I want a MIG welder. I want something with more finesse and control for thinner material and easer cleanup. I would like to be able to weld at least 3/16 to ¼ with it and also use it for sheet metal as thin as 22 gauge. I have 110 and 220 in my shop so voltage is not an issue. And I have my own gas bottles so that is not an issue. What models seem to be performing well and have a good warranty?
