Thanks so much Rio : D I was kinda nervous about doing this install for my garage workshop but your video helped me feel more confident about these dangerous additions to my jewelry making squad.
Very well done presentation. I've used O/ACC before (many many years ago) but not O/LPG and for safety reasons I watched this incase there was something I should be aware of.
Glad it was helpful!
This was a very thourogh video! Thank you!
The Smith regulators I use are essentially same for Propane and Acetylene the only difference is the fittings.
I hope this helps.
Mark Nelson
Good clear instructions, as usual with Rio. Thanks.
Thank you Sunflower, yes indeed. Ventilation is a very important factor in soldering set ups. This video was very specific in it’s function and we left ventilation to be covered in a few of our other solder set up videos. But your correct, thanks for mentioning it.
Mark N Tech
The best anagram to remember is POOP. When turning on the torch it's propane first then oxygen. Turning it off is Oxygen first then propane. So just POOP it!
lol thanks Diane. It'll stick now.
that's genius diane
I like that. I always forget lol.
@@lisaforde1641you forget how to POOP? 😂
@@jessihawkins9116 you never know.
Other trainers say to only open the propane or acetylene about one turn so it is easy to shut off in an emergency. I think opening the valve all the way is supposed to seat the valve open so there is less possibility of a leak. What do you think?
Hi Barbe. If it’s possible we leave everything set up. We’ll do our soldering and when we are done for the day we’ll turn off the tanks and bleed the lines. To bleed the lines we 1st extinguish the flame, 2nd turn off the tanks, 3rd release the gasses from the lines ( this will allow the needles to drop) and 4th release the pressure on the pressure knob by turning it to the left until you feel the tension let up. I hope this helps.
Mark N Tech
Thank you Rio, very useful.
If I switch from acetylene to propane, do I need to buy a new hose?
Someone *PLEEEASE* answer this question!
Great help and easy to understand. Thank you
Excellent instructions! Thank you.
I saw two major safety mistakes in this video. Never open flamable tank valve to the end. Crack it open just to get full pressure on gauge and stop there. That's usually about quarter of turn... In case of emergency fire you are able to quickly put out source of flammable gas and stop fire.
Same thing stands for putting out a torch. Always shut the flammable gas first, then oxygen.
That was a great video, it explained things slowly so it was easy to understand
We are glad you liked it. Thank you for watching!
@@RioGrande1944 I am a cabinetmaker, and now sell woodworking tools. My own workshop has woodworking tools and now metalworking equipment too. The addition of oxy/LPG takes my hobby time to another level.
Cheers
Hey Sealy, The torch does come with set up instruction but if you any questions at all do give a call. We can do help via email or online chat but in the case a call is the easiest way to help, just ask for tech support and any of us on the team can help. . It’s a very easy torch to set up and shouldn’t take anytime at all. Very exciting, I think you’ll love working with it.
Cheers, Mark N Tech
Thank you for the video!
Pretty down to earth presentation. I liked it.
Thank you for the video! It really helps calm the nerves. I’ve been trying to find info about appropriate eye protection. Are IR and/or UV glasses necessary for oxy/fuel setups? I’m a jeweler, but looking at some larger pieces that may require brazing. Thanks.
Julia Peralta: Not a dumb question at all. Propane is a type of LPG. Here in the US the terms are not interchanged much, most refer to propane as propane. But you will be fine using what you can get locally with the little torch. I hope this is of some help.
Mark N Tech
excellent explanation.
Is putting the flashback arrestor at the tank or torch side more safe? Thanks.
Hi Sealy
We do carry the boric acid # 704096, the alcohol is easy to find in a local hardware store in the painting section.
Mark N Tech
Actually, first step should be "blowing out" the tank valve...prior to attaching regs, crack each tank open briefly at the valve, to blow out any dirt or particles hiding in valve. THEN attach your regulators...also, best to open torch valves first, open reg line valve and open reg tank valve BEFORE you open tank main valve. EVERYTHING OPEN, to allow gas to pass through reg, line and torch to blow out any foreign junk in line AND to prevent air in line from compressing. THEN, when you hear gas flowing out the torch head, start back at the tank reg valve to set to open. Then, set the line valve to about 4 lbs. Then, and only then, close the torch valve, with the line free and clear and pressurized. Repeat for the other gas line, oxygen, e.g. W this procedure, you're flushing the system of crud, and also preventing compressed air in the lines...When finished, reverse the procedure--close TANK valve first, then purge lines by closing tank reg valve, then line valve, and finally TORCH valve, so no gas remains in lines.
