red or blue welder.
I looked at new welders, and used. found a used miller syncro 250 with water cooler but it was all apart. I was there with cash, my truck with the lift gate, and said I had to weld with it first. to call me back when I could weld with I. . No return calls, then found a Lincoln 255 Sq wave with water cooler, and hand control, It's a good tig welder, for about 20% of new cost. the only thing I don't like is I have to disconnect the tig cables and bolt on the Arc stinger cable and CANNOT arc with High frequency. My Airco AC DC has plug in connectors, Hi freq, that I almost always have on, repairing a lot of rusty or painted Farm and construction equipment, after a while I think I need one of everything, lincoln ac buz box, Lincoln trailer mounted gasoline powered, suitcase mini wire feed, spool gun, etc.
