@smellsofbikes @ClaraListensprechen@universeodon.com Modern electronic welders like mine do fine on lighter metal, up to 1/8". Running on 120V it delivers up to 85 amps. I usually run it on 240 but I used it on 120 until I installed a 240 feed for it. To change input voltage you just put an adaptor on the plug. It runs on anything from 100 to 250 volts.
