  • Publication number: 20230226632
    Abstract: Apparatus and methods are provided for a welding-type power system that includes an engine configured to drive an electric generator to provide a first power output. An energy storage device to provide a second power output. A controller is configured to receive one or more control signals to provide a total power output to at least one of a welding-type output or an auxiliary type output, determine proportional values for the first power output and the second power output that add up to the total power output based on a power demand signal that indicates a contribution of the first power output and the second power output, control the engine to adjust speed based on the first power output value, and control a connection from the energy storage device to provide the second power output to the welding-type output based on the second power output value.

  • Patent number: 11646598
    Abstract: 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.

  • Patent number: 11565339
    Abstract: Apparatus and methods are provided for a welding-type power system that includes an engine comprising a starter battery. An electric generator is turned by the engine. A power bus connects an output of the generator to a welding-type output. A sensor measures a power demand on the power bus. A controller is configured to control the engine to adjust speed in response to a measured power demand on the power bus, and to control a converter to connect the starter battery to output power to the power bus in response to the measured power demand.

  • Patent number: 10144083
    Abstract: 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.

  • Publication number: 20160308418
    Abstract: 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.
