Hello all! I've been looking around and would like to know what torch set up you guys use and/or which is your favorite. At my old job, we had an acetylene/air setup with some pretty big torch tips, but I quickly adapted and came to like it a lot. Now, at my new position, we use oxy/acetylene with the Smith Little Torch. Ever since I started, I haven't been able to get the hang of it; I keep burning the flux and causing quick oxidation, and my joints have become brittle and easily snap. I know that it's too hot, but when I back up and try to heat it evenly it isn't enough heat. Is this a problem that anyone else has experienced? For those of you who also have a Smith Little Torch, what is your opinion on it?
I'd love to hear about others' experiences with MAPP gas, other oxy/acetylene setups, and especially oxy/hydrogen. Additionally, I'd like to know what kind of surface you braze on - fire brick, charcoal, metal?
