Abstract: A hinge arrangement for a welder enclosure includes a door panel having at least one hinge at one end that is engagable in a slot of a base to allow the door panel to move between a maximum closed position to a maximum open position. The hinge and slot arrangement of the door panel and base allow the door panel to open and close through a rotation point from a maximum open position to a maximum closed position, and also allows complete removal of the door panel at certain positions between the maximum open position and the maximum closed position.

Abstract: A housing of a welding-type device includes a bezel which encloses a plurality of electrical receptacles and a plurality of terminal posts of the welding-type device. The bezel has a first and a second opening corresponding to each terminal post. The plurality of first openings has hinged covers attached to the bezel over the openings. The plurality of second openings is uninterrupted through the bezel and constructed such that the bezel provides strain relief to a welding cable which passes therethrough. The covers are formed such that they allow passage of an electrical cable through the first opening with the cover in a closed position.

Abstract: A fuel tank assembly for supplying fuel to an engine that drives an electric generator. The fuel tank assembly is incorporated in a power generation system comprising an internal combustion engine; an electric generator driven by the engine; and a support frame for supporting the engine, the fuel tank assembly and the generator. The fuel tank is supported at an elevation above the engine and is not mounted to the engine. One embodiment of the fuel tank assembly comprises a rotomolded plastic fuel tank having a lattice of stiffening ribs projecting from its bottom, a heat shield disposed between the engine and the fuel tank and in contact with the stiffening ribs, and a plurality of fasteners that fasten the heat shield to the fuel tank. The heat shield/fuel tank assembly is mounted to the support frame.

Abstract: An apparatus having an engine-driven generator wherein the fuel tank, engine, air cleaner, muffler and battery are arranged in accordance with a space-saving design, and the size of the fuel tank is maximized. This is accomplished in part by placing the fuel tank and muffler at different elevations, so that the muffler does not limit the footprint of the fuel tank. In particular, the fuel tank is supported at an elevation above the engine, while the muffler is attached to and disposed on one side of the engine. The muffler occupies a space located between the battery and the air cleaner. The muffler outlet is disposed at an elevation lower than the elevation of the engine exhaust port.

Abstract: A rotor assembly having a rotor shaft, a rotor winding mounted to the rotor shaft, an electrically insulative body mounted to the rotor shaft, an electrically conductive collector ring supported by the electrically insulative body, a wire lead electrically connecting the winding to the collector ring, and a fastener engaged with a boss of the collector ring. The wire lead has a portion that is wrapped around a first portion of the fastener and pressed into contact with the boss of the collector ring by a second portion of the fastener. A collector ring assembly having two or more collector rings is formed by insert molding.

Abstract: An engine driven welder has a fuel tank with a filler tube that extends upwardly from a reservoir in the machine base. The filler tube upper end and a cap thereon are below the machine top cover. The machine top cover has a cutout into which is installed a grommet that closes the cutout and that fully protects the filler tube upper end and the cap. The grommet has a hole that seals over a top portion of the filler tube such that any spilled fuel does not leak inside the machine. The filler tube has an expansion space that prevents splashback and spillover during fueling. An angled tail pipe directs engine exhaust away from the welding machine in any desired direction.

Abstract: The generator of an engine-driven welding machine is comprised of front and rear housings that attach directly to each other. The generator stator maybe secured solely to one or the other housing with preloaded screws. Alternately, one or more preload elements may be interposed between the stator and one of the front or rear generator housings. Thermal stresses are thereby avoided between the stator and the generator housings, despite the housings being made of aluminum and the stator being made of steel. The rear generator housing has an end wall that is mountable to different selected internal combustion engines by means of teardrop shaped clearance holes and machineable bosses. Slots for cooling air in the rear generator housing have sides with tangential components. Air leaves a fan in the generator with tangential components that are matched by the rear generator housing slots. The fan incorporates both fan blades and a baffle having a close clearance with an annular wall of the rear generator housing.
