane regulators with gauges seem to be very hard to find. Probably due to the limited market, as jewellers are the only ones who use propane for welding. But acetylene regulators are readily available. All jewellers I've spoken to, do the same.
In my case i do not use any adaptors at all. the regulators go straight into the tanks and the flashback straight into the regulators , simple as that. Acetylene or propane is the same setup.
I hope this makes sense. I'm not too sure that you're problem is. But your local welding supplier will be able to help in connecting anything up, or if you do need any adaptors. Dave.
Celtic Dreams Thank you, I figured as much, but it never hurts to ask, but it might hurt not too!
Hello, thanks for your video, very useful. I would like to know which is the product code you've shown. Where can I buy the box with the torch (no gas tank.)
Thank You Giovanni
The product code is for www.cooksongold.com/ this is the UK company that supplied my torch. Here is a link to the page www.cooksongold.com/Jewellery-Tools/Smith-Little-Torch-Kit-Oxy-Gas-----Fuels-Systems-prcode-999-7802
Of course I don't know what country you are in, but the Smiths little torch is available world wide, or order from Cooksons and get it posted. Its made in the USA www.smithequipment.com/
Thanks for watching. Dave.
Celtic Dreams
Mille Grazie!!! from Italy
I got the answer to obtaining oxygen tank in the comments below. Thanks.
No problem. Dave
Can I use this torch to weld a nut on snapped or broken off steel bolt ?
I dont tend to work with steel, but I would have thought that Acetyline would be required for torch welding steel. Not really my area, but as far as i know TIG or mig is the usual method of welding steel. Hope this sort of answers your question. Dave
Hi Dave,
Im struggling to get a hold of the regulators & flash back arrestors for this torch.
Can you point me in the right direction.
S&F
Rob
Greetings brother ; ) . Obviously I don't know where you are or even what country you are in. But just find your local welding suppliers. Every town will have them, as garages, building, construction, engineers etc. all use gas torches for welding. You'll need so source fuel and oxygen bottles, so the supplier should also be able to supply the regulators too. S & F Dave
Hi Dave, Thank you for the reply. Sorry I am in the East Midlands ( I forget this is the world wide web )
I have looked online to try get the regulators but cant seem to find them.

Cooksons also supply propane regs, but they don't have gauges. Its helpful to be able to see what pressure you are using, especially with the small nozzles. So its better to get a propane reg with gauges on. These are hard to come by, probably because only jewellers really propane to weld, so limited audience. For this reason most jewellers I know use Acetylene regs, on their propane tanks. obviously propane regs are much easier to get hold of. I'm sure someone would argue that's not right, but its served me well for many years.
Check out Hobby weld (link below) its a national chain of gas suppliers, who sell bottles with no monthly rental. You pay a deposit and then just buy the gas. I get my argon (for my Orion pulse welder) from such a local supplier and they sorted out all the regs and adapters too. simple S & F Dave ; )

Thanks, great video. It was exactly I needed to know.
Glad it was helpful! Dave
You can improve torch performance and keep the copper nozzles from heating too much by soldering short piece of vets hypodermic needle into the tip of the nozzle.
Not sure what you mean by "heating too much". The Smith nozzles have rubies in the tips which are drilled with lasers.They are very, very precise. You get a range of sizes in the kit and the torch is very controllable. So I'm not sure what you'd hope to achieve by adding a needle. The tips are perfect as they are. Dave.
@@CelticDreamsCoUk I've been a high end jeweller for over 50 years . I first tried this with the Phoenix torch as used by Cartier for many years ,so I thought I would try it with the Smiths .It works for me. Try it then tell me what you think , some of my jobs take hours to do ,resetting a flame every time you use it I don't think is a good idea .Regards Ed.
PTFE is probably not the way to go. Just clean the seats. sealing the thread with PTFE tape does not prevent gas from leaking from where the nut meets the hose. (I see others have already made notes about this)
Yes indeed, You are absolutely correct. I intend to remake the video at some point (without ptfe). Thanks for watching. Dave
@@CelticDreamsCoUk I see others have already made the comment. Thank you for taking the time to reply anyway.
Is it possible to attach soldering tips for circuitry ?
No, that not what it made for, way too hot. Dave

Hi. I'm from Chile and I watch your videos. I can ask you a question. buy a SMITH LITTLE TORCH. and it comes with a detail on the propane hose. you can cut the hose and use the same connector ... I hope you can help me thank you .. from chile.
I'm not sure what your problem is exactly. But If you cant get adapters or the right size fittings, then yes. I guess you could cut the hoses or replace them completely, in order to connect them to your own fittings. I hope this makes sense, but do be more clear and I will try to help. Dave
@@CelticDreamsCoUk hola. gracias por la respuesta. mi ingles es malo yo hablo español... la pregunta es si se puede cortar la mangera roja de la conexion al propano y usar la misma abrazadera del conector ... no se como enviar una foto...la linea de propano se quebro antes de llegar al conector
What are your thoughts on HHO torches?
+John McDermott
Personally I haven't used a hydrogen / Oxygen torch but a friend has one. You get the very fine needle tips so great for fine work. I believe they can also be quite hot, so perhaps better for working with Platinum. The thought of having "free" fuel by just using water is a little bit of a myth though. With his, it needs special chemicals (acetone?) which are added to the water. And don't forget the cost of the electric too. So there are ongoing costs. But once set up, several people can use it at the same time and it takes up very little space. As I say, I haven't used one, but I believe the torches only have a single valve. The mix is set at the unit itself. So I'm not sure how flexible this makes it in operation. I like to vary the flame size and temp on the fly as I am working. I wouldn't want to start fiddling with the gas generator to do this.
Ultimately it comes down to price and running costs. The smiths little torch is fairly cheap to buy and very cheap to run (for me). But a busy studio with several bench jewellers, may find the cost of gas and oxy gets expensive. Hence the high initial purchase price of a HHO gas generator is offset over time by the saving of not buying oxygen and gas tanks.
Just my own thoughts, but hope this gives you something to think about and a starting point for more research. Dave.
En que plataforma me recomiendan comprarlo? Soy de Sudamérica.

Do not put Teflon tape on the threads. This will not prevent leaks and may make it worse. The seal is made between the male end of the brass barb and the female end of the brass fitting. A scratch on these surfaces will cause a leak.
Thanks, as many others have said. Dave.
