    I'd like to have a plasma cutter but they're beyond my budget. Does anyone know how to make one?

    This YouTube video shows someone using a homemade plasma cutter they built for around $260:

    However, there is a very dangerous safety issue with the schematic; no isolation from mains power.

    A transformer should be used. I don't know where to find one of sufficient power handling capability offhand.

    i love plasma cutters, they are amazing. I've used one a few times now, it ceases to amaze me how they cut through steel with no physical resistance you would get using a saw. It just feels odd. Plasma cutters while simple in design, are quite technical in the way they work.
