Studied was a nature of change of electro-technical parameters of process of discrete filler melting in its portion feed in a stationary current-supplying mould. It is determined that the process of melting in a slag pool is effected by initial values of depth and specific electric conductance of the slag pool. Initially set average thermal level of the slag pool and stabilization of the process can be provided by means of correction of power source voltage. The method was proposed for selection of optimum position in the current-supplying mould of surface of part being deposited depending on used working flux. Ref. 5, Tabl. 1, Fig. 5.
