Just out of curiosity has anyone here ever TIG welded a HVAC lineset? Usually they are brazed with an oxy/ace torch... but I would think TIG would be a possible alternative.

I my self oxy/ace torch all my ac fittings and evap or condenser repair , tig is hard to control on thin aluminum tubing http://www.muggyweld.com/?view=sitemap
I was thinking for the line sets. Copper to copper or brass to copper. Not Aluminum.
i like the ssf-6 rod . or just regular brazing rod
Remember you can also braze with TIG, no flux needed, I've done that a lot on steel, parts with silicon bronze rod. I even soldered some copper plumbing fittings once with a TIG torch as there was no other source of heat around. So for copper, with TIG, you can solder, braze or weld. Brass can be tricky cause the zinc can boil out, it all depends on the particular alloy. Some are weldable, some not.
you can tig but i think welding with gas works better since even heat and sorta hard to sweat with a tig
I never said it was easy. http://i19.photobucket.com/albums/b1...oClown/ram.gifQuote:

Yea that is what I do but figured TIG might give better welds and be cheaper in the long run.
My bro in law said his welding teacher welded chewing gum wrapper togather. I figured it was BS as all I have ever seen was paper backed with super thin AL.Quote:
