I am the only guy at our company that uses oxy/acet to braze. And always use nitrogen. Everyone else thinks I'm the oddman (oddball) out. They have blind faith that soldering is just as good. I'm used to tubing benders to avoid fittings, in fact never used them on new installs. Many of my service calls are our "call-backs" and find LOTS of soldered fittings; poorly operating systems and more leaks than I could have ever expected. Not to sound tacky, but my old HVAC instructor would say "solder is for plumbers", it has its place but not in refrigeration. Every employee has a turbotorch. I refuse to solder refrig systems. The shame is our company sells TOP-OF-THE-LINE equipment. When it works poorly or fails, they simply blame the manufacturer. Please give me your comments.....I don't want to think their practices are the norm.
