Very good video and outstanding choice of Smith (now owned by Miller) equipment. If someone lucks out and scores a concentrator with the pump for refilling medical oxygen cylinders they can do that too and have a very portable setup for demos or whatever. The Handi-Heet is also an excellent torch for joining copper pipe so you can repair and modify your plumbing for very little money if you're so inclined. Jewelry work is the most precise torch work. Compared to that ordinary torch soldering, brazing and gas welding are easy to learn.
Thanks for the comment! While the handi heat (smith silversmith) is a good torch, it doesn't get hot enough for many jewlery applications, the compressed oxygen plus propane is more suitable.
Thanks so much. I got hooked up with slightly different pieces but my concentrator alarm keeps going off. I have the same one as you it's the "!" Alarm. Have you had that happen?
eppa2277 The alarm is a warning that you have to open the valve on your torch to let the oxygen escapes! when the machine is on you should never have the green valve closed while the compressor is running!
@@LeslieKailVillarreal I get this alarm too, this after having the unit serviced (new filters and sieve cannisters), and the handle knob for oxy open all the way. I suspect some other obstruction, but not sure how to begin troubleshooting it. Any ideas you can offer would be greatly appreciated.
Stumbled upon your channel here and although I know these concentrators in and out (Been rebuilding them for ages), I've only heard about this kind of set up used by an old band friend of mine who made glass pot smoking paraphernalia. Gonna check out your uses with this heat for sure!
You always use two wrenches when tightening fittings; one to do the tightening, the other placed on the stationary fitting as a "hold-back" . Otherwise you are going to loosen or strip adjacent connections --- and get a flashback arrestor on the propane and acetylene. I've heard the concentrator does not need an arrestor, but the oxygen tank need one too.
Great video Leslie, thank you. So do you keep the concentrator on all day while you work? And do you leave the propane tank valve open all day until you close your studio for the day? Thanks so much!
@@LeslieKailVillarreal Great! Just purchased the same set up and getting over the fear of not pooping, (lol!) I've learned so much from your classes and videos! Thanks so much!
Hi leslie, How did you connect concentrator to tube and fill with oxygen without using a compresor. What kind of tool you used, i think regulators are for decreasing the gas pressure does it also work oppositely?
Is that a 6L oxygen generator? Can you use something smaller.....a 1.2L generator? I've been wanting to change from butane torches (I have 3 different sizes for different project sizes!!) but can't afford the bigger generators right now...The smaller ones run about $100-$125.
I started using an oxygen concentrator for welding and was wondering why more people were not doing it. ”It never occurred to me ” was the answer I got most often. Once the units have run through their useful life as medical equipment I think this is a great use for what would otherwise end up in the landfills. The alarm was meant for alerting people that their hose had a kink or for some reason was restricting the flow. So the alarm will start beeping if you adjust the flow to a low flow, but you have to have a flame that might be too big for your work with the flow that keeps the alarm from going off. What to do? Install a T junction with a needle valve where the needle valve releases the extra oxygen into the room. It can then let the concentrator operate at a higher flow rate (which is actually easier on the equipment and will prolong it's lifespan as well as stopping the alarm) while using a smaller amount at the torch tip, allowing some of the smallest torch tips to be steady. Nice job on the explanation! Finally found someone else who is going tankless.
Fantastic video! Thanks so much for putting in the time to teach us all your knowledge. I know just how time consuming it can be editing videos like this so I really appreciate it!!
Hello Leslie.. I produced hydrogen and oxygen in a ratio of 2:1 by electrolysis.. It had a lot of power.. But this will be a better way as you mention Leslie.. I will also buy a Philips oxygen concentrator like you have.. I understood everything and there will be no problem put it together like this.. In the end, I still need to make ozone olive oil, I will also need a Philips oxygen concentrator there.. Thank you and greetings to the USA. Vašek CZ Europe..
Oh Leslie, I’ve been looking for you and your knowledge! I’ve taken gold and silver smithing classes, but I hesitated setting up torches at home. These videos are perfect! I’m glad I kept looking at UA-cam so that I found you!
Hi Leslie, where can I buy the regulator for the Bernzomatic tank. Thank you for your teachings, I am an admirer and follower of yours. I love your designs !!!
This is a great video and helped me with my decisions on purchasing a new torch. There are so many options out there it's difficult to choose one! I'm currently waiting on the torch and disposable regulator. I have a concentrator for my glasswork. I'll be ordering the tips also. The man I spoke to at Paige Tools was so helpful. Just wondering if there is any new info since you've been using this for awhile? Do you ever need your acetylene torch?
Thanks for making this video. I've been wanting one of these for awhile now. And I didn't know about the oxygen concentrators, they're easily found on craigslist too.
I had an epiphany the other day because I wanted oxy for a torch set up but didn’t want tanks and Lo and behold you have a WHOLE VIDEO ON EXACTLY WHAT I WANTED! Thank you!! Oxygen concentrator setup is brilliant, and you simplified it for everyone.
Such a great video and great information. Thanks so much for the detailed posting. For those of you that don't have an Airgas dealer near you, I ordered the following parts from Amazon and they worked great for hooking up my Smith Little Torch to the concentrator: Fomey 60332 Hose Coupler Set & Forney 60326 Hose Repair Kit. Between those 2 - you'll have everything you need. Hope this helps someone else.
Hi Leslie, I just found 4 of those Everflo units by a dumpster today at a Medical oxygen supply company. They cut the power cords off. My plan is to put a power cord on one and see what happens. I've already opened it up and plan to fix it if it needs repair. I have a welding shop here in my garage and had no idea about these oxygen generators. How cool! I love your video by the way!
