Going to start bodywork and will need to do some welding. Friend of mine has loaned me a welder. Its a Hobart Handler 135 (MIG?) with a CO2/Argon mix shielding gas. Have read the instruction book and about all it says is " these instructions are parameters only, you may have to adjust to suit your conditions". I think I can do this but am I being overconfident? I can do oxy/acet fairly well but I guess this system should not be used for bodywork because of the excess heat and warpage that might result. So what say you? Jump right in? Practice? What? Weeds
