I have a Chinese eBay (Smiley Mitech etc) 220v 30A welder model MTC 120 (rear label says TIG312T). It's missing the potentiometer and i can't for the life of me find any kind of electrical diagram. I'm hoping someone on this forum has one or maybe a similar model (CT312) and can look at the heat knob pot value and where it's connected.
