A plasma torch (or plasma arc or plasma gun) is a device for generating a directed flow of plasma. The plasma jet can be used for applications including plasma cutting, plasma spraying, and plasma arc waste disposal.
Thermal plasma DC torches
Thermal plasmas are generated in plasma torches by direct current (DC), alternating current (AC), radio-frequency (RF) and other discharges. DC torches are the most commonly used and researched, because when compared to AC: “there is less flicker generation and noise, a more stable operation, better control, a minimum of two electrodes, lower electro...
