You didn't swap ground-clamp from black terminal to red terminal when you switched from stick to TIG welding did you? Aiming -neg torche electrode to -neg workpiece would result in ZERO current flowing because there's no voltage-differential.

No I kept the Ground in the same terminal.... but the machine just didn't work.... it worked great for stick welding, I welded aluminum stick welding on the bark busters on the Kids bike that I busted by falling over trying to start that tall thing..... ( t'was quite embarrassing!) but I did weld it up and fix it nicely.... it's stronger than the other one now !

Maybe my next welder will work the way it is supposed to !
