  • Patent number: 8357007
    Abstract: A cable assembly with strain relief for providing welding control is provided. One welding control cable assembly includes a cable having a plurality of conductors configured to convey data and/or power in an insulative jacket. The cable assembly also includes a retainer bound to an outer surface of the insulative jacket adjacent to an end of the cable and a connector assembly having a plurality of connector elements in a housing. Each of the connector elements is terminated to a respective one of the conductors. The housing is disposed adjacent to the retainer. The assembly includes an overmolded shell disposed over the retainer and at least a portion of the connector assembly. At least the insulative jacket, the retainer and the overmolded shell cooperate to resist stress on the conductors by axial tensile forces placed on the connector assembly.

  • Patent number: 8330077
    Abstract: Embodiments of a pendant associated with a multi-process welding power supply that allows a user to switch processes and reverse an output polarity while located remotely from a power supply unit are provided. Certain embodiments include a pendant with a wire spool and wire feeder drive circuitry that is configured to activate spooling during MIG welding. Control circuitry that may include processing circuitry and memory is provided. The control system may disable redundant controls on the power supply unit user interface when the power supply unit is connected to the pendant via a supply cable. Additionally, the control system may set the process, set the polarity, enable or disable a wire feed, and enable or disable gas flow according to inputs received via a user interface on either the power supply unit or the pendant.

  • Publication number: 20110284513
    Abstract: A welding torch with a welding electrode and a welding electrode holder is provided. One welding torch includes a securing mechanism and an insulated grip. The securing mechanism is configured to secure an exposed central portion of a welding rod bounded by flux covered first and second sides. The securing mechanism is also configured to make electrical contact with the central portion of the rod for arc welding with the first side. The insulated grip is configured to cover the second side of the welding rod.

  • Publication number: 20110284500
    Abstract: A method and system for detecting a welding gas leak is provided. One welding power supply includes a gas valve configured to control the flow of shielding gas to a welding device through a gas line. The welding power supply also includes a sensor coupled to the gas line and configured to detect a parameter of the shielding gas. The welding power supply includes control circuitry coupled to the gas valve and to the sensor, and configured to control the operation of the gas valve, and to receive device value representative of the detected parameter. The control circuitry is further configured to determine a leak test result based upon the parameter value, and to provide an operator indicator of the leak test result.

  • Publication number: 20110247999
    Abstract: A weld electrical and gas connector with sealed gas flow is provided. In an exemplary embodiment, a welding cable connector system includes a male connector having a conductive body for conveying welding power. The male connector includes a sealed passageway disposed coaxially of the conductive body for conveying shielding gas, and a gas sealing valve configured to seat to stop flow of shielding gas when the male connector is not engaged. The system also includes a female connector having a conductive body for conveying welding power. The female connector includes a sealed passageway disposed coaxially of the conductive body for conveying shielding gas, and a gas sealing valve configured to seat to stop flow of shielding gas when the female connector is not engaged. The male and female connectors are mutually engageable to conduct welding power and shielding gas therethrough.

  • Publication number: 20110073569
    Abstract: Various welding systems that provide communication over auxiliary or weld power lines are provided. The disclosed embodiments may include a multi-process welding power supply that is communicatively coupled to a pendant via an auxiliary conduit that facilitates the exchange of data and power between components of the welding system. In some embodiments, the pendant may also include auxiliary outlets that allow an operator to power auxiliary devices at the weld location. The disclosed embodiments further include a pendant with a wire spool and wire feeder drive circuitry that is configured to activate spooling during MIG welding. Embodiments are provided that also allow for bidirectional data communication over a power line in networked welding systems.
