Christopher J. Wierschke has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Welder generator engine speed control
    Patent number: 9604302
    Abstract: An engine-driven welder generator is controlled based upon power draw for welding and other applications. Once a welding arc is initiated, the power draw is monitored. The engine speed, and therefore the power output of the generator, may be increased or maintained based upon the power draw. The power draw may include both welding power draw and auxiliary power draw. The engine speed is increased in increments. The initial engine speed and subsequent increments may depend upon particular welding processes or regimes.
    Type: Grant
    Filed: January 29, 2016
    Date of Patent: March 28, 2017
    Assignee: ILLINOIS TOOL WORKS INC.
    Inventors: Randall J. DuVal, Daniel C. Fosbinder, Nathan J. Jochman, Christopher J. Wierschke, John C. Leisner
