Why does my torch flameout?
I'm not a metal worker, but I thought someone here might be able to help. I have an old Benzomatic propane torch (maybe 30 years old). I rarely use it, but I needed it today to sweat come copper pipes. I have a new propane take on it. I'm using it out in the open, but sometimes after a few seconds, the flame goes out, and I have to light it again. There's plenty of gas coming out. What could the problem be?
