A computational experiment was conducted which showed that the controlled electrical parameters of the process can be used to regulate the shape of the metal pool and electrode melting rate. Dependencies between the depth of electrode immersion into the slag pool, average depth of item penetration and uniformity of item penetration relative to average penetration depth were determined. A method was proposed for computation of the depth of electrode immersion into the slag pool by the ratio of currents in CSM. Comparative analysis of the three types of single-loop circuits of the mould connection to the power source was performed, and an optimum circuit for the required criteria of surfacing quality was proposed. 8 Ref., 1 Tabl., 12 Fig.
