  • Patent number: 9380717
    Abstract: A rectifier module comprises a conductive housing made of injection molded aluminum or aluminum alloy. Diodes are inserted into recesses formed in the housing. The housing is placed at an alternating input potential during operation, and transmits alternating current input power to the diode modules for conversion to direct current power. Multiple recesses may be provided for high and low side diodes, of which there may be one or many. Multiple such modules may be provided for converting multiple phases of input power to direct current power.

  • Publication number: 20160151851
    Abstract: An engine-driven welder generator is controlled based upon power draw for welding and other applications. Once a welding arc is initiated, the power draw is monitored. The engine speed, and therefore the power output of the generator, may be increased or maintained based upon the power draw. The power draw may include both welding power draw and auxiliary power draw. The engine speed is increased in increments. The initial engine speed and subsequent increments may depend upon particular welding processes or regimes.

  • Publication number: 20150322903
    Abstract: An engine-driven generator that controls fuel vapor flow is provided. The engine-driven generator includes an engine having an air intake, wherein the engine is configured to drive a generator. The engine-driven generator also includes a fuel tank coupled to the engine and configured to provide fuel to the engine. The engine-driven generator includes a valve coupled between the air intake of the engine and the fuel tank. The engine-driven generator also includes a control device configured to transition the valve between a first position and a second position. The first position allows fuel vapor to flow between the fuel tank and the air intake of the engine and the second position inhibits the fuel vapor from flowing between the fuel tank and the air intake of the engine.

  • Publication number: 20150108754
    Abstract: A power converter for an engine generator includes an insulative support that receives and supports circuit components for converting incoming AC power to desired power, such as power suitable for a welding application. One or more rectifier modules are provided that are received and supported by the support. Three such modules may be provided for receiving three phase power from a generator. DC power from the rectifier module is applied to DC bus plates. The plates may be coupled to capacitors. A power conversion circuit, such as a buck converter, is coupled to the DC bus plates to convert the DC power to output power.

  • Patent number: 9000328
    Abstract: A system, in one embodiment, may include an engine, a compressor coupled to the engine, and an oil fill assembly coupled to the compressor. The oil fill assembly relocates an oil fill location from a bottom region of the compressor to a top region of the compressor. A system, in other embodiments, may include a compressor retrofit kit. The kit may include a first tube configured to couple with a drain or an existing oil fill disposed in a base region of a compressor. The kit also may include a second tube coupled to the first tube, wherein the second tube is configured to couple with a vent in the compressor. The kit may include a relocated oil fill section coupled to the first tube, the second tube, or a combination thereof. A system having a compressor retrofit kit attached to the case of the compressor is also provided.

  • Publication number: 20130239927
    Abstract: A governor system is provided that includes a governor having an actuator, and a coupler link configured to couple at a first end to the actuator and at a second end to a throttle of an engine being controlled. One or more mechanical characteristics of the coupler link, the throttle, an actuator arm of the actuator, or some combination thereof, are specific to the engine and configured such that each position of the actuator causes a given output of the engine independent of particular characteristics of the engine.
