For the money this is a good machine, it doesn't come with a mains plug but the Nema 6 220v plug works fine, the yellow-green wire is the ground wire blue and brown are hot wires. At 110V the car didn't start, but at 220V it worked fine. The cuts aren't as clean as with Hypertherm or other plasma cutters, but they do the trick. Don't forget to get additional consumables, as you'll use them up fairly quickly. For $300 it does everything I expected from it. It cuts best at 40 to 60 psi air…
