Abstract: Systems and methods for a welding-type power supply to provide both a welding output voltage and a battery charging output voltage. The power supply includes a first contactor associated with a first circuit to provide the welding output voltage, and a second contactor associated with a second circuit to provide the battery charging output voltage. An auxiliary switch is operatively coupled to the second contactor, to prevent the first circuit from closing when the second contactor is closed to prevent transmission of the welding output voltage to the second circuit.

Abstract: A hydraulic load ramping system, in certain aspects, may utilize load sensing feedback from an engine, thereby reducing the possibility of overloading the engine as well as smoothing the transition between hydraulic load levels. In particular, by ramping between hydraulic load levels, unwanted movement of hydraulically-driven equipment may be minimized. In addition, by efficiently monitoring the load sensing feedback and ramping between hydraulic load levels, the hydraulic output may be maximized.

Abstract: The present embodiments provide a system having a motor, a compressor having a compression device configured to increase a pressure of a gas, a clutch configured to selectively transfer torque from the motor to the compressor to drive the compression device, and a controller configured to disengage the clutch if the pressure of the gas in the compressor meets or exceeds a first threshold pressure.

Abstract: A load control system, in certain aspects, may be configured to decrease the amount of noise pollution of a prime mover (e.g., engine) of a service pack in that it may not require the prime mover to operate at higher discrete operating speeds to deliver small amounts of air from the air compressor. The load control system may also only increase the speed of the prime mover to a minimum discrete speed required, keeping noise at a minimum. The load control system may also maximize fuel efficiency by not operating the prime mover at the highest discrete speed at all times. More specifically, the lower operating speeds may lead to less fuel consumption.

Abstract: A power management system, in certain aspects, may utilize direct load sensing feedback from the prime mover (e.g., engine), thereby reducing the possibility of overloading the prime mover. The use of direct load sense feedback from the prime mover can then be used with additional feedback, such as prime mover RPM feedback and individual output load sensing feedback, to directly control the output loads and set the primary power sources rpm set-point to better manage the power available and reduce the possibility of overloading the primary power source.