I noticed your using an acetylene regulator on a propane tank. Has that given you any problems?
Nice video. SAFETY TIP: I was taught to turn off propane/acetylene first then turn off the oxygen so the oxygen can clear the line of flammable gas preventing a fire inside the torch that cannot be detected and will travel back through the gas lines - it is this scenario that makes flash arrestor necessary. Oxygen is an oxidizer and will not burn therefore turning it off last prevents a fire inside the torch and lines. I have a few years exp in the welding supply business and have seen bad things happen to great people when this is done backwards. Tired, hot, end of a long day, turn the wrong knob first, boom...
When you turn off the propane/acetylene first you get a loud pop that can be frightening or annoying to those near you. I was taught to avoid this by turning off the oxygen first then the propane/acetylene then give a quick blast of oxygen to clear the line.
keevine Strange. I always turn fuel off first exactly because if oxygen turned off first, it pops loudly. Maybe, different torches need different approach?
Mike Thompson I use injector torch, so maybe, maybe.
Did anyone get seriously hurt?
Thank you, Mark. You recommendation is very helpful. I have another question for you. Where I can get boric Acid and denatured Alcohol ? Does RIO carry them?
Mark- can you make a video about safely setting up and using an Oxy/ acetylene torch? I bought one from you guys more than a year ago and I still don't know how to use it!
Super helpful. Thanks!
This might be a dumb question but is LPG the same as propane? For the look of that tank in the video is what we call LP Gas in Mexico, I've called many gas companies asking for Propane tanks but they tell me they only sell LPG. I understand LPG is a combination of Propane and Butane. So my question is if propane and LPG are interchangeable terms in the US? I want to make sure I buy the right gas for my little smith torch.
LP-liquid propane. Same stuff rural homes use for heat, or gas bbq.
Yes. Same.
setting the pressure. You shut regulators down or turn them on ? i'm sure you met down and then turn them up until they reach pressure you want. I want to get one but i just want too be sure it's right.
I was taught to turn off the gas first so the gas don't soot up the torch when it is going out. And sometimes a pop than can dirt up your orings. Like an underpressure torch pops when it overheats. If you turn off the gas first the oxy blows out the flame clean with no smoke. Remove the tip and see if it is black.
nice videomay I ask, at the end of your video, you have what looks like a foot controlled spark generator ??where can I buy that here in the USA ?? Brand name, type, any help appreciatedthanksJohn
I feel better knowing this is something I can do in my living room.
I've read my manual...and I still turn off the oxygen first to avoid the loud pop.
I work only with oxygen/acetylene. I don't use propane anymore.
You ALWAYS turn off the OXYGEN 1st !
People that say you should turn off the combustible are simply and dangerously plain IGNORANT and know NOTHING about flammable and explosive limits.
A propane-oxygen mixture become explosive when the propane concentration fall between 2,1% and 9,5%.
If you 1st turn off the propane, at some point you will have your torch filled with an explosive mixture that is going to explode as soon as the gas flow drop below a certain rate. That's the loud "pop" stupid people hear when turning off propane 1st, and that's exactly what start FLASHBACKS.
So you always want to turn off the oxygen 1st in order to avoid to reach the explosive concentrations.
Same goes with acetylene, which is explosive from 2,5% up to 81%.
Again, you want to turn off the oxygen 1st to get above that 81% before the gas flow rate drop to the point where a flashback can be triggered.
Enjoy welding.
Thanks for the technical explanation. I was taught to do it this way but didn't know the science behind it. Ignorance is not bliss.
Yeah, my teacher in HS said "Always turn off the combustible gas first because if anything's going to start a fire it's that" but then a retired welder came into the shop while I was working on my forge after school and said "That pop you keep getting is flashback, let me show you how it should be done" and basically called out my teacher for being an idiot. Which he was.
Truth is, it really doesn't matter which gas you turn off. It is impossible for anything bad to happen. In order for the gas tank to blow up, the oxygen would have to go inside the gas tank and that is physically impossible unless the end of your torch is plugged or pressed against a wall or something.
Tank won't explode but you can get blow-outs. We had it happen back when I was in HS. Was just outside the shop and heard what sounded like a 12 ga going off; the hose blew out just under the reg.
Ummm yeah didn’t he just tell us that??
