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.
