Plasma Arc Machining: Diagram, Parts, Working, Uses [PDF]
Plasma arc machining erodes materials using a high-temperature ionized gas plasma. This is a mixture of free electrons, positively charged ions, and neutral atoms. Plasma arc machining is a metal removal process in which the metal is removed by focusing a high-velocity jet of high-temperature (11,000°C to 30,000°C) ionized gas on the workpiece.
