The controller is configured to periodically compute a running current value during a welding operation. The controller is also configured to periodically compute a minimum current value based on a difference between the running current value and a preset offset value, wherein the preset offset value remains constant throughout the welding operation.Type: ApplicationFiled: December 17, 2009Publication date: September 9, 2010Applicant: Illinois Tool Works Inc.Inventors: Richard Martin Hutchison, James Lee Uecker

Publication number: 20100193489Abstract: An engine-driven welder/generator is controlled by an integrated controller that is coupled to both the engine and to the welder/generator. The controller receives input signals for operational parameters of the engine, and additional signals indicative of electrical output by the welder/generator. Operation of the engine and welder/generator may thus be coordinated. The controller may control speed, timing, fuel injection, and so forth of the engine, and output of the welder/generator, such as by control of input to a field coil.Type: ApplicationFiled: January 30, 2009Publication date: August 5, 2010Applicant: Illinios Tool Works Inc.Inventors: Richard Beeson, Daniel C. Fosbinder, Michael J. Trinkner
