Abstract
An electrode for use in cutting or gouging workpieces underwater by means of an electric arc comprising a generally elongated porous substrate, with a circumferential recess proximate one end to form a snap-off end on the substrate. The substrate is covered with a combined electrical insulating and waterproof coating except for a portion of the end opposite the recess which is inserted into a suitable underwater torch. When the electrode is submerged it has complete waterproof integrity until the snap-off end is removed to allow the substrate to be brought in contact with the workpiece so that an arc may be struck and maintained between the substrate and the workpiece to achieve cutting or gouging.
