<p>CUTTING AND GOUGING HEAD FOR WELDING EQUIPMENT A head attachable to the insulated handle normally used to support an electrode employed in electric are welding. The head supports a particular 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 an annular stream enclosing the electrode and travelling longitudinally thereof to impinge on the workpiece and blow away molten metal at the tip of the electrode.</p> |