As a glassblower for a few years, I have always known to use the acronym P.O.O.P... When lighting its propane/oxy, then when turning off its oxy/propane.... Thats where flashbacks come into play.. But, always when lighting, fuel first light the torch and then your oxy.. When turning off its oxy then fuel.. Dont blow yourselves up kids...
Thanks for the info! I was wondering if it was possible to use one of these for the little torch. Just ordered one of these mini torch kits to use for a whole host of things ranging from hobbies to AC/refrigeration brazing and personal car repair tasks like heating around a stuck bolt which takes forever with a conventional propane only torch. I wouldn't want to use the concentrator in the shop area with all the dust dirt and humidity, but for the work table in a climate controlled area this appears to be the best option!
Thank you so much for this video. I just got home with an oxygen concentrator that I purchased on Craigslist with less than 700 hours on it. I didn't know if there would be anything on UA-cam about using an oxygen concentrator and your video was everything I needed. Really excellent instruction!
Thank you so much for this info! I have a glass torch on a 5 lpm oxygen concentrator and it's hooked up like something from Mr. Wizard's lab 'cause I couldn't get the right fittings...now I know what to ask for!!! Love your videos and can't wait to take one of your online classes!
Thank you so much! I have a Smith Little and have used it for many years with oxy acetylene. Recently inherited a brand new large oxygen concentrator from my brother who passed away and didn't know how to incorporate the Smith with it - thank you thank you for the lesson - changed everything for me.
You should put a little condensation bottle right where the air comes out of the oxygen machine then tying your hoes that goes to your torch. That would protect the unit much better from any mishaps that might happen.
still love your videos 😍I have used many torches, hoke, orca i use a smith little torch from time to time. my favorite is the smith silver smith. i have 5 tips for that one i use a #2 or #3 for melting an ounce or two in the crucible. but normally i use a #0 or #00 primarily. great video as always, seems most people only know smith little torch.
Hi Leslie thanks for the video. Tell me please how have you got on with the smith torch and oxycon? I've got to move on from the setup that I currently have as it's so limiting. I have a Sievert propane only torch that I use with a needle point nozzle (because I want and I want a concentrated heat pattern) I want to use the glass beads that I make and a bigger nozzle will damage the beads. I don't know if I should go for a Smith torch and use my 4LPM oxycon with that or get one of the brazing kits that are made for the refrigeration industry. As an example I want to solder a 50mm long 4mm X 3mm piece of sterling to a 150mm long X 50mm wide sheet of 1mm thick silver along with two lengths of 2.5mm wire each about 80mm long to make a cuff but the wires will have beads in then so I can't get it all hot at once. Kind Regards . . Andy
Hello Andy, yes I’ve been using the set up and Todd thousands of students to use it as well. It’s the only set up I have in my studio and I love it Bree oxygen you can’t beat right? You can really do a lot with this torch you can use the tiny little Smith tips, that will give you a pencil tight pinpoint flame or you can use the large rosebud tips for raising or alloying or fusing. It’s wonderful you won’t regret it.
This is super helpful, Leslie, as I have started looking into oxygen concentrators, but haven’t really known what to look for - or how to use it. Will this setup generate enough heat and pressure for long enough to do sand casting? I just have a setup to do rings and other similarly sized objects, so nothing really big, but I was taught to use a rosebud tip, which obviously produces a really big flame.
What about using mapp gas as it burns hotter or is that not desirable ? Nice video for me as I've been soldering and welding a long time and I never seen stuff like you're showing, it's just great !
Just ordered an oxygen concentrator from Etsy. I’m going through tanks too fast and it’s 104$ a pop to fill em. The place I’m getting oxygen actually is an air gas, name and all, so I’m going to try and go there with the information you provided and hopefully I can get what I need. Then come home, set it up and be ready to go. The option of only paying for propane will be such a relief. Edit the concentrator I got is actually the same one you have. Now I just have to wait for it to get here, should be a few days. I can’t wait man, I won’t be afraid to go down and use my torch, feeling pressured to make what I need. It’s a pain to get that oxygen tank out to the car from where it is in my house. I know that it doesn’t burn as pure as an oxygen tank but idc it will work. I’m running it on a bobcat GTT one stage torch, and I mainly make marbles and pendants. Thank you so much for the video and information on how to do this
@@jewelsmythe3111 I subscribed to your channel as well. I have a question would you be able to just connect the green hose to the concentrator? Or do you really need a flashback arrestor, I can go get the bits you said I need but I can also just cut the green hose and put it on the nipple
Thank you so much for posting this. Extremely helpful, best and most straightforward and detailed information I've found and I've been looking for awhile
Just an fyi for everyone; we are putting our setup together and got 1/4” clear pvc hose, but it was OUTSIDE diameter and the fit was too tight, so we figured out that you need to make sure that you get 1/4” INSIDE DIAMETER clear tubing.
Oxygen concentrators work using a molecular sieve - so the flow rate regulator also adjusts how pure your oxygen is. If your machine is rated at "5lpm", it usually means that your oxygen will be 55-70% pure at 5lpm, and all the way up to 90-98% pure at 1lpm. So you *should* limit the flow if you're doing smaller work. Makes for a hotter flame.
Your machine needs servicing. A properly working machine will maintain 95% at 5lpm. I have two machines, one 21000 hours and one 44000 hours (compressor and valve pack rebuilt) and both put out 95% at 5lpm. Both have the original sieve canisters.
