I have a brand new Smith Little Torch Oxy-Acetylene outfit and am new to brazing in general, have done lots of propane soldering on water pipes etc. but no brazing. I want to get up to speed really quick on brazing sheet metal so I can start restoring a '75 GMC dumptruck.
I am having trouble knowing if I have the flames recognized properly - carburizing, neutral, oxidizing. And in general how large a flame to use on sheet metal.
Any videos or advice anyone can give me?