What size gas & oxygen bottles are you using there? How long would they last 1 person hobbyist? Thanks
Where can i buy those regulators
hey brett propane here in oz mainly for heating there is an abunt amount of accetalene
Great video, but I have just a propane torch connected to a propane tank that has a needle valve to regulate the type of flame. Do i need a flashback arrestor for this too?
Hi Sealy
We have a video for that on our “To Do” list. But it’s very easy to set that torch up and we can walk you through it over the phone or via chat or email, whichever you prefer.
Mark N Tech
Just another question pop out my mind. Aceylene torch is good for soldering small jewelry, like earring and rings?
Hi, where you left the oxygen and propane tanks? Is safety to have near you?
When I open the propane and oxygen the valve dosent move. Any advice?
I have used cutting torches since the late 50s.Back then it was a rule only open the acetylene or any other gas just a crack as long as the gauge moved just in case a hose breaks so you could shut of the bottle as quick as possible.Opening a crack should be enough to get a good reading of your tank as it will decrease as you use up what ever gas you are using. I never used the gauges you have so I might be all wet with these modern doodads.
They tell us in welding class to open it 2 half turn just in case a hose breaks so we can shut it off like you said
And that was acetylene, correct?? You sure they said ‘any other gas??? I just know that propane can act like a refrigerant, and if you don’t crack it enough, you’ll freeze your orifice, that’s how refrigerants work they cool way down when changing from a liquid to a gas…. Smaller orifice means more gas… my background is HVAC we traditionally use oxygen-acetylene in the trade but for home I was looking at oxygen-propane because I know what it costs to fill that acetylene tank!!
Hi Mark, I am watching how to set up a proane/ oxygen torch by you. However Lately I am thinking to get a an acetylene /atmospheric torch from RIO. Can you show us how to set up Acetylene torch?
Thanks,
Sealy
Thanks so much for the demo. I just purchased a Smith Little Torch and I was told I could use the Smith pre-set Regulator for my propane tank. It's small and doesn't have the PSI dials. Is that going to work for me? I do have a Smith Oxygen regulator like the one you have in the demo.
Hi There, Thanks for watching. This will depend on what kind of tank is being used. If disposable propane tanks are being used, then the regulators which are designed to work and fit those tanks can be used. Those do not have dials on them, but work perfectly with the disposable tanks.
It sounds like you have an oxygen regulator with the dials, so, you will be able to use refillable oxygen tanks. If you prefer to use a propane tank like the one in the video, you will need a single stage propane regulator with dials. Hope this helps!
Thank you!
Is this a Smith Little Torch? If not, is the setup the same for the Little Torch?
@gm556
A 'pop' may occur if you reverse the order. The pop throws carbon soot back into the torch, which may partially plug the gas passages.
very helpful
Hi Marc, It doesn’t work to just use the propane on an Oxy/propane system, it would be like using a candle to solder with and the flame won’t be hot enough. The propane has to mix with oxygen somehow to produce a hot enough flame for soldering and these system do that using compress oxygen so you’ll have to use the tank. The Smith regulators we sell can be used for both propane and acetylene, you will just need to make sure you have the one with the fitting for the tank size.
Mark N Tech
Thank you so much for your informative video. Hope your wife was cool with you doing that in the house.
Hi Dariusz879, You won’t need a flash back arrestor for your torch set up. Since there isn’t another tank, just the propane tank, you don’t need it. And adding one may hinder the operation of the torch.
I hope this is of some help.
Mark N Tech
Finally, some common sense. Propane won't burn without an oxidizer and oxygen can't burn without fuel. The flash back devices are a waste of money. Did none of these people take simple chemistry? The propane and oxygen don't mix until they are expelled from the end of the torch, that's why they are called "surface burning torches".
Hi I am from Australia. We do not use the term propane over here. Is propane basically LPG, which is the Australian term I think? Can I use LPG instead of propane? Thanks, great video!
Thank you so much
thanks for sharing !!!
I've never dealt with torches beyond what just connects directly to a propane or butane tank so please forgive my ignorance if im mixing up my trades... But wouldn't you want to be using PTFE? I wouldn't want to put that much torque on brass connectors just to get a seal. However, as that I've 0 experience with this type of setup I appreciate the video!
Hi there! The brass fittings do a good job of sealing from any leaks. It doesn’t require an excessive amount of torque to tighten the fitting, and they will last for many years. Hope this helps!
