 I have gas (welder that is) and a buzz box. I
 thought I was in high cotton with those.   What
 do I need Tig for and what do I need Mig for?  
 What about this this torch and tank that Larry
 talks about?  Does that make my buzz box more
 versatile?

Dick if you have a DC welder not an AC buzz box what I explained will work. 
I'm a big ebay fan and you can find a tig torch and flow meter (not 
regulator) for under a $100.00. This will let you weld carbon and stainless. 
I have welded at nuclear powerplants and stainless pipe does require a purge 
on the back side to keep it from sugaring (usually with argon) to make an 
x-ray quality weld. On carbon steel it is not required to purge the back of 
the weld to get past x-ray but it does make a nice clean weld on the back if 
you do. This set up won't work on aluminum.
