ABSTRACT:
A process and device for cutting an electrically conductive workpiece. The workpiece is moved relative to an endless circulating electrode while an electrical voltage is applied to the electrode and the workpiece sufficient to form an arc therebetween for melting the material of the workpiece, which melted material is then carried away by the circulating electrode. The electrode may also oscillate in the direction of relative movement and/or the electrical voltage may be interrupted at certain times such as when the electrode is operable to carry away the melted workpiece material.