One may NEVER use anything combustible on any oxygen line or connection. It is begging for a disaster. Any type of polimer seal is explosively combustible in oxygen. You should also never use any grease on pressurized air connections either. Why not? Because the diesel engine was invented a century ago already. 😮
@@nicolemmer7681 lol
Thank you!
The notches in the nut indicate the left-hand thread.
Hi Sealy, you bet, the system comes with the smallest tip which is great for earrings, we do recommend getting at least 1 maybe 2 larger tips to cover the larger items.
Mark N Tech
Hello, thank you for the video. Where can I get one of those carrying outfits? Thank you.
Is it okay to leave the tanks on if I am coming back to work the next day? And I would also like to know how to shut off the tanks. is it shut off Oxy tank then shut off propane tank, bleed the line, then release the pressure?
Hello, we will pass your questions on to our Jewelry Tech Team and get you an answer.
Hello, we spoke to our Tech Team and they said to let you know that they do not recommend leaving your tanks on over night unattended. When shutting off tanks it does not matter what order you shut them down just so long as the bottles are closed. Then drain hoses and release the pressure with a t-bar on regulator. We hope this is helpful and appreciate your questions. Let us know if you have any other questions!
Thank You bro
That setup seems ideal for jewelery soldering
Mark, Thank you for all your messages. You are very helpful. I ordered a acetylene torch from RIO and also oredered two extra tips as well. However I got my 40 cf tank from a local welding store. Do you know if safety set up instruction will come with my torch order or not? If not can you e-mail me, walk me through it. My torch will get here tomorrow. Can't wait to set it up. Thank you, Mark.
I have two smith regulators both are pol fittings both lpg bottle and oxygen bottle are pol fittings can I use the smith regulators for both.
Thanks
Anthony Marsh Hi Anthony, if both the tanks and the regulators have POL fittings they should work. you might check to make sure you hose fitting fit the regulators 1st though.
Thanks for watching.
Mark N Tech
Hi, is better to have differents tanks for welding and other for melting?
Hello Maria. Thanks for your question. The only thing you need to change is the tips to do the two different processes, (casting vs. soldering). Different tanks are not required, the fuel will be the same; however, you will need a larger tip for your torch specifically for melting. Like the Smith® Little Torch™ Propane and Oxygen Multiple-Orifice Melting Tip for Propane or Natural Gas Item #: 500022 found here: www.riogrande.com/product/smith-little-torch-propane-and-oxygen-multiple-orifice-melting-tip-for-propane-or-natural-gas/500022 Hope this helps!
So what is the regulator pressure for the oxygen???
Ever figure that out? I heard him say, "Don't forget to sync the oxygen as well.
I'm sitting here with my old setup that's sitting in storage. Gotta heat this upper control arm bolt, or I'm stranded here for the night, lol
I'm going with 7s on both tanks and going for it!! 🫡
I recently used a friend's little torch (she has an amazing set up with piping and large tanks outside) and her torch was hot to the touch. I've never experienced that and now I'm freaking myself out thinking about it. Is it normal for the hand piece to get hot when soldering?
+Melissa Loggins No get a new one or something that means the flame gets to the handle (inside it)
Hi Rio Techs - I have a meco midget propane/oxygen torch and uniweld regulators and I do have flash back arrestors. I thought I was doing this correctly but I think I may have totally ruined the oxygen tank regulator because I thought that it was turned off enough. So when i opened the oxygen tank which does not open all smoothly like the one in the video, the gas hissed out loudly and I shut off the valve to the tank. Now I have the regulator properly turned off as well and the propane tank and regulator. However the oxygen tank still reads way up at 20 and I tried to redo the whole thing the right way but as soon as I opened the tank and began to turn the regulator clockwise the needle began going up even further.
It's really hard to find someone to help me with this. I studied jewelry making and worked a lot with torches but was never taught how to set one up. For safety sake I called the local airgas place where they sell welding supplies and asked if they could connect me with someone experienced who could come to my studio to help me set it up. I hoped some employee there would want to make some extra cash but they said to bring it in. I didn't want to lug my torch and tanks all the way over there so i read the directions, and tried to do it myself. mistake I guess...
Good video, though it is not good practice to crank open the oxygen all the way, for oxygen there is no need to do this and it is an important safety feature to only open it one turn so that in an emergency you can quickly shut it off.
As you demonstrated, to light up its propane/oxy, shut down the reverse. Otherwise it will pop. Important to highlight this as people get it wrong. If you hear a pop what your hearing is an explosion in the torch known as a flashback. This means you are relying on your flashback arrestors to prevent a much much larger problem. Oxygen goes off first because it’s the more combustible gas and ignites with much less effort than propane or acetylene.
