I am new to this forum and do not weld for a living. I have several mechanical hobbies and inevitably need to weld from time to time. I have done a little stick (arc) and gas welding over the years. Some in a welding class and some outside, but only have a OxyAcet set. I need to weld some 1/8" mild plate at the moment but also do some body work (sheet) and would also like to be able to weld 4130 steel tube and maybe aluminum down at some point. I think its finally time to buy a wire welder. Would MIG suit for all this? Any suggestions for best setup (model, key accessories)? I understand Miller/Hobart is a good choice, but that something above the bottom of the line many be a wiser way to go. Any guidance and wisdom would be much appreciated.
