Trindl Thermotron has two settings, 200amp and 300amp
200 amp setting puts out AC voltage at 3volts, 300amp setting puts out 6volts AC.
have seen all sorts of funky setting on welding forums including reports of fires. safer to rent one instead of using a welder. unless you are able to duplicate spec's above.
