GTAW Arc Start issues
(OP)
I could use some help, We have several automated tig weld machines, they apply a tack weld through formed stainless steel sheet, it is 409 ss, no filler material, using 100 Ar shielding gas, we have discussed this will the weld machine manufacturer and they advised attaching a ground lead to the ceramic cups to dischage any built up charges, set gas flow to bewteen 15 to 40 CFH.(searching for a magic flow rate) We still see the problem however it is intermittant.

You may wish to use the "touch-lift" starting method with controlled current ramp up instead.
