Plasma arc cutting is a metal cutting
process that uses a high temperature, high velocity stream of ionized
gas to melt and blow metal from the line of cut.
Process Characteristics
Is used primarily for ferrous and nonferrous metals
Produces temperatures up to 60,000°F
Cuts at high speeds with good accuracy
Uses an inert gas to form plasma, which also serves
as a shielding gas
Requires a cooling system for the torch and
sometimes the workpiece
