Abstract: A DC arc furnace including a hearth adapted to contain a melt and having a melt electrode which is only effective when covered by the melt, an enclosure for the hearth including a roof over the hearth, at least one arcing electrode depending downwardly through the roof and adapted to initially melt a charge of solid metal on the hearth and thereafter the resulting melt, and at least one starting electrode through which electric power is transmitted to the charge of solid metal until it is melted down by the arcing electrode to enough melt to cover the melt electrode; the starting electrode or electrodes depending downwardly through the roof at a position horizontally offset from the arcing electrode and being adapted to be moved downwardly so as to press on the charge of solid scrap on the hearth until the charge is melted down by the arcing electrode so as to cover the melt electrode and thereafter to be moved upwardly free from the charge.
