  • TIG WELDING SYSTEM AND METHOD
    Publication number: 20110303647
    Abstract: The invention provides a welding arrangement designed to respond to the need of an improved welding system that aids in supplying filler material to a weld location. Provided is a welding system including a welding gun and a welding wire feed directly coupled to the welding gun. The welding gun includes a filler material housing, a filler material positioning extension, and a manual advancement device configured to advance a filler material through the welding wire feed. Further provided is a method of operating a welding gun. The method includes passing a current between an electrode and a work piece at a weld location, and advancing a filler material toward the weld location via a channel of a positioning extension in response to engagement of a manual advancement device.

  • Method and apparatus to adaptively cool a welding-type system
    Patent number: 7381924
    Abstract: A cooling system connected to provide coolant to a welding-type component automatically circulates coolant through the welding component upon activation of the welding component. A controller is configured to regulate the cooling system such that upon activation of the welding-type component coolant is caused to at least flow through the welding-type component, and circulate after deactivation of the welding torch until a temperature of the coolant falls below a certain value or a specified time period has expired. The cooling system is constructed to be integrally disposed within a power source housing.
