Which welder to buy?

Miller, Hobart, Lincoln, ect most wirefeeds are all made by one company...Tweco. The only real difference is the gun and the fittings where the gun plugs into the welder. My personal preference is the Hobart handler 150 that runs on 220 with a 75/25 bottle that I have at work. At home I have a Millermatic 130 that runs on 110 and a 75/25 bottle but for any sheet metal/body repairs just get a good set of torches, rods and learn how to hammer weld! You don't have to get a super expensive set of Victor torches, you can goto Harbor Freight and get their set. There is no real difference between the Victors and the HF sets and the tips all interchange. The only real cost will be the bottles if you want to own your own or rent them from a supply house.
