The nozzle insert includes an internal gas diverter. A contact tip is disposed within the nozzle assembly and includes at least one aperture extending from an exterior portion to an internal cavity, an exit orifice, a distal end face, and an exterior surface extending between the at least one aperture and the distal end portion of the contact tip. The internal gas diverter directs a flow of shield gas exiting the at least one aperture along the exterior surface of the contact tip. | 05-14-2015 |
20150129572 | HIGH PERFORMANCE CONTACT TIP AND NOZZLE ASSEMBLY FOR AN ARC WELDING APPARATUS - A consumable assembly for use in an arc welding apparatus is provided that includes a nozzle assembly having a nozzle body, an insulator disposed within the nozzle body, and a nozzle insert disposed within the insulator. The nozzle insert includes an internal gas diverter. A contact tip is disposed within the nozzle assembly and includes at least one aperture extending from an exterior portion to an internal cavity, an exit orifice, a distal end face, and an exterior surface extending between the at least one aperture and the distal end portion of the contact tip. The internal gas diverter directs a flow of shield gas exiting the at least one aperture along the exterior surface of the contact tip, and a principal distance from the at least one aperture to the distal end face is varied to adjust the flow of the shield gas for improved cooling. | 05-14-2015 |
20150135796 | TOOL AND METHOD FOR REPAIRING AN ARC WELDING TORCH - A tool for repairing an interior surface of a conductor tube comprises an elongate body having a proximal end and a distal end. The tool includes a profiled end surface that mates into the interior surface of the conductor tube. The tool includes a central protrusion that extends from the profiled end surface for aligning the tool within the internal passageway of the conductor tube. An imparted force is exerted on the proximal end and the force reshapes the interior surface of the conductor tube around the profiled end surface. | 05-21-2015 |
20150136747 | CONNECTOR FOR ARC WELDING CONDUCTOR TUBE FOR GMAW MANUAL/ROBOTIC ARC WELDING MIG GUNS - An arc welding apparatus comprises a conductor tube defining an internal passageway is disclosed. The conductor tube further defines an external surface profile and a distal end portion. The conductor tube is configured to engage a sleeve having inner and outer surface profiles. The inner surface profile is configured to abut the external surface profile of the conductor tube, and the outer surface profile comprises an engaging portion. | 05-21-2015 |
