Well finally got my old Matercraft (Century built) 75 amp mig welder to run .024 solid wire,thanks to you guys for all your help. I want to do some patch work on my vehicle(s). This welder only has High and Low heat settings and adjustible wire feed. Ohhhhh ..... also I only have C02 gas that i use for carbonating my Homebrew. I was told that should be fine for what I'm doing,So can anyone tell me a happy medium where to set the gas on the regulator? (psi) it's around 12 now..... and Temp.setting on the welder to get me started ?....... Not a welder by any means. I've tried Low heat and all i get is pulses ........ High heat to get the buzz sound ..... but still seems to be too hot and of course i burn through......I've read where you should only spot weld every inch or so to keep heat from warping ..... Any suggestions from the pros would be appreciated. Thanks in advance.
