| 20080230529 | Wear-resistant welding contact tip - The present invention discloses novel metal compositions predominantly composed of copper, nickel or nickel-cobalt, and tin for use in Mig welding and other application methods to form electrically conductive, oxidation resistant, and wear resistant welding contact surfaces. | 09-25-2008 |
| 20080272101 | WELDING CONTACT TIP WITH CONDUCTIVE BRUSH - A contact tip is provided for wire welding applications. The contact tip includes one or more conductive brushes fitted to a conductive contact tip body. Fibers of the brush extend into a passageway traversed by welding wire in operation. Electrical current is transmitted to the brush assembly and through the brush fibers to the welding wire. The fibers may transmit the current directly and also may enhance contact of the welding wire with one or more walls of the contact tip. Improved electrical contact and weld quality are obtained. | 11-06-2008 |
| 20090152255 | RETAINING HEAD AND CONTACT TIP FOR CONTROLLING WIRE CONTOUR AND CONTACTING POINT FOR GMAW TORCHES - A retaining head for a MIG welding device includes a contact tip mounting end, an opposite retaining head mounting end, and a throughbore extending from one of the ends to the other end. A deflector is disposed along the throughbore and is adjustable for imparting a bend in welding wire passing through the throughbore. The deflector provides a straight wire contour for the welding wire that is fed out of the welding torch, while maintaining sufficient contact force between the welding wire and the contact tip. The deflector also reduces the effect of wire twist on the contact point between the welding wire and the contact tip. | 06-18-2009 |
| 20100176109 | METHOD AND SYSTEM TO START AND USE A COMBINATION FILLER WIRE FEED AND HIGH INTENSITY ENERGY SOURCE - A method and system to start and use a combination wire feed and energy source system for any of brazing, cladding, building up, filling, and hard-facing overlaying applications. High intensity energy is applied onto a workpiece to heat the workpiece. One or more resistive filler wires are fed toward the workpiece at or just in front of the applied high intensity energy. Sensing of when a distal end of the one or more resistive filler wires makes contact with the workpiece at or near the applied high intensity energy is accomplished. Electric heating current to the one or more resistive filler wires is controlled based on whether or not the distal end of the one or more resistive filler wires is in contact with the workpiece. The applied high intensity energy and the one or more resistive filler wires are moved in a same direction along the workpiece in a fixed relation to each other. | 07-15-2010 |
| 20110006048 | REFRACTORY MATERIALS REINFORCED COMPOSITES FOR THE GMAW CONTACT TIPS - A contact tip for a welding torch includes a refractory material reinforced copper composite including approximately 10 to 50% by volume of a refractory material and at least one of copper and a copper alloy. The refractory material is one of a metal and a ceramic material. The contact tip may include an elongated, generally cylindrical body having a front contact end, an opposite rear retaining end, and a passageway extending from the rear retaining end to the front contact end. A portion of the passageway may be defined by the refractory material reinforced copper composite. The portion may have a diameter that is approximately 3 to 8% larger than an outer diameter of a consumable electrode wire, and the portion may have a length of approximately 0.2 to 0.6 inches. | 01-13-2011 |
| 20120125904 | WELDING NOZZLE - An exemplary welding nozzle has a smooth, highly polished bore of circular cross-section. The bore has a forward portion of generally flared, gradually curving shape, joined with a narrowing inner portion along a gradual curve. Hence a concentrated surface flow of shielding gas may be directed out the nozzle's mouth to reliably provide a flared shielding envelope having reinforced boundaries. The inner portion tapers inwardly at a constant angle for a length sufficient to dampen flow disturbances. Hence an inner core of shielding gas of high ionization potential may be directed in laminar flow out the nozzle's mouth for concentration immediately about the exposed electrode to stabilize the electric arc at the electrode tip. The diverging gas flows enable significantly reduced gas consumption while reliably maintaining weld quality, a reduced rate of spatter buildup within the nozzle, and increased versatility of welding tip operation in both automated and manual environments. | 05-24-2012 |
| 20140251972 | Replaceable Machine-Mounted Male Input Power Connections - A system and method for replaceable machine-mounted male input power connections includes a power connection unit that is at least partially arranged within a housing and configured to transfer power received from a power source to drive a welding process. The power connection unit includes an input configured to receive power from the power source, an output configured to deliver the power received at the input to drive the welding process, and a bus system, configured to connect the input and the output. The power connection unit also includes a male connector having a conductive post extending to a threaded cylindrical shaft. The male conductor forms at least a portion of the input or the output and extends from the housing through a coupling assembly. The coupling assembly includes a correspondingly threaded portion configured to engage the threaded cylindrical shaft of the male connector to the bus system. | 09-11-2014 |
| 20150136748 | POSITIONING SYSTEM AND METHOD FOR ARC WELDING CONSUMABLES - A nozzle assembly for a welding torch, a welding torch that includes said nozzle assembly, and a method of using the welding torch is provided. The nozzle assembly generally comprises an insulator having a plurality of grooves around an outer periphery, a plurality of sealing members disposed within the grooves of the insulator; and a nozzle body slip-fit around the insulator, such that at least one of the insulator and the nozzle body define position indicia. | 05-21-2015 |
| 20150136749 | SYSTEM AND METHOD FOR MATCHING ARC WELDING CONSUMABLES - A consumable assembly for a welding torch, a welding torch that includes said consumable assembly, and a method of using the welding torch is provided. The consumable assembly generally comprises a nozzle body having an exterior surface and an internal bore; and a contact tip having an exterior surface that is removably disposed within the internal bore of the nozzle body. The exterior surface of the nozzle body and the exterior surface of the contact tip include matching indicia for pairing the nozzle body with the contact tip. | 05-21-2015 |
| 20160121419 | Replaceable Machine-Mounted Male Input Power Connections - A system and method for replaceable machine-mounted male input power connections includes a power connection unit that is at least partially arranged within a housing and configured to transfer power received from a power source to drive a welding process. The power connection unit includes an input configured to receive power from the power source, an output configured to deliver the power received at the input to drive the welding process, and a bus system, configured to connect the input and the output. The power connection unit also includes a male connector having a conductive post extending to a threaded cylindrical shaft.

| 20160129523 | ELECTRICAL CONTACT FOR MIG WELDING TORCH - A contactor providing for electrical contact in a welding torch includes a body member having first and second opposite sides, and adjacent pivot and head portions. The pivot portion has an outwardly curved contact surface on the second side providing a pivot point. The head portion also has a contact surface on the second side. The pivot portion has a shorter length between the first and second sides than the head portion. The contactor may be pivotally mounted in a torch connector body. At least one resilient member urges the contact surface of the pivot portion into engagement with an inner flange surface of the connector body, and biases the head portion into an opening in the torch connector body. The contact surface of the head portion is engageable with a torch neck inserted into the torch connector body, and provides an electrical connection between the torch body and neck. | 05-12-2016 |
| 20160144446 | CONTACT TIP AND RECEIVING ASSEMBLY OF A WELDING TORCH - A method to replace a contact tip in a welding system includes applying a first force toward a neck of a welding torch to remove the contact tip via a quick release mechanism.
