So then I went to Lowes and bought a single non gfci 20amp outlet and installed it at my house. No improvement. This morning I went to harbor freight and bought a clamp meter, the video below is the machine just started up after no use for 14hrs running 140 amps on DC tig(meter hovers around 28-30 amps). Then I called ESAB support. Guy said for 120v welders 30amp breaker is needed. In my first post the picture shows the product manual says maximum recommended fuse/breaker rating 20 Amps. oh well.

    I was under the impression that code didn't allow an oversize breaker for some reason, but have a hard time finding 15 amp breakers locally. I was notorious for running 12 wire for 15 amp receptacles, but it is hard for me to get it wrapped around the screws, especially with my old decrepit hands. I di get ahold of some that wired from the back using screw clamps & really liked them, a little more costly, but hey, I've always been a little leery of the 49 cent cheapies.
