You need to read my post againAbout 12 years ago I was doing a lot of welding, especially on farm equipment and farm related projects. I had a Lincoln stick and a 110 volt MIG welder. I also had a Hobart plasma cutter. They all worked well but I haven't used any of them in years. They're out in the shop covered with a tarp. If I was to do it again I would take Bob's route and get something cheap. I might even just get somebody to do the welding for me but where is the fun in that.
I used to have a friend that built motor cycle frames for drag racers. I would watch him work and be totally amazed at the quality of bead that he could get with his TIG set up.
