I cant find a single video on youtube that talks about proper PSI for acetylene and oxygen regulators in regards to the smith little torch and the different tips. Regular sized torches people say 5 and 10 (7 and 12 with closed torch) Rio PLEASE make a video on this (or anyone) and or someone respond in the comments. Thank you! bout to go use my setup for the first time. wish me luck lol! watches SO many tutorials. bless

Great, thank you for the info, I appreciate it.

Hi Nicole. I’ve had this happen too. I don’t think it’s the regulator but the tank it self. I’ve noticed that sometimes they do not close completely and will leak gas into the regulator. The only things I know to suggest would be to tighten the valve down more, or go get another tank. Most supply houses have been ok with me swapping out a tank that doesn’t fully close. Mark N Tech

Just a curiosity, I have an oxy-mapp/propane jewelers torch similar to Smith from Gentec that uses disposable oxygen and mapp/propane tanks. It comes with the regulators that fit on the disposable tanks. My question is, would I need flashback arrestors for safety on this set up or is it even necessary for small disposable tanks like these?

hi Bruce...I don't have the smith but the Gentec Small torch...can I use Smith tips on my torch...and also...I purchased it from a friend...brand new in the original package...when checking for leaks I noticed a leak at the connection of the disposable oxy tank...I have it as tight as I can possibly tighten it...any ideas what may be going on?? ive tried another tank in case it was the tank but its doing the same thing.....please any help would be great..im excited to use it..thanks :)

Hi Allen, I think the Gentec torches operate similarly to the Smith Little torch, with the Little torch we do not use the flashback arrestors with the disposable tanks. The arrestors will reduce the flow of gas and hamper the performance of the torch. So we would recommend not using them with the disposable tanks. I hope this is of some help. Mark N Tech

Are there flash back arresters and reverse flow valves for the Smith Little Torch setup?

Can I use this in brazing aluminum bike frames?

I got the torch recently using dispsable oxgen and propane tanks. Can't get the flame to work on the #3 torch, even with first using only propane, barely on it wont stay lit. All the other tips i can light. It looks much eaier with the Aceetylene. any thoughts?

Hi Lana We don’t support the Gentec torch, but since it’s nearly a perfect knock off of the Little Torch I would suspect that the LT tips would work. As for the leak, you might have a bad regulator, and you could check the gasket that seals it against the tank. You can also replace it with the Smith Regulators 500093 ( propane) or 500094 ( oxy) will work. I hope this is of some help. Mark N Tech

I wish i can have that someday,watching from philippines ❤❤❤,what are the two type of tank?

Hi Wayne Unfortunately we don’t weld aluminum here so we have very limited knowledge about the techniques and how it would work with an Oxy / Acetylene torch. I wish this we could be of more help with you’re question but unfortunately we are at a loss on this one. Thank you Mark N Tech

well, I tought it would be good for fillagree work, having to to solder multiple wires on to a smal single peice?

Hi, I can't seem to get a little flame

Whats difference between ys made and Chinese?

Hi Nicole, yes. The Little Torch systems that include regulators include check valves which stop the reverse flow of gas. The Flash Back Arrestors are sold separately #500008. I hope this is of some help. Mark N Tech

im interested in this tourch can i weld aluminium and what gas are you using. im new to this so i think i prefer tourch alu weld than a mig or tig. i thought using oxigen is to cut metal.

Hello, I was going to purchase one of these torches but found out that my father has one! We tried to used it but once we would get it lit, it would stay lit for about 30 seconds then pop really loud! It sounded like a gun going off! What are we doing wrong? Also, little black ashes would fly off of it and land EVERYWHERE! Is that normal?

I have the Little Torch System with generic tanks and regulators from Harbor Freight. Whenever I shut down the system and bleed the lines my Acetylene Pressure gauge goes up again and I have to bleed the line multiple times. I even notice it going up again when I leave the house and come back hours later. Does this mean there is a leak or something wrong with the regulator?

When turning it off in the demo of the first tip you showed, after you said to turn the oxy off before the gass, you then said, "or you can do it the other way if you prefer." What do you mean??? I thought oxy gets turned off first? Then with the number 7 tip you said to turn it ALL THE WAY up till the soot stops?? I would never even think of turning it that high and that long in the small room I'm working in. I turn the thing on and off all day. By no means could I have a blasting flame like that every time... I did try, for experience, and the soot never stopped, just was way more! Why can't I just turn it on like normal?? You didn't blast it with the #2 tip... what about the other tips? What is a carbonizing flame used for, and what is an oxidizing flame used for? I thought you said in the other part one that your can't use the rose bud with acetylene. Or is that a different tip??? Also, in the other part one, you said, if your pressure isn't high enough it can pop. Or back flash! I switched to a 7 yesterday, from a 6. And I didn't change the pressure. And it kept popping after it was going for like a second after both o2 and acetylene was lit fuse for a second or so. Is that because I didn't raise the pressure?? I put the 6 back on and it was ok. Why don't you do a video showing HOW to adjust the pressure per tip, for both gases!?? Please!!!

Do you need to wear welders goggles/shield? With either acetylene or propane?

Please be more specific and define "higher pressure" on the gauges.

Hmm so # 3 us useless.