@@glasslinger I don't have one(yet), but what I meant in this comment is that most concentrators are medical, and their ratings are often overstated for marketing purposes. In my experience shopping for them, almost every single unit has a number stated higher than the concentration specified in the datasheet in finer print. Most 5lpm models I've seen are only rated at around 70% @ 5lpm, and the concentration goes up the lower the flow rate is set(90% @ 3lpm, 98% @ 1lpm, and so on). The only exception to this I've seen so far is units from Philips Respironics(I believe they're popular in the US) and Bitmos. Their units seem to genuinely output the highest stated concentration at any flow rate.
@@glasslinger You're totally right about that. With new sieve beds, these concentrators should still put out > 90% oxygen at the highest flow rate. What I DON'T like about this model (I have the same one), is that if you do want a lower flow rate (say 1 LPM instead of 5 LPM), it still produces a bit over 5 LPM and it just bleeds out the rest of the pure oxygen from a valve inside the machine. There are other O2 concentrators that actually adjust down the compressor speed so it takes less power and your sieve beds last much longer.
Awesome video! I had no clue you could do this with an oxygen concentrator. Thanks for taking the time to explain the set ups. Curious, can you run a concentrator with an acetylene tank? Seems like it might just work? Looking at possibility of using a regular sized torch and cutting 1/4 inch steel. Possible?
Know I'm being picky but you refered to the small propane tank regulater as a disposible. I'm sure you ment the tank was disposable not the regulator. great video though lot of ideas to work with. LL&P Lloyd.
Leslie, Do I need to adjust the lpm per each size tip? Number 7 tip - use 5lpm and the smaller number 2 tip - use a lower lpm??? THANKS! Great video! Finally got my concentrator and all set up.
I have the same exact concentrator I just picked up at a local sale. Every time I try to add the oxygen to the propane after it’s lit, the flame goes out. What should I be doing differently? I’m following instructions as in the video. I have a size 3 tip on. Any insight is appreciated-this thing scares me hahaha might have to go back to mini butane torches 🤦🏻♀️
Try using the largest tip, be sure to let the concentrated run at least 3 min it needs to build up oxygen. If it still won’t light, and have more than 10,000 hrs on it it needs to be re furbished. If u have flash back arrestees try removing them and try again to light it
Is it possible to melt large amounts of metal with the oxygen device? Probably not with the small flame or can you also connect a large burner? So is it applicable for casting or only for soldering work?
The Ability to melt larger quantities of metal would depend on the torch you have .the oxygen would be the same coming from a tank or from the concentrator would make no difference
Hi, I notice at the end when you are using the Smiths torch with propane and the oxygen concentrator, the tip on the torch is not the supplied smiths item…Can you tell me what it is? Cheers John…UK
Nope you didn’t miss it. I didn’t cover any set up with the acetylene torch. I actually said in the video that I was getting rid of my acetylene torch and tanks and moving on to a oxygen concentrator, and a disposable propane tank. I got rid of my Smith handy heat torch because it uses only acetylene, it does not work with compressed oxygen.
Thank you! The timing for finding this video was perfect as I just bought a used O2 concentrator for $100 and a disposable propane tank. Because my new studio is adjacent to my living area I wanted to get rid of the tanks. I've been using a creme brule torch but that's a pain! I've been hesitant to set up the new system but now I'm confident that it's simple and I can do it safely. Goodby BBQ fuel tank and O2 tank. I'm so grateful for you and all the knowledge you share!!
This was addressed in the video if your concentrator is beeping, that means your oxygen torch valve is closed. It must always be open when the concentrator is running except for the moment, you turn it off to light the torch. Once it starts beeping you have to turn off the unit and restart it again And make sure you open your green torch valve first.
Fab video Leslie. As always. Just got oxycon and smiths. Quick question. You show the on off procedure for each session. When you are working with the set up I presume you turn green valve on first then red on the torch. If you're turning off for a few mins then do you turn of red then green on torch but not at the tanks. Is that okay or do you need to turn everything off even for just a few mins. Does that make sense?
Sue Coppock hi yes that’s correct..green valve is always open, except for whet u are lighting the torch. Then u turn it off while u are lighting propane. Always turn off propane when it’s flame is off. Run off the propane to put ou the flame an leave green on
Is the oxygen as good as the cylinder type? Could a domestic propane gas cylinder be used? I find a domestic propane cylinder works well but I still need commercial oxygen. This might be an idea.
Cylinder type are you talking about a tank? I think I covered that in the video this video is about getting away from using cylinder tanks and using an electric concentrator that will make oxygen for you, therefore, you never have to purchase it and yes, it works just as well and much safer than an oxygen tank. My whole point of making this video is to teach people how to get away from having those serious tanks and their studios because they’re usually not covered by insurance.
@@LeslieKailVillarreal I had oxy acetylene and found that Propane worked just as well and no rental for fuel. Getting rid of the oxygen cylinder would be a plus if the gas is as good or near as good as the tank type.
Thank you so much! Ran out of oxygen and my local AirGas just closed...I was begging my son to help me with his truck until I did some you tube surfing and found this. So informative and helpful! Great video!
You really shouldn't be using that clear tube for your O2, when it is exposed to pure or high concentration o2 the tube becomes rather flammable. I know from experience, small leak and a spark caused the hose to burn back like it was a fuse. Not fun
Most Anything is flammable if you hit it with a flame!! Please know you have to use caution and care with any flame . My flame never goes anywhere near that plastic hose. It’s at least 5 feet away from my soldering station.
