    There is a leak somewhere. But I'm sure a good tightening will fix that issue. What I need help with is that one of the on off knobs was "pushed in". I pulled it out into place. But I have no idea how it works. Doors that mean its ok to use? Or is the whole torch set trash?

    Thanks

    You're talking about an acetylene torch? If so, given the fact that you have to ask, you really should bring it to someone qualified to work on it. If that is the acetylene valve that is leaking, you could blow your hand off (or worse) with a leak.

    Are you talking about a oxy-acetylene/propane torch set? What brand is it? I would just consider buying a new handle. They are not that much.

    The leak is from the 02. I can fix the leak. my main question is with the valve. if the valve is pushed in, is it broken? or since i pulled out back into place is it still good. Never worked on one so no idea how it works internally.

    The adjustment valve on the tanks or the one on the torch itself?

    Apparently the knob unscrews all the way out and is just a rod that pushes on something. The whole knob and white bushing were pushed in. That itself does not look like it would cause a problem, so i guess im at square one, wont know if it works till its full.

    From what I see from your pictures. You need a new set of gauges and new hoses.

    so its possible itl leak out of hte threads?

    gauges are only 15 bucks (the big part with the screw in knob?). so thats not to bad if i have to replace it. 80 for regulators, a little more pricey.

    First of all it looks like those gauges and regulators are old and look to be in bad shape. If the hoses outer covering are either checked, split or show excessive wear. Replace them.

    If they were mine. I would buy a new set of regulators with gauges and new hoses. I do not know about the torch you have but check it over thoroughly.

    Spray soapy water all over them and then open the tanks up but not the torch end. Look for any bubbles. No pipe dope or tape or anything. Most important NO GREASE ANYWHERE on the tanks, regulators or torch end. Grease and oxygen make explosions.

    Ok, I thought you were talking about the valves on the torch.. that's just the adjustment screw for the regulator (not a valve) -- there is no gas pressure on those threads or around that spot, so as far as that part goes, you're good to go. You screw in the handle, and it puts pressure on a diaphragm and spring. Its only way down deep in the regulator that the actual pressurized gas is.

    Just make sure that all your hoses and valves are in good shape, and be careful with it.

    please don't use an Oxy/fuel torch until you've learned how to use one. These aren't something to play around with. These aren't just a little blow torch you'd use for soldering pipes. FWIW, I'm scared of acetylene. It's very unstable and very explosive. I'm set up for propylene at my shop at school just in case a kid makes a mistake. Propylene is more forgiving. You can also run regular propane and O2. Go do some serious homework on oxy fuel torches before you hurt yourself. You can get a Victor knock off regulator for about 100 bucks at a welding store if you got one of them around you. Go to a legit welding store where they sell the gasses. Don't mess around with anything from TSC or Lowes or wherever.
