Abstract

Method for supplying molten by wetting in the form of a cordum onto a metal piece, using a main arc between a main electrode and the metal, and a secondary arc formed by current drawn from the first arc towards a secondary electrode, the axes of the ends of the electrodes converging at a point closed to the surface of the metal piece, is claimed in which equilibrium is maintained between the two arcs by permanently controlling the distance between the point of convergence of the electrodes and the electrodes and the metal surface, by controlling the position of the electrode support in association with a constant supply of current to the principal arc. Fluctuations of operation due to arc fluctuations are counteracted.
