TIG on a MIG machine
Awhile ago I found an excuse to finally but the mig machine I'd wanted.
Found a way to convert it to tig, just
don't have high frequency to do aluminum, but the hi freq is available
as a stand alone unit.
Need different gas (argon is best like
for stainless) and a "tig rig" but it's
easy to convert the power source which is the main expense.
I think I've got a simple schematic
I drew up if anybody is interested.
