Cutting electrode or burning bar having an oxidizable metal fluid conduit (tube) (12) surrounded by a mass of metal (14) similar to that of the fluid tube, the entire structure covered with an outer oxidizable metallic tube (16) and/or an electrically insulating water impervious cover, 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 workpiece and the free end of the electrode to produce a cutting flame. By proper selection of the type and mass of the materials of construction the electrode will burn after the electric current has been turned off. |
