Patent number: 11027356Abstract: 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: GrantFiled: December 4, 2018Date of Patent: June 8, 2021Assignee: Illinois Tool Works Inc.Inventors: Randall J.
