This has been very helpful all the way around and I wanted to say thank you. One last question, I have decided when the money does becomes available and I do get a "MIG" it will be a bare wire system. WAY back in the 70's when I was taught how to weld we used pure Argon.......I now hear of CO2 as well....maybe even a mix of inert gases are best to use. Is there one gas that works well in all cases or are certain gasses or a mix needed for certain metals etc?
