  • Patent number: 4161642
    Abstract: A head attachable to the insulated handle normally used to support an electrode employed in electric arc welding. The head supports an electrode and combines with the handle to provide a torch which allows cutting and gouging to be performed by conventional welding equipment. A conductive body of the head electrically connects the electrode to the handle and compressed air is delivered through the body to a jet nozzle on the end of the body in which the electrode is adjustably mounted. The air discharges from the jet nozzle as a stream which travels longitudinally of the electrode to impinge on the workpiece and blow away molten metal at the tip of the electrode.
