Abstract
An exothermic cutting electrode or burning bar having an oxidizable metal fluid conduit (tube) surrounded by alternate layers of wire wound helically in opposite directions, the entire structure covered with an outer oxidizable metallic tube, either end of the electrode being adapted for connection to a source of oxidizing fluid and electric current, so that an arc can be struck between a work-piece and the free end of the electrode to produce a cutting flame. By proper selection of the type and size of materials of construction the electrode will burn after the electric current has been turned off.
