Modifying small TIG welder


#1

I want to weld silver and gold (not tack weld requiring additional
soldering, but permanent welds similar to a laser welder). I can not
afford a laser welder.

Other types of jewelry welders cost $2000 - $4000 (Puk III, ABI,
Tack, etc.).

Is is possible to use or modify a small TIG welder to weld gold and
silver? These can be had to $400-500.

Any DC TIG welder can weld gold or silver. The question is how small
a torch you can get and how precisely can you control the current. I
have not seen any $400-$500 welders with any kind of precision
control, for $1500-$2000 you can get a nice small inverter welder
that has adequate control but fro real precision you are talking
$3000-$4000. A Weldcraft micro torch will cost another $250 then you
should be set to weld on jewelry scale items. I have found gold to
be fairly easy to TIG weld but silver is tricky. There is a paper in
the 2006 Santa Fe Symposium by Kevin Lindsey

on TIG welding jewelry. He has some good tips. You can get the
proceedings of the symposium from Rio Grande
