Its just personal prefrence but I never have used an oxy/acy rig for my
regular job, I can but dont like them unless Im welding something.
Personal prefrence. I prefer a turbo torch for brazing and I use the
Mapp for soft solder on smaller water lines. Once I go over an inch
for soft solder (and thats pushing it) I use the turbo on a B tank.
BTW that Delphi thing... Fell through. Turns out they cant afford us.
LOL
I didnt care for that idea anyway. It seemed like treason to my UAW
pipefitter brothers.
