I have aqqired a Weldcraft TIG 3500SSB 115V 5.4A Single Phase Welder (w/water holding tank and circulator) from a friend of mine. It was found in the corner of a shop not doing anything but taking up space. I would like to use it for sheet metal on my Minitruck. It came with tourch, cables, hoses, Argon Guages and Regulator. I would like to know if this is even worth my time. Can I weld sheet metal with it. What else may it be able to weld. Perhaps even how to use it. There is no swich, pedel or other trigger for electic or gas on/off. Does anyone know anything about this particular machine or any other Weldcraft product. I can't find any information on anything from Weldcraft anywhere. Please help me shed some light on this welder for me.
