Co to jest? Technologia Arc Plasma?

Fundamentals of Plasma Generation

Plasma arc technology creates a high- temperature plasma jet passing an electric arc through gh a gas. When a direct terrant (DC) or alternating current (AC) arc strikes between two electrodes, it ionizes the carrier gas - common argon, nitrogen, or a mixture of hydrogen and argon - into conductiva straim of ions and controlles. Thee resumping plasma reaches tempertures rang frem 5,000oC to over 20,000o C, far execing the meltics of of.
