What in the world is going on with my torches?

So about 2 months ago I bought a set of torches off of ebay. regulators,handle,hose, rosebud tip, pretty much everything. Well I just got my tanks on saturday and started to use them that day. They worked good. but they started acting weird right before I finished using them. I didn't think anything of it till I tried to use them tonight. First when I try to "lean" out the mixture it starts to pop like about 1,00 black cats are going off, and then usually goes out. I tried different hoses, different torch body, no dice. Could there be an air leak into the line somewhere ? I don't know what else to do. i'm running my pressure at about 25 O2 and 7Acet. And yes the hoses are hooked up correctly. :-\ I just want to cut my spring hangers off.

Any time it pops it means there is an air leak, with it popping like that I would say you deffinitely have a good air leak...double check all the fittings and make sure they are tight, including hose fittings and the fittings on the torch body...

 

[tiny2085]

ok, I'll go try that and see what happens.

use some soapy water in a spray bottle and spray it on the fittings. That will help find the leak.

I tried the soap method, and did find one leak, but I tightened it and it didn't help. I swithced the lines with another set and a different torch body, better, but it will still pop if i try to lean it out to where it should be. The flame is also not uniform, it's kind of like a star. I did just do some cutting with it, and it works, but that popping is F-ing loud. Could it be a problem with regulators ? Seems like you should expect more out of a 75$ set of torches.

I run my act at about 10-12 psi, I'm assuming you know how to adjust a tourch. The center blue tips should be chrisp and clean looking.

 

[Shawn]

Also, is your tip clean? Are all the holes open and free of debris? A tip cleaner is a must have.

Your oxygen should run around 40 and acetylene around 8.

Your oxygen should run around 40 and acetylene around 8.

thats what I usually run at also.

Clean your tip. Mine pops when the tip gets dirty. If you don't have a tip cleaner you need to get one. They are cheap and it is easy to clean the tips.

I do have a tip cleaner, and took the tip off and it looks as clean as a whistle, i'll try turning up my pressure, right now i'm only about 27 on the O2.

definately a low pressre problem that popping happens when the flame gets back inside the tip, recommended acet pressure is 4-7, oxygen is 35-45. you want to adjust to a nuetral flame when the cutting lever is not engaged. This is done by adjusting the amount of oxygen until the feather becomes one with the cone, The cone is the smallest and brightest part of the flame and the feather is the next brightest and vary's in size between carbeurizing flame and Neutral flame.

My torch did that popping crap too. Turns out it was a gasket, check those maybe.
