harbor freight has a DC GTAW welder for $350 before tank and regulator... I am saving for a Miller Dynasty 200DX. I am in welding school and have been GTAW welding for about a year and have been able to make some beautiful welds on mild steel, stainless, and aluminium...GTAW is definitely my favorite process of them all. And if you can weld with oxyfuel then GTAW will be easy. I have also welded Mig and am takeing my last course in overhead SMAW welding and Prep for Industrial Qualification starting in January.
