This could be a great TIG welder but the problem I have is that the description says TIG compatible with a foot pedal but I couldn't find it anywhere. I even called SSC Controls (a company that specializes in control pedals for welding machines) and they said they couldn't make a pedal. Without current control during welding, it is extremely difficult to produce quality TIG welds. For this reason I do not give this welder a high rating. I will get mine back, 2 weeks of calling and trying to contact tech support or sales with zero success.