@@LeslieKailVillarreal I'm more than aware. Can't always help sparks, sometimes they like to go pretty far, but oxygen definitely makes certain materials far more likely to ignite than it does to others and that tube at least the clear stuff tends to be nylon, nylon for what it's worth can saturate with pure oxygen making it burn quickly like a fuse. While I get that it works, welding hose is cheap enough at places like harbor freight or Amazon and is less likely to catch fire cause it is made out of materials that won't saturate like the clear stuff so for safety it's better to avoid. But to each their own
I was taught the acronym P.O.O.P. propane oxygen oxygen propane I run a Bethlehem beracuda and I'm trying to figure out how I should make o2...a 24 volt copper wire in water will make oxygen separate from the hydrogen as long as ur build domes the o2 you can bleed off the hydrogen....paying for one just doesn't sound like the medical ones will work for me since I have a like 30mm wide outer and surface mix centerfire...I like surface mix its quiter I sell propane and propane assesories
@@LeslieKailVillarreal Oh wow, that is great to hear. I just bought one in almost new condition (thank you Covid!) and after 20+ years at the bench I'm making the switch. Thanks for the great video, all the best.
Thank you! I have seen the Oxy con tank connected to another torch called Nortel minor and it worked that way, I just committed to getting the Oxy con but don't have the right torch yet. Will see how that works with a little propane bottle and if it works I will eventually get rid of my acetylene too, thank you for the video
Yes, and I believe I addressed this in the video if your machine is beeping it’s because your oxygen flow is blocked so you probably have your torch valve turned off make sure your green valve of your torch the Smith little torch that is always is open when you’re machine is running
@@LeslieKailVillarreal Weird - my valve is open but the machine still starts to beep after about a minute of being on. It also will not go above 2LPM. Any ideas?
MADRE MÍA! DESPUES DE MUCHAS SEMANAS BUSCANDO INFORMACIÓN, AL FINAL ENCONTRÉ JUSTAMENTE LO QUE BUSCABA!! Muchas gracias Leslie, me has ayudado a despejar mis dudas en todo lo que has descrito. Te has ganado mi like y un suscriptor mas. Sé que lleva 7 años este vídeo, pero sigue teniendo un valor incalculable. gracias!! muchísimas gracias por estar ahí.
I just lucked into two oxygen concentrators. I bought a smiths little torch and didn’t know how to set it up, so this video is great. One of the concentrators is exactly like the one in the video. They are both 5 ml. I’ll probably use the blue one because it’s a little less noisy.
Hi Leslie Few months ago I bought a non-disposable propane gas tank (large bottle), and two regulators ( for oxy and gas), with two arestors. To refill the bottle with the oxygene is really expensive , I learned that after I spent all the money for this equipment. Now, after watching your video , I found an oxygene generator . But I would like to keep using my non-disposable propane bottle . Could you please inform me whether this combination is no problem? Should I keep the regulator w/arestor on the propane tank, and use the oxygene from generator as you showed In this video ( plus maybe arestors)? Thank you for your help- in advance :))) Beata
Hi! Thanks for such an informative video. I'm quite new to all this so it's been awesome to be able to find resources like this. I have a couple questions...on the website Paige Tools says you can use all the tips with an oxygen concentrator and a disposable propane tank, even the MX. Have you used the MX with your concentrator/disposable propane tank before? The melting tip you can buy from Smith says it's not compatible with an oxygen concentrator or a disposable propane tank, which is why i'm wanting to double check. Thanks so much!

so when I saw those 4 EveryFlo Oxygen generators next to the dumpster, the first thing I thought of was - oh wow, I need a clear low flow regulator for my nitrogen set up... then I thought... hmmm wonder what else is inside that case that I can pilfer and use elsewhere. So now I'm convinced I'll have 4 working oxy generators. Now I have to go and buy a silver smith torch set. I only have about 9 oxy/acetylene torches and about 20 tanks...
I just discovered your videos and in the nick of time! I watched this video yesterday and looked on Craigslist, found an Oxygen concentrator for $195 and bought it today! Next step is to purchase the Smith Little Torch, propane tank and all the other needed items. Thank you for your video and I am a new subscriber!
Well, NOW I hafta look …. The problem I am having MUST be because it’s the inner diameter… i will look for outer - thank you. i was thinking, damn, she’s got some magical powers if she got this on!
The Mecco torches are the preferred torches used by most jewelers in the industry. i also have a Smith Mini and the two are probably interchangeable as far as efficiency. I also use a propane and small oxygen tank but the generator seems like a great idea.
i like to light the propane on fire so it doesnt stink when your done lol. also mini torshes i would deff have a flash back arrest on the lines are easily burned threw and the gas inside the line will char the entire line quickly spreading!
You can also find all those fittings on Ebay cheap. I just found a crimping tool for the brass sleeve that goes around your hose and fitting. The crimping tool looks like a vice grip but has 2 different size holes for regular diameter welding hose and the smaller size.
Good video. I have been thinking about working with precious metals since I graduated from college, and decided to make a living melting gold for different uses, as the recession caused by the pandemic made things difficult for many of us.
THANK YOU FOR THE GREAT VIDEO MY QUESTION IS THE ADAPTOR ON YOU TORCH HOSE LOOKS BIGGER THEN THE ONE ON MY LITTLE TORCH. DID YOU CHANGE THEM AND WERE CAN I FIND THE CONNECTORS I NEED FOR THE PROPANE BOTTLES THANKS AGAIN
Very good video and outstanding choice of Smith (now owned by Miller) equipment.
If someone lucks out and scores a concentrator with the pump for refilling medical oxygen cylinders they can do that too and have a very portable setup for demos or whatever.
The Handi-Heet is also an excellent torch for joining copper pipe so you can repair and modify your plumbing for very little money if you're so inclined. Jewelry work is the most precise torch work. Compared to that ordinary torch soldering, brazing and gas welding are easy to learn.

