Could anyone advise me on which amp stick welder I ought to buy. I will be mostly working on steel no thicker than 6mm and a chart I found recently gave me:- "Electrode Dia: 3.2mm / Amps: 105 - 130 / Metal Thickness: 4 - 6mm.
My question is: I have a 7kVA Inverter generator so what would be the optimum amp welder I could run from it (if nothing else was being run off it at the same time)?
Would 170 amp run comfortably? 140amp seems sufficient but would it be worthwhile getting the higher one for any unforeseen thicker metal jobs in the future?
Cheers.