Q. What size oxy tank is that?
Hello, thanks for the feedback and addressing these safety issues. We appreciate you taking the time to share this. We will pass your question on to our Jewelry Tech Team and get you an answer! Thank you for the support!
Hello, our Tech Team got back to us and they said that the tank is an R 20cu.ft tank 500050. We hope this helpful. Feel free to let us know if you have any other questions!
Actually, oxygen isn't combustible at all. The air around us is 20% oxygen, after all. However, it is essential for any fuel to burn. This includes even metals when they become hot enough. That is why you can cut steel with it, and why the oxygen is turned on last and off first. And NEVER use any steel fittings on oxygen equipment. It can start burning simply from the frictional heating caused by the pressurized oxygen flowing past it. We had such an incident at my place of work a few years ago when a contractor put a steel valve in an oxygen line. They used nitrogen to test all the lines. The first guy to open the valve after the oxygen was connected spent time in hospital.
Your welcome Rich and thank you for your kind words. The soap solution we use is a great solution as it’s safe to use on the oxygen as well as the fuel gases. It’s one of those things where you have to be safe when your being safe.
Thanks for watching.
Mark N Tech
RioTechs what do you mean? Is soap not safe???
Are acetylene regulators OK for Propane? Are propane regulators OK doe acetylene?
Industrial acetylene bottles, larger than a B than have the same valve as refillable propane bottles so they share the same regulator. However If you have been using Propane and what to switch to Acetylene or visa versa it is highly recommended to replace the regulator with a new one. The gasses can leave behind residue that can interact with the different gas and cause problems.
How about using a Oxygen Concentrator and a disposable propane tank,for safety?
Good torch setup procedure but it is also important to emphasize or even mention the importance of proper ventilation when using any torch.
Hi. I moved from Oxcy/Acet to Oxcy Propane because it's far cheaper but I dont have a gauge type regulator valve. Just a knob with bar pressure markings on it. I thought this was so because Propane is a liquid not a gas. Could I use the acetylene regulator with Propane then?
Hi Fred, thats hard to say, you can switch gases with our regulators but we're not sure about others. The best way to find out would be to contact the Mfg to see if thats possible. If you like you can email the Tech team a picture of the regulator along with the name of the Mfg and we can try to find that out for you. You can email us at technical@riogrande.com
I hope this is of some help.
Mark N Tech
RioTechs Thanks for the quick reply. I'm in the UK so that might be a problem for you. I'll approach the manufacturer here and ask. While you're on can you give me some advice about tips. Can I use those I've been using for acetylene? Some people seem to say you can. Others that you cant for reasons I dont understand.
Cheers.
fred Hi Fred. That depends on the types of type of tips you have. The Smith Little torch tips are single orifice and can be used with either gas. Most single oriface tips i have used can be used with either gas. But the multi orifice tips are a little different and specialized for either propane or acetylene. Here too feel free to send a picture of what you have and maybe we can help in some way.
Mark N Tech
RioTechs Cheers. I've discovered from a friend in the US that I need some TEN tips for the brazing I'm doing. Thanks for your offers to help.
Where can I buy this trouch kit at
Thank you Jerome.
Mark N Tech
Just a small point and I have to say I have never used such a small torch but I was always told to turn the Fuel gas off first and then the Oxygen. So I did a check with my torch supplier and as I said, on closer, fuel gas then oxygen. Maybe it is different for these small torches?
Hi Everyone
Thank you for the comments, I will try to address them all.
The set up for Oxy/Act is the same as it is for Oxy/Propane. For the Little Torch the settings are the same too.
And Keneyed209 is correct, you should make sure the fittings are clear from debris, these were new regulators and fittings so I neglected to mention that.
When setting the pressure, you start with the regulators turned off and by turning the knob to the right you set the pressure.
Mark Nelson
I think my oxygen regulator for my little smith torch is broken. I have the T knob pressure valve open and its still sending oxygen through the line. Is there as way to fix it or do I need to purchase another one?
First check that the tank is off completely and bleed the line by opening the torch. Next remove the regulator completely off the tank. Back the "T" knob out completely until it falls out in your hand. See if the dials drop down to zero. It could be a leaking tank. If they don't zero, it may be a damaged regulator.
