... in turn melts the end of the electrode, and the molten drops fall through the slag. Reaction of the molten drops with the slag removes sulfur and some other impurities, and the purified drops collect to form a molten pool on top of the starter plate. ESR melting typically is done at a higher rate than VAR...

... is generated by the passage of high current (usually alternating current) through the molten slag. As the end of the electrode melts, droplets of molten metal fall through the slag, are refined, and collect in a pool in the mold, building an ingot as the electrode is consumed. There are two basic variants...
