Abstract
A method of producing electrode units for plasmatrons, according to which a direct-current arc is struck between a tungsten electrode and a melt, so that the electrode acts as a cathode, prior to dipping the electrode into the molten metal, intended e.g. for an electrode holder. Then the electrode is dipped into the melt, and the arc is extinguished.
