If you ever have any welding questions shoot me a pm I'd be happy to help if I can I live south of Olathe/Overland Park KS about 20 minI appreciate the links and I will certainly be viewing them. I will say after switching from my HF 90amp to a Hobart 140, well, the welder really was a lot of the problem. I also installed a dedicated circuit for the Hobart. It was such a big difference I actually went back and ground the welds from my seats and re welded with the Hob.
