PLASMA CUTTING

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