New old tig welder for newbie to tig
Hi. I have been welding with stick and mig for 34 years. I just recently bought my first TIG welding machine: a Miller 330A/BP.

Millermatic 252 Cuts out
Our Millermatic 252 cuts out after 3-4 seconds. You have to release the trigger and it starts back up for 3-4 seconds then drops out - rinse repeat

What am I doing wrong?
I've been using my airco 300 to fab an adapter for my lawn tractor. Most of the material is 1/4" steel bar. I've been using somewhere in the range of 200 amps.

Miller Legend: Is a bad brush the problem?
Just picked up an old Miller legend that runs great but doesn’t produce power. Diodes are good fuse is good rectifier is now good. The only thing I found was one of the brushes was bad ( wire broken from brush to contact), would one brush being bad cause no output power on generator and welder?