Love your Steve Miller shirt!
You always use two wrenches when tightening fittings; one to do the tightening, the other placed on the stationary fitting as a "hold-back" . Otherwise you are going to loosen or strip adjacent connections --- and get a flashback arrestor on the propane and acetylene. I've heard the concentrator does not need an arrestor, but the oxygen tank need one too.
Just slip a steel tube inside the oxy line. Fire can and will burn up the line.
Great video Leslie, thank you. So do you keep the concentrator on all day while you work? And do you leave the propane tank valve open all day until you close your studio for the day? Thanks so much!
Nope! I turn it off after each soldering

For those of you that don't have an Airgas dealer near you, I ordered the following parts from Amazon and they worked great for hooking up my Smith Little Torch to the concentrator: Fomey 60332 Hose Coupler Set & Forney 60326 Hose Repair Kit. Between those 2 - you'll have everything you need. Hope this helps someone else.
LA Osborne thank you for sharing that!
FORNEY FOR BOTH!
Hi Leslie, I just found 4 of those Everflo units by a dumpster today at a Medical oxygen supply company. They cut the power cords off. My plan is to put a power cord on one and see what happens. I've already opened it up and plan to fix it if it needs repair. I have a welding shop here in my garage and had no idea about these oxygen generators. How cool! I love your video by the way!
As a glassblower for a few years, I have always known to use the acronym P.O.O.P... When lighting its propane/oxy, then when turning off its oxy/propane.... Thats where flashbacks come into play.. But, always when lighting, fuel first light the torch and then your oxy.. When turning off its oxy then fuel.. Dont blow yourselves up kids...
No clamps needed...?
thanks mrs Leslie. a lot easier to handle the concentrator rather than the oxigen cylinder.
Unbelievable, she gives clear instructions , all the detail and people still ask "what size was that fitting "...
no kidding!
Thanks for the info! I was wondering if it was possible to use one of these for the little torch. Just ordered one of these mini torch kits to use for a whole host of things ranging from hobbies to AC/refrigeration brazing and personal car repair tasks like heating around a stuck bolt which takes forever with a conventional propane only torch.
I wouldn't want to use the concentrator in the shop area with all the dust dirt and humidity, but for the work table in a climate controlled area this appears to be the best option!
Thank you so much for this video. I just got home with an oxygen concentrator that I purchased on Craigslist with less than 700 hours on it. I didn't know if there would be anything on UA-cam about using an oxygen concentrator and your video was everything I needed. Really excellent instruction!
Thank you so much for this info! I have a glass torch on a 5 lpm oxygen concentrator and it's hooked up like something from Mr. Wizard's lab 'cause I couldn't get the right fittings...now I know what to ask for!!! Love your videos and can't wait to take one of your online classes!
I was just going to throw one of them out and came across your video..... Will be nice to have around Thank You
Thank you so much! I have a Smith Little and have used it for many years with oxy acetylene. Recently inherited a brand new large oxygen concentrator from my brother who passed away and didn't know how to incorporate the Smith with it - thank you thank you for the lesson - changed everything for me.
you are so welcome darlin!
Interesting video Leslie. Lots of very handy information. Thanks Leslie. All the best.
Thank you!
You should put a little condensation bottle right where the air comes out of the oxygen machine then tying your hoes that goes to your torch. That would protect the unit much better from any mishaps that might happen.
still love your videos 😍I have used many torches, hoke, orca i use a smith little torch from time to time. my favorite is the smith silver smith. i have 5 tips for that one i use a #2 or #3 for melting an ounce or two in the crucible. but normally i use a #0 or #00 primarily. great video as always, seems most people only know smith little torch.
I also use a blow pipe torch
@@LeslieKailVillarreal you got me on that one beautiful 😍. I am not familiar with a blow pipe torch. you should do a video on that one 😁
Hi Leslie thanks for the video. Tell me please how have you got on with the smith torch and oxycon?
I've got to move on from the setup that I currently have as it's so limiting. I have a Sievert propane only torch that I use with a needle point nozzle (because I want and I want a concentrated heat pattern) I want to use the glass beads that I make and a bigger nozzle will damage the beads. I don't know if I should go for a Smith torch and use my 4LPM oxycon with that or get one of the brazing kits that are made for the refrigeration industry. As an example I want to solder a 50mm long 4mm X 3mm piece of sterling to a 150mm long X 50mm wide sheet of 1mm thick silver along with two lengths of 2.5mm wire each about 80mm long to make a cuff but the wires will have beads in then so I can't get it all hot at once.
Kind Regards . . Andy
Hello Andy, yes I’ve been using the set up and Todd thousands of students to use it as well. It’s the only set up I have in my studio and I love it Bree oxygen you can’t beat right? You can really do a lot with this torch you can use the tiny little Smith tips, that will give you a pencil tight pinpoint flame or you can use the large rosebud tips for raising or alloying or fusing. It’s wonderful you won’t regret it.
It would be a better setup if a Ferrell or hose clamp was used on your clear hose connections.
This is super helpful, Leslie, as I have started looking into oxygen concentrators, but haven’t really known what to look for - or how to use it.
Will this setup generate enough heat and pressure for long enough to do sand casting? I just have a setup to do rings and other similarly sized objects, so nothing really big, but I was taught to use a rosebud tip, which obviously produces a really big flame.
What about using mapp gas as it burns hotter or is that not desirable ? Nice video for me as I've been soldering and welding a long time and I never seen stuff like you're showing, it's just great !
Thanks for the post, Mapp gas is not suited well for jewelry .
