Hi guys i am stumped cause my Miller Dynasty 280 TIG arc wanders off steel at 120 amps, And it drifts bad. Any tips?

Wandering arc is from a bad ground. Check clamp for corrosion, And use 3/32-inch tungsten. my arc stayed focused after that. Clean with alcohol, And set 25 CFH argon.

Check AC balance, my Dynasty welds smooth at 70%.

Use a sharper tungsten grind, It gives better control.
