I see all these posts about mig and tig and so on, I do not know what they mean. I have a Speigel 70 amp 110 volt machine that Dad bought used in I think 1959 that I learned to weld on, I also have a 225 Amp AC lincoln that I used to be able to do decent on flat surface welding when I could see better. About 15 years ago I would guess I bought a new 110 volt wire welder that I only ran one 2 pound coil of wire through because I could not get it to work. Do not remember the brand. It has no provision for a gas of any kind. Now the main question is what is this, a mig, tig or something else?
