I have long wanted to learn the art of MIG. I am leaning real hard towards a passport. Anyone here have one or know of this model ? Good, bad, indifferent I'd like to hear what you have in regards to this or for that matter any other MIG welder. I'd like the option to be able to handle up to 3/8" but most times it will be 1/4" or less. Smattering of alum possibly and maybe SS once in awhile.
