TIG (GTAW) welding copper sheet 3

[kristof]

what are the conditions and filler metal I would need to TIG weld copper sheet of 0.5 - 1mm thichness?
Would a DC TIG machine, 140 amp max, be suitable? Argon or helium?

Try this:

No root opening
1/16" EWTh-2 electrode
no filler metal
Argon gas at 15 ft3/hr
100 Amps
12 in./min travel speed
no preheat
one pass

evaluate results and tweek from there.
