Learning to weld has been… interesting. Although I did find the appropriate pedal control for the TIG welder on Ebay in China, it turns out the pedal doesn’t work the same way as it does on an American-made welder. On a Lincoln TIG welder, for example, you use the front-panel controls to set both the minimum and maximum power and then the pedal moves within that range. On my Chinese welder, the current settings on the front panel are disabled by connecting the pedal and the pedal control range is always from zero to 200 Amps. Maybe this works OK for welding structural steel, but it’s not so wonderful for welding Coke cans. Or race car chassis, for that matter.
