I'm having my panel replaced soon since it's an old PFE and will get a few 20amps installed in the garage... the panel is right outside of the garage. Then I'll do my welding in there.Absolutely correct. Same problem with my Hobart Handler 140, 120volt wire feed welder. The gauge of the wire and length of run make a huge difference in weld quality and welder performance. The shortest 10 gauge extension cords possible and as close to the electrical panel too.