But why mommy ? ?
Just ordered an oxygen concentrator from Etsy. I’m going through tanks too fast and it’s 104$ a pop to fill em. The place I’m getting oxygen actually is an air gas, name and all, so I’m going to try and go there with the information you provided and hopefully I can get what I need. Then come home, set it up and be ready to go. The option of only paying for propane will be such a relief.
Edit the concentrator I got is actually the same one you have. Now I just have to wait for it to get here, should be a few days. I can’t wait man, I won’t be afraid to go down and use my torch, feeling pressured to make what I need. It’s a pain to get that oxygen tank out to the car from where it is in my house. I know that it doesn’t burn as pure as an oxygen tank but idc it will work. I’m running it on a bobcat GTT one stage torch, and I mainly make marbles and pendants. Thank you so much for the video and information on how to do this
awesome! you will never look back!
@@jewelsmythe3111 I subscribed to your channel as well. I have a question would you be able to just connect the green hose to the concentrator? Or do you really need a flashback arrestor, I can go get the bits you said I need but I can also just cut the green hose and put it on the nipple
Leslie are you still loving it.Really thinking about getting one.Does it get hot enough for soldering layers of silver?
Darlene R yes I am love being free of the big tanks. The heat is excactly the same no difference than what u get u get from a huge tank. Solder on !!!
Thank you for making this video. Very helpful. I learned something new.
I'm so glad!
Thank you so much for posting this. Extremely helpful, best and most straightforward and detailed information I've found and I've been looking for awhile
Sonia Blade you're welcome! Thanks for the nice compliment😘
Great information, Leslie! I'm a beginner and appreciate this video very much! Thank you!!!
Just an fyi for everyone; we are putting our setup together and got 1/4” clear pvc hose, but it was OUTSIDE diameter and the fit was too tight, so we figured out that you need to make sure that you get 1/4” INSIDE DIAMETER clear tubing.
yes of course you need 1/4 ID because it needs to match the width of the nipple!
Oxygen concentrators work using a molecular sieve - so the flow rate regulator also adjusts how pure your oxygen is. If your machine is rated at "5lpm", it usually means that your oxygen will be 55-70% pure at 5lpm, and all the way up to 90-98% pure at 1lpm.
So you *should* limit the flow if you're doing smaller work. Makes for a hotter flame.
Your machine needs servicing. A properly working machine will maintain 95% at 5lpm. I have two machines, one 21000 hours and one 44000 hours (compressor and valve pack rebuilt) and both put out 95% at 5lpm. Both have the original sieve canisters.
@@glasslinger I don't have one(yet), but what I meant in this comment is that most concentrators are medical, and their ratings are often overstated for marketing purposes. In my experience shopping for them, almost every single unit has a number stated higher than the concentration specified in the datasheet in finer print. Most 5lpm models I've seen are only rated at around 70% @ 5lpm, and the concentration goes up the lower the flow rate is set(90% @ 3lpm, 98% @ 1lpm, and so on).
The only exception to this I've seen so far is units from Philips Respironics(I believe they're popular in the US) and Bitmos. Their units seem to genuinely output the highest stated concentration at any flow rate.
@@glasslinger You're totally right about that. With new sieve beds, these concentrators should still put out > 90% oxygen at the highest flow rate. What I DON'T like about this model (I have the same one), is that if you do want a lower flow rate (say 1 LPM instead of 5 LPM), it still produces a bit over 5 LPM and it just bleeds out the rest of the pure oxygen from a valve inside the machine. There are other O2 concentrators that actually adjust down the compressor speed so it takes less power and your sieve beds last much longer.
Awesome video! I had no clue you could do this with an oxygen concentrator. Thanks for taking the time to explain the set ups. Curious, can you run a concentrator with an acetylene tank? Seems like it might just work? Looking at possibility of using a regular sized torch and cutting 1/4 inch steel. Possible?
I don’t see any reason that you couldn’t.
Know I'm being picky but you refered to the small propane tank regulater as a disposible. I'm sure you ment the tank was disposable not the regulator. great video though lot of ideas to work with. LL&P Lloyd.
And I hope I’m not being picky, but you spelled “meant” wrong 😍😝🙃
Leslie, Do I need to adjust the lpm per each size tip? Number 7 tip - use 5lpm and the smaller number 2 tip - use a lower lpm??? THANKS! Great video! Finally got my concentrator and all set up.
Nope!
I have the same exact concentrator I just picked up at a local sale. Every time I try to add the oxygen to the propane after it’s lit, the flame goes out. What should I be doing differently? I’m following instructions as in the video. I have a size 3 tip on. Any insight is appreciated-this thing scares me hahaha might have to go back to mini butane torches 🤦🏻♀️
Try using the largest tip, be sure to let the concentrated run at least 3 min it needs to build up oxygen. If it still won’t light, and have more than 10,000 hrs on it it needs to be re furbished. If u have flash back arrestees try removing them and try again to light it
Is it possible to melt large amounts of metal with the oxygen device? Probably not with the small flame or can you also connect a large burner? So is it applicable for casting or only for soldering work?
The Ability to melt larger quantities of metal would depend on the torch you have .the oxygen would be the same coming from a tank or from the concentrator would make no difference
Tanks for the Video.
Do you use flashback arrestors on your Smith Little Torch?
Patricia Carlson This is covered in the video
@@LeslieKailVillarreal you mentioned that you didn’t have them on but never said where they go. Where do they go, please?
very excellent video , now all I need is to find a portable oxygen concentrator that puts out 5 liters.
5 to 7 liters works. Good luck
Great detailed tutorial and how to video, thanks! This is very helpful.
