Morning Ralph: (AK time of course. <grin>)

CC/CV or whatever, it's a "field expedient" that "will" 
work. As most of us know anything can be MADE to work; 
regardless if it's the best or even a reasonable 
alternative to using the right tool.

Anyway, I'm not pulling anybody's leg, a mig gun can be 
converted to a tig torch. It isn't ideal but it will 
work. I didn't come up with it but was embarassed I 
didn't think of giving it a try before it was suggested 
on the list. (Artmetal if I recall correctly)

I gave it a try with my Hobart 120 Handler just to see 
if it'd work and it did ok. It wasn't like using a real 
tig torch; controlling heat was a matter of the 
separation of the tig tip from the work and the Handler 
doesn't really have the poop for it. It did weld SS 
alright but I doubt it'd have the poop for AL or CU 
alloys. Heck, I'd bet money the Handler doesn't have 
the power for low resistence alloys in any practical 
sense.

However, if you have a welder with decent power you 
should be able to weld CU alloys okay.
