Air Plasma Cutting Machines

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).Air is the most versatile plasma gas; it produces good cut quality and speed on mild steel, stainless, and aluminum. Air also lowers the cost of operation because it is not necessary to purchase gases.Nearly all plasma cutting systems fall under two categories: Conventional and Precision plasma systems. Conventional Plasma Systems - Typically use shop air as the plasma gas, and the shape of the arc is determined by the nozzle on the torch.
