ABSTRACT:
A method and means for more efficiently stabilizing a plasma arc produced within a plasma producing device. Improved arc stabilization is achieved by dissipating the heat generated by the electrodes of the plasma producing device under controlled conditions. This is achieved, in one instance, by direct liquid cooling of the anode and concomitantly therewith indirect liquid cooling of the cathode. The latter is achieved by passage of a liquid coolant around a heat sink positioned in conductive relationship with the cathode. To further insure controlled heat dissipation and thereby maintain a preselected cathode temperature profile, the plasma forming gas, as well as the liquid coolant, are introduced into the plasma producing device in a manner and at a rate such that the tip of the cathode is maintained at a temperature just below the cathode's melting temperature, the central section of the cathode is maintained at or near the cathode's oxidation temperature and the rear or base section of the cathode is maintained at a temperature below the cathode's oxidation temperature.