+Mark Nelson Thanks Mark, it is a damaged regulator, just took it in for repair, thanks for responding.
What's the psi for the oxygen?
Hi There, Thanks for your question. As Mark mentions in the video, the pressure will vary depending on the torch tip you are using. You can refer to your instruction manual for that, or this handy pdf: www.smithequipment.com/files/pdf/spec_sheets/Little_Torch.pdf Hope this helps!
Do you have info on psi when using the Meco? I haven't been able to find information on pressure for it anywhere.
I'm self teaching jewelry , and I've only gone through my first tank of acetylene/oxy. I'm ready to get a refill... but now I'm totally nervous about using anything! The more safety research I do, the more Im freaking my self out. I chose acetylene because I read acetylene was safer in the home because if there is any gas floating around, it will dissipate, as apposed to propane that collects in a low laying ball of gas, meaning propane more dangerous. But now I see them say acetylene is more dangerous. Some say to turn the oxy off first in the torch, some say the gas!! I'm turning oxy off first, the gas, then it pops! Also, I heard only open the acetylene a little bit, and the oxy just a turn or so. What the heck?? This whole thing has me afraid now, and I'm usually a very coordinated, well researched person!

Regarding how each of the types of gas acts within your studio: Acetylene gas does dissipate in the air, so it will float away. Propane does settle down in the room and can cause an explosion. We hope this is helpful.
I know this comment was SEVERAL years ago, but I ABSOLUTELY AND COMPLETELY couldn't have said it better myself! There is SO MUCH conflicting info *EVERYWHERE* on this subject that it leaves someone more confused, unsure and SCARED than when they were completely UN-INFORMED! Thank you for your "rant", lol!
Why are the flashback arrestors not mounted on the torches?
+Oolong Johnson Hey there! Thanks for watching :) the flashback arrestors simply don’t fit. There are some torches, like our casting torch, where the arrestors are mounted directly to the handle. There just isn’t any room on the smaller torches like the Little torch, Swiss torch or Meco. Thanks for reaching out!
Oh ok :) thanks for letting me know
Are you sure that oxygen is turned off first ? I've always heard the fuel should be the first.
Can you set that up indoors, in the basement or does it always have to be outside ?
+Cinema Borghese Hi, you can set these up inside. I might be a good idea to check you local fire code and with your insurance company to see if it's ok. .
i hope this helps, thanks for watching.
Mark N Tech
should always open the oxygen for a short blast of air to clear out any dust from between the regular and the bottle, reason for this is if dust is inside it can compress extremely quickly when you open the oxygen causing the dust to heat up enough to catch fire, though it seams crazy it's called regulator burn out, and is and extremely common cause for torch use injury, and always pitch your lines of any residual air before attempting to light a torch
yes you need to blow out the oxy tank of using large tanks but it's not a good idea on little tanks like he has as it uses to much oxy.
6:26 it's still bubbling, lol
What is the correct pressure for oxygen?
Hi Gabriele Trovato
The correct pressure depends on the type of torch you have and which tip you are using. The correct pressure settings should be in the manual that came with your torch. If you need help with determining what is the correct pressure for your system feel free to contact us at technical@riogrande.com and we’ll try to assist you.

The real propane cutting torch
good video perfect
Does anyone know where to get a propane regulator with twin gauges? Searched for hours can't find one
Hi Rowan. Is this what you are looking for?
www.riogrande.com/Product/Smith-Single-Stage-Propane-MAPP--Regulator/500133
Thanks, Mark!
Looks like you have the wrong regulator for propane fuel. I see a red band after the 15 psi on the outlet gauge. That's indicative of a acetylene gauge. Acetylene becomes unstable and explosive at 15 psi.
@raintree27 it's fundamentally the same thing
Thank you for the video, just to dispel the hearsay, the Oxygen supply must always be the first to be shut off, because pretty much anything will burn in an oxygen rich environment.
Mark,
You need to use two wrenches mark and the crescent was used the wrong way at first.

Jerome B what do you mean?? What are the two wenches? And why?
That is an acetylene guage. It should be a propane one. Could be an acetylene regulator.
Hello, thanks for watching. We appreciate the support!
Just want to reach out with some additional information from our Jewelry Tech Team. They state the only difference between a propane and acetylene regulator is the fittings that connect to the tank.Both propane and acetylene regulators are marked as acetylene regulators. Both are fuel regulators. The only difference are the fittings. We hope this is helpful! Feel free to reach out with any other questions or concerns.
