Plasma Cutting, also known as Plasma Arc Cutting, is a process that uses super-heated, electronically ionized gas (the plasma) to cut through a piece of metal. The plasma arc is created by compressed gas being blown, at high speeds, through a focused nozzle. An electrode near the nozzle creates ionization of some of the gas and produces an electrically conductive plasma channel. The electricity traveling down the plasma creates heat to melt through the metal, thus cutting it. This method is useful when cutting metal in a curved or angled shape.