My pleasure!
I just got one of these concentrators and your video is absolutely fantastic! Thank you!!
Thank you hun!
Hi, I notice at the end when you are using the Smiths torch with propane and the oxygen concentrator, the tip on the torch is not the supplied smiths item…Can you tell me what it is?
Cheers John…UK
This torch works best with multiport tips from Otto Frei called Impgen ox tips
Thank you! I wondered if I missed the acetylene valve set up with the smith handi heet?
Nope you didn’t miss it. I didn’t cover any set up with the acetylene torch. I actually said in the video that I was getting rid of my acetylene torch and tanks and moving on to a oxygen concentrator, and a disposable propane tank. I got rid of my Smith handy heat torch because it uses only acetylene, it does not work with compressed oxygen.
Thank you! The timing for finding this video was perfect as I just bought a used O2 concentrator for $100 and a disposable propane tank. Because my new studio is adjacent to my living area I wanted to get rid of the tanks. I've been using a creme brule torch but that's a pain! I've been hesitant to set up the new system but now I'm confident that it's simple and I can do it safely. Goodby BBQ fuel tank and O2 tank. I'm so grateful for you and all the knowledge you share!!
I am interested in knowing if you are still using this setup?
Yes I am!
How do I make the concentrator on o stop beeping?
This was addressed in the video if your concentrator is beeping, that means your oxygen torch valve is closed. It must always be open when the concentrator is running except for the moment, you turn it off to light the torch. Once it starts beeping you have to turn off the unit and restart it again And make sure you open your green torch valve first.
Fab video Leslie. As always. Just got oxycon and smiths. Quick question. You show the on off procedure for each session. When you are working with the set up I presume you turn green valve on first then red on the torch. If you're turning off for a few mins then do you turn of red then green on torch but not at the tanks. Is that okay or do you need to turn everything off even for just a few mins. Does that make sense?
Sue Coppock hi yes that’s correct..green valve is always open, except for whet u are lighting the torch. Then u turn it off while u are lighting propane. Always turn off propane when it’s flame is off. Run off the propane to put ou the flame an leave green on
Is the oxygen as good as the cylinder type? Could a domestic propane gas cylinder be used? I find a domestic propane cylinder works well but I still need commercial oxygen. This might be an idea.
Cylinder type are you talking about a tank? I think I covered that in the video this video is about getting away from using cylinder tanks and using an electric concentrator that will make oxygen for you, therefore, you never have to purchase it and yes, it works just as well and much safer than an oxygen tank. My whole point of making this video is to teach people how to get away from having those serious tanks and their studios because they’re usually not covered by insurance.
@@LeslieKailVillarreal I had oxy acetylene and found that Propane worked just as well and no rental for fuel. Getting rid of the oxygen cylinder would be a plus if the gas is as good or near as good as the tank type.
like I said, Propane with oxygen concentrator.
Thank you so much for this video, this is exactly what I was looking for. The way you explain it and the tips you gave us were great!👍👍.
Thanks hope u can take a class with me!
@@LeslieKailVillarreal Yes, will be wonderful 😁👍.
O2 ref
Thank you so much for posting this! Super helpful
Thank you so much! Ran out of oxygen and my local AirGas just closed...I was begging my son to help me with his truck until I did some you tube surfing and found this. So informative and helpful! Great video!
You really shouldn't be using that clear tube for your O2, when it is exposed to pure or high concentration o2 the tube becomes rather flammable. I know from experience, small leak and a spark caused the hose to burn back like it was a fuse. Not fun
Most Anything is flammable if you hit it with a flame!! Please know you have to use caution and care with any flame . My flame never goes anywhere near that plastic hose. It’s at least 5 feet away from my soldering station.
@@LeslieKailVillarreal I'm more than aware. Can't always help sparks, sometimes they like to go pretty far, but oxygen definitely makes certain materials far more likely to ignite than it does to others and that tube at least the clear stuff tends to be nylon, nylon for what it's worth can saturate with pure oxygen making it burn quickly like a fuse. While I get that it works, welding hose is cheap enough at places like harbor freight or Amazon and is less likely to catch fire cause it is made out of materials that won't saturate like the clear stuff so for safety it's better to avoid. But to each their own
I was taught the acronym P.O.O.P. propane oxygen oxygen propane
I run a Bethlehem beracuda and I'm trying to figure out how I should make o2...a 24 volt copper wire in water will make oxygen separate from the hydrogen as long as ur build domes the o2 you can bleed off the hydrogen....paying for one just doesn't sound like the medical ones will work for me since I have a like 30mm wide outer and surface mix centerfire...I like surface mix its quiter
I sell propane and propane assesories
I am intetested to hear how you liked that setup and if you are still using the oxygen concentrator with your Smith little torch? Thanks
Still loving it, still using the same torch in the exact same concentrator I filmed in this video
@@LeslieKailVillarreal Oh wow, that is great to hear. I just bought one in almost new condition (thank you Covid!) and after 20+ years at the bench I'm making the switch. Thanks for the great video, all the best.
Can the little smith ve used for makibg lampwork beads like the minor maybe with a rosebud ?
I’m not sure
Thank you! I have seen the Oxy con tank connected to another torch called Nortel minor and it worked that way, I just committed to getting the Oxy con but don't have the right torch yet. Will see how that works with a little propane bottle and if it works I will eventually get rid of my acetylene too, thank you for the video
Hi there! Do you ever have an issue where the everflo starts beeping with the red and yellow lights on after a few minutes of being on?
