Basic explanation - plasma arc cutting:

 Plasma arc cutting is a process where pressurized air is forced through small holes to form a rotating vortex inside a plasma cutting torch. This vortex is then electrified to ionize the air and superheat it to 15,000 + degrees Fahrenheit. This heating causes the ionized air, now called plasma, to rapidly exit the vortex chamber through a very small hole in the plasma torch cutting tip. This escaping plasma forms a tiny hot tornado, which when positioned properly above the surface of light gauge sheet metal, removes a narrow pathway of metal in any direction the torch moves.

 Plasma arc cutting is a non-contact process, meaning, the only thing touching the sheet metal during the cutting process is the tiny hot plasma tornado. The width of the plasma cut pathway is around .030 of an inch when cutting sheet metal.
