ok there is something defiantly wrong.....it just holds the HF arc for ever. It will be HF arcing and after 30 seconds decide to start the welding arc. Sometimes less sometimes more. I cleaned the ground, adjusted gas preflow to zero, tried a different torch, super sharpened tungsten, and it still does it with the pedal floored. The AC lights up right away, but the arc is wandering all over the place and makes a loud snapping, clicking noise. I think the unit got goofed in shipping.....I bummed out, I really needed this machine to start some work. Would the point gap cause any of this? I see the HF arc it just won't start welding.....(only when it wants). Oleg I'll call you in a couple hours
