Metal Cutting is a process that is used to cut steel and other metals of different thicknesses(or sometimes other materials) using a plasma torch. In this process, an inert gas (insome units, compressed air) is blown at high speed out of a nozzle; at the same time anelectrical arc is formed through that gas from the nozzle to the surface being cut, turningsome of that gas to plasma. The plasma is sufficiently hot to melt the metal being cutand moves sufficiently fast to blow molten metal away from the cut.
