And i said it as a joke...
home made plasma cutter...lol
Lets use a gas engine to run a car alternator then take some parts out of a washing machine to build a so called TIG welder or Plasma cutter....
OR you could plug a cord in the wall and turn on a regular machine that cost a few hundred more and has a much better user interface, not to mention it comes in a box and doesnt have exposed wires and PVC parts!
I like there creativity but cut the
and buy one someone paid some smart engineers to design!
