Air Plasma Cutting Machine

Plasma cutting (plasma arc cutting) is a melting process in which a jet of ionised gas at temperatures above 20,000°C is used to melt and expel material from the cut. During the process, an electric arc is struck between an electrode (cathode) and the workpiece (anode).The basic principle is that the arc formed between the electrode and the workpiece is constricted by a fine bore, copper nozzle. This increases the temperature and velocity of the plasma emanating from the nozzle. The temperature of the plasma is in excess of 20 000°C and the velocity can approach the speed of sound.A “CNC plasma” system is a machine that carries a plasma torch and can move that torch in a path directed by a computer. The term “CNC” refers to “Computer Numerical Control”, which means that a computer is used to direct the machine's motion based on numerical codes in a program.