Yes, and I believe I addressed this in the video if your machine is beeping it’s because your oxygen flow is blocked so you probably have your torch valve turned off make sure your green valve of your torch the Smith little torch that is always is open when you’re machine is running
@@LeslieKailVillarreal Weird - my valve is open but the machine still starts to beep after about a minute of being on. It also will not go above 2LPM. Any ideas?
MADRE MÍA! DESPUES DE MUCHAS SEMANAS BUSCANDO INFORMACIÓN, AL FINAL ENCONTRÉ JUSTAMENTE LO QUE BUSCABA!!
Muchas gracias Leslie, me has ayudado a despejar mis dudas en todo lo que has descrito. Te has ganado mi like y un suscriptor mas.
Sé que lleva 7 años este vídeo, pero sigue teniendo un valor incalculable. gracias!! muchísimas gracias por estar ahí.
Thanks for doing this video. I just set up my oxy concentrator and propane. This video was really helpful!
I just lucked into two oxygen concentrators. I bought a smiths little torch and didn’t know how to set it up, so this video is great. One of the concentrators is exactly like the one in the video. They are both 5 ml. I’ll probably use the blue one because it’s a little less noisy.
Your the best, just seting up for small repairs and hobby. The plumbing part was great. Along with all else...Thanks so much.
Hi Leslie
Few months ago I bought a non-disposable propane gas tank (large bottle), and two regulators ( for oxy and gas), with two arestors. To refill the bottle with the oxygene is really expensive , I learned that after I spent all the money for this equipment.
Now, after watching your video , I found an oxygene generator . But I would like to keep using my non-disposable propane bottle . Could you please inform me whether this combination is no problem? Should I keep the regulator w/arestor on the propane tank, and use the oxygene from generator as you showed In this video ( plus maybe arestors)?
Thank you for your help- in advance :)))

Hi! Thanks for such an informative video. I'm quite new to all this so it's been awesome to be able to find resources like this. I have a couple questions...on the website Paige Tools says you can use all the tips with an oxygen concentrator and a disposable propane tank, even the MX. Have you used the MX with your concentrator/disposable propane tank before? The melting tip you can buy from Smith says it's not compatible with an oxygen concentrator or a disposable propane tank, which is why i'm wanting to double check. Thanks so much!

Thank you for this great tutorial! You ROCK!!!!
so when I saw those 4 EveryFlo Oxygen generators next to the dumpster, the first thing I thought of was - oh wow, I need a clear low flow regulator for my nitrogen set up... then I thought... hmmm wonder what else is inside that case that I can pilfer and use elsewhere. So now I'm convinced I'll have 4 working oxy generators. Now I have to go and buy a silver smith torch set. I only have about 9 oxy/acetylene torches and about 20 tanks...
I just discovered your videos and in the nick of time! I watched this video yesterday and looked on Craigslist, found an Oxygen concentrator for $195 and bought it today! Next step is to purchase the Smith Little Torch, propane tank and all the other needed items. Thank you for your video and I am a new subscriber!
This is great info presented very well. Thank you so much!
how did you get the quarter inch tubing over the quarter in brass nipple....???? I am having a HECK of a time.....
you mean the Radner 3987 Brass nipple? Did you get a 1/4 INNER diameter hose? or 1/4 outer diameter?
Well, NOW I hafta look …. The problem I am having MUST be because it’s the inner diameter… i will look for outer - thank you. i was thinking, damn, she’s got some magical powers if she got this on!
BTW - thank you for replying … very grateful ❤
And I realize it’s vice versa I need
For those curious what's inside the unit: ua-cam.com/video/GxclrM270gA/v-deo.html BTW, I love your classes Leslie!!
Perfect, informative video. Thank you.
Great setup, and much safer, and much much cheaper in the long run. Cheers Leslie.
Not what I was looking for at all, but thanks for the effort. I wanted to see how to connect oxygen concentrator to a tank to store oxygen gas.
The Mecco torches are the preferred torches used by most jewelers in the industry. i also have a Smith Mini and the two are probably interchangeable as far as efficiency. I also use a propane and small oxygen tank but the generator seems like a great idea.
Thanks Leslie. Great on concentrator. Just bought one from Rio and now I know how to set it up!!!!
i like to light the propane on fire so it doesnt stink when your done lol. also mini torshes i would deff have a flash back arrest on the lines are easily burned threw and the gas inside the line will char the entire line quickly spreading!
Thank you so very much for this very informative video! 😊
You can also find all those fittings on Ebay cheap. I just found a crimping tool for the brass sleeve that goes around your hose and fitting. The crimping tool looks like a vice grip but has 2 different size holes for regular diameter welding hose and the smaller size.
Thank you for such a thorough and informative video!
You are so awesome! I definitely plan to take classes with you!
Excellent info thank you very much!
Hi Leslie just found your channel. Great Video’s and very informative 👌🤓
hi Lesley, have you seen these hydrogen/oxygen generators that use electrolysis to produce Hydrogen and Oxygen gas for welding?
Good video. I have been thinking about working with precious metals since I graduated from college, and decided to make a living melting gold for different uses, as the recession caused by the pandemic made things difficult for many of us.
Great video, thanks for putting this together and sharing!
I don't think that will cut 3/8 soft metal sheet.
Very nice quite informative Thank you.
THANK YOU FOR THE GREAT VIDEO MY QUESTION IS THE ADAPTOR ON YOU TORCH HOSE LOOKS BIGGER THEN THE ONE ON MY LITTLE TORCH. DID YOU CHANGE THEM AND WERE CAN I FIND THE CONNECTORS I NEED FOR THE PROPANE BOTTLES THANKS AGAIN
