[TheForge] Soldering copper tubing in an AC unit

[Ron Childers]

Greetings all, and happy Easter. I need  to borrow your collective
brains- What is the consensus on the heat source for soldering copper
tubing in an AC unit to replace the reversing valve? The boss' "Hac man"
has burned the copper so badly it has oxidized and burned. He is using
an oxy-acetylene torch with an oxidizing flame and trying to patch the
holes he burned in it by dribbling solder in them. When that leaked he
cut the tubes back and tried to solder in new tubing he bent with a vice
and a hammer. Still leaks after three weeks and five tanks of freon... I
know but little about the esoteric science of HVAC, but Since the
oxy/ace is too hot for him would it not be better to use mapp gas,
oxy/air or? 

I am trying to get the boss to hire a professional HVAC company because
as Red Adair said, "If you think a expert is expensive, wait 'til you
hire a amateur".

Thanx in advance for your input to give me some ammunition; It is hot in
Tallahassee... Ron C
