摘要
A plasma gun has a hollow generally cylindrical anode nozzle member and coaxially disposed therein a cylindrical cathode member, the members co-acting to form an interior passage for plasma forming gas. At one end, within the body of the gun, the passage comprises an annular gas inlet chamber or plenum proximate to the cathode. Progressing in the direction of flow, the passage is defined as an annular space between the cathode and anode members and then continues through the anode nozzle member to the exterior of the gun body. Plasma-forming gas is introduced inwardly through respective inlets, tangentially and radially into the gas inlet chamber. Means are provided for selectively regulating the respective amounts of gas introduced radially and tangentially to thereby determine the degree of vortical flow of gas through the gun.
