For sale is a Miller Dialarc HF Welder. I have tested it and it works pretty well. What is really stupid is that it has two cables (for ground as well as stinger), but both of them have ground clamps. You can buy a stinger at Harbor Freight for $7.99. It also comes with a TIG torch, TIG pedal, etc. I have tested it -- tried to stick weld -- it works great. It also has a running gear.
I also have a (not included) Miller Radiator-1 TIG torch cooler. I will let you buy it cheaply if I still have it and if you need it. Free pickup for casn in Berkeley, IL, 60163.
