Patent number: 11646598Abstract: A welding-type power system that includes an engine configured to drive an electric generator to provide a first power output. In addition to the electric generator, the system includes an energy storage system to provide a second power output. The system includes energy storage devices and charging devices that are used to charge the energy storage devices. A controller is configured to control the charging devices to provide charging power output to the energy storage devices based on the parameters related to the charge level of the energy storage devices. The controller, using data received from sensors and charge measurement devices, determines the respective charge level for each energy storage device; compares the respective charge levels to one or more threshold charge levels; and controls the charging devices to provide a charging power output to the energy storage devices with a charge level that is below a threshold charge level.Type: GrantFiled: October 18, 2019Date of Patent: May 9, 2023Assignee: Illinois Tool Works Inc.Inventor: David Edwin Radtke

Patent number: 10144083Abstract: An engine driven welder includes a generator configured to provide an electrical output, an engine coupled to the generator, an air compression system coupled to the engine, a first welding system coupled to the generator, and a second welding system. The engine is configured to drive the generator, and the air compression system is configured to provide a pneumatic output. The first welding system is configured to provide a first weld output, and the second welding system is configured to provide a second weld output. The second weld output is independent of the first weld output in an independent mode, and the second weld output is combined with the first weld output as a combined weld output in a parallel mode.Type: GrantFiled: March 14, 2013Date of Patent: December 4, 2018Assignee: ILLINOIS TOOL WORKS INC.Inventors: David Edwin Radtke, Alan Fredrick Smith, George Harold Baus, Joseph Carl Gitter

Publication number: 20160308418Abstract: A one-piece generator housing locates and secures the generator stator assembly, rotor bearings, and brush holder, and provides for attachment of the housing assembly to the engine interface. The disclosed one-piece housing completely encloses the stator and rotor assembly of the generator. An embodiment of the one-piece generator housing is applied to welding machine applications that use an in-line engine. With this type of engine, the power take-off (PTO) is normally the engine flywheel, and the variety of engine interfaces to which to mount the generator become more diverse. In an embodiment, the rotor has a flange with integral cooling fan blades that bolts to the flywheel. A shorter adapter is used in order to access the fasteners that attach the rotor shaft to the flywheel. The housing attaches to the adapter using cast-in bosses and bolts.Type: ApplicationFiled: April 12, 2016Publication date: October 20, 2016Inventors: Paul William Garvey, David Edwin Radtke
