Abstract: Methods and apparatus to power a crane on a work truck using an engine-powered service pack are disclosed. An example auxiliary power system for a vehicle includes an engine, a generator configured to convert mechanical energy from the engine to electrical energy, and power conversion circuitry configured to provide electrical power to a crane to enable the crane to lift at least a portion of a rated load, and configured to convert the electrical energy from the generator to output DC power.

Abstract: Apparatus and methods are provided for a welding-type power system that includes an engine configured to drive an electric generator to provide power to a power output, wherein a power signal is applied to the power output. A sensor monitors the power signal, and a controller determines a change in the power signal based on a feedback signal received from the sensor, and controls the engine to start or stop operation in response to the change in the power signal.

Abstract: Apparatus and methods are disclosed of a welding-type power source that includes a welding-type power source connected to a multi-mode power output circuit, a controller to receive an input from the welding-type power source and output a control signal to the multi-mode power output circuit. The controller is configured to identify whether a load at the multi-mode power output corresponds to a welding mode or a battery charging mode. The controller is also configured to control the multi-mode power output circuit to condition the power from the welding-type power source based on the identified one of the welding mode or the battery charging mode.

Abstract: A weld cable connector system that includes a first terminal and a terminal protection system. The first terminal includes a first lock feature. The first terminal is configured to couple with a welding component and to conduct a welding power. The terminal protection system includes a cap, a base coupled to the first terminal, and a tether coupled to the base and to the cap. The cap includes a first mating lock feature. The cap is configured to removably couple with the first terminal in a first locking position to separate the first terminal from an external environment. The first mating lock feature is configured to interface with the first lock feature.

Abstract: The present invention is directed to a power supply that maintains power supply to a plurality of electronic components of a welding system when an arc voltage falls below approximately 15 volts. The invention includes a power supply having a secondary supply circuit that improves the operable range of the power supply by maintaining power to components of a welding system when the arc voltage at a weld is greater than or equal to approximately 10 volts. As a result, the operable range of the power supply is no longer limited by the arc voltage. The invention includes a secondary power supply circuit having a power switch that when activated causes a buildup of energy in the transformer assembly whereupon deactivation of the power switch in the magnetic core is exhausted such that power supply is maintained. The power switch regulates the transformer assembly such that sufficient secondary power is provided if the input voltage to the transformer is as low as approximately 10 volts.
