RE: 1/2 amp Tig welder

Jewelers use some sort of inert gas laser welder and high magnafacation 
to accuately see the work. Process was explained to me. I haven't 
actually seen it done.

Specialized medical product.  Needs to be neat and clean.  No heat
scoring.  No tip bulge bigger than the diameter.  I didn't believe it
possible either until I got a back stage tour.
Currently doing semi-mass production with a couple of rube-Goldberg
rigs.  Currently using a traditional TIG turned all the way down to 1
amp with an alternate gas.  Works reasonably well on 30ga tube with
0.003" walls, but no way to turn it lower to do the thinner wall
stuff with acceptable results.
Just fishing for ideas... wasn't sure if anyone had any experience
with micro-welding.

John Steck,
Way too low amps for what we use Tig's for.Can you fold and crimp and
use spot welder?. .002 wall is tissue paper.
