Braze vs. Solder...need some thoughts
Well, I was sitting here thinking about something...what do you guys think is better for copper linesets? Brazing, the traditional way with torches and nitrogen....
or
Soldering with a turbo torch, flux and some #8 solder?? (no nitrogen needed)I need a new signature.....

Stay Brite # 8. Many use brazing rods without nitrogen, Stay Brite #8 would be better. Plus Stay Brite does not weaken the base metal like brazing does.
But I can do it either way, and do.Remember, Air Conditioning begins with AIR.

Ive used turbo torch in a pinch but you really need oxygen to get a hotter flame....and turbo does very poorly on large OD copper

If you are not brazing the lines with a silphos alloy, you are violating almost every manufacturers installation instructions.
If more government is the answer, then it's a really stupid question.
