Abstract
Experiments in stationary and mobile current-carrying mould were made for study the effect of slag pool depth and adding of single portions of working flux into it on the surfacing current change. It was established that the increase in volume of slag pool in the stationary current-carrying mould is not a technological procedure of increasing its temperature at the power source unchanged voltage value. A single adding of working flux in surfacing in a mobile mould can only effect for a short time on value of operating current with subsequent its decrease to the initial value.

Key words: stationary and mobile current-carrying mould;; depth of slag pool; single flux adding;surfacing current
