FIELD: electric metallurgy.
SUBSTANCE: method comprises control of parameters of arc and power source by imposing pulsations to the total arc current and supplying pulsating flux of plasma-generating gas to the interelectrode space through the axial opening in the arch electrode. The frequencies of the pulsations of the arc current and the flux of plasma-generating gas range from 0.1 Hz to 10 Hz.
EFFECT: enhanced quality of melting.
