摘要:
A method and apparatus provides welding-type power and preferably includes a removable battery or other energy storage device, a converter connected to the battery, and a controller. The controller may have a CV and/or a CSC and/or an AC weld control module, and/or an ac auxiliary control module. The converter is a boost converter, a buck converter, a cuk converter, a forward converter, an inverter, a bridge converter, and/or a resonant converter. The controller may include a battery charging control module, and may have one or more charging schedules, and/or data for stored charge, thermal information, expected life of the battery, maximum amp-hour charge for the battery, maximum charging current and/or feedback. The battery charging schedules may include at least 3 phases, such as a phase of increasing voltage and a phase of decreasing current, a substantially constant power phase. The controller can wirelessly provide data to a display or pda. A generator may provide power to the battery, charger, and/or the weld. It can include a vehicle and use its dc power system.

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.

A method and apparatus for welding with an engine driven inverter power supply includes generating an ac output with an engine and generator. The output is rectified and inverted to provide an ac inverter output. The engine is controlled using feedback indicative of a welding output operating parameter. The feedback may also be taken from the inverter or generator, and the generator may be controlled instead of or in addition to the engine. Engine parameters that may be controlled include engine speed, selecting between an idle speed and a run speed, a throttle position, a fuel pump, an injection timer, a fuel to air ratio, fuel consumption and ignition timing. Another aspect of the invention is having the feedback be responsive to one or more of the welding current, welding voltage, welding power, or functions thereof. The feedback may be responsive to the current, voltage, power, ripple and functions thereof. An aux power output is derived directly from the generator and feedback from the aux load is used to determine if the engine should be idling or running at high speed.

摘要:
A system and method are provided for controlling an internal combustion engine driving a generator/welder or a stand-alone generator. The engine and/or the generator is controlled based upon settings for welding. Controlling the engine may include altering the engine speed based upon a detected demand on the generator and/or operating parameters of a welder.

A service pack for a work vehicle provides service systems, which may include an electrical generator, a hydraulic pump and an air compressor. The service pack is driven by an engine separate from that of the vehicle. Integration of the support systems for the vehicle engine and service engine may be provided. The service pack allows the vehicle engine to be shut down when at a service location, with the service pack engine alone providing the necessary electrical, hydraulic and compressed air services for maintenance and other service work.
