  • Patent number: 12059752
    Abstract: Engine-driven welding-type power supplies with portable welding units are disclosed. An example engine driven welder includes an engine, a generator configured to convert mechanical power from the engine to electric power, a chassis, the engine and the generator being mounted to the chassis, and a welding power supply configured to receive the electric power from the generator and convert the electric power to welding-type power, wherein the chassis is configured to physically hold the welding power supply, the welding power supply is physically separable from the chassis, and the welding power supply is connected to be able to receive the electric power when the welding power supply is separated from the chassis and when the welding power supply is connected to the chassis.

  • Patent number: 6796814
    Abstract: A power supply interface comprising electrical receptacles and intended for use outdoors or some other environment in which the receptacles can be exposed to water. Universal receptacle covers are used to cover exposed socket ends of the receptacles that have different geometric configurations. The universal receptacle cover comprises an adapter having an aperture with a geometric configuration that allows socket ends of different geometric configurations to project through the aperture. This avoids the need for receptacle covers with different configurations to accommodate the different socket ends.
