  • Patent number: 7347350
    Abstract: In accordance with one embodiment of the present application, provided is a welding support structure arrangement to support an elongated assembled weldment preparatory to positional welding. The arrangement includes at least one support structure having a support base and a movable platform connected to the support base by spaced-apart 2-bar linkages with center pintels and a series of length adjusting members between the pintels and the support base. A length adjusting member is located between the movable platform and the support base, wherein the lengths of the length adjusting members set the orientation of the movable platform. In accordance with another embodiment of the present application, welding support structures are arranged in a linear array, wherein each of the welding support structures include a movable platform. At least some of the movable platforms of the plurality of support structures are moved to predetermined orientations.

  • Publication number: 20070056934
    Abstract: A stud welding apparatus includes a power supply and a stud welding tool having a welding head portion and a cable receiving portion. A composite cable having first and second ends is coupled at a first end to the stud welding tool at the cable receiving portion and to the power supply at the second end of the composite cable. If the stud feeder is present, the second end of the composite cable can be coupled to the stud feeder. The composite cable includes a conductor having no individual electrical isolation and at least one control lead electrically isolated from the conductor. The conductor and the at least one control lead are surrounded by an outer non-conductive layer.

  • Patent number: 7100863
    Abstract: A floating liner for a container of welding wire which floating liner includes a tube having two ends and a passageway extending between the two ends. The floating liner is unsupported between the top of the container and the retaining ring. The floating liner is designed to provide structural support to the wire and added stiffness or rigidity to the wire to inhibit buckling of the wire, knot formation in the wire that can form between the retaining ring and the top of the container. The floating liner has a weight profile that causes one end of the tube to at least partially float above the top surface of a layer of welding wire or retaining ring in the container as the welding wire is paid out of the container.

  • Patent number: 7067767
    Abstract: An electric arc GMAW welder is provided, which welder includes a high speed switching power supply with a controller for creating a first or second weld process across the gap between a workpiece and a welding wire advanced toward the workpiece. The first process uses a first current waveform and the second process uses a second current waveform. A circuit is provided for shifting between the first and second weld processes. The shifting circuit includes a counter for counting the waveforms in the first and second processes and a circuit to shift from the process being processed to the other weld process when the waveform count of the weld process being processed reaches a preselected number for such weld process.

  • Publication number: 20060102505
    Abstract: A package for containing and dispensing wire from a coil of welding wire. The package having an outer layer with a bottom and an outer side wall having an upper edge defining a box opening for removing the wire from the package. The package further including an inner core positioned within the inner cylindrical opening of the wire coil wherein the inner core has a base supported by the package bottom and an oppositely facing core top. The core base being generally maintained relatively to the package bottom to prevent the core from “walking-up” the wire coil and the core top being allowed to tilt as the wire exits the package.
