Abstract: An electric arc welder power supply housing assembly is described in which it is possible to clean internal component parts is achieved by positioning cooling components on a rail system. The rail system may include at least one telescoping track assembly. When the telescoping track assembly is engaged, the housing assembly is in an open position, thus providing access for the maintenance of internal components therein without having to disassemble unnecessary components or parts of the welding power supply.

Abstract: A welding system component includes a circuit board for the welding system component. An interface has a main riser portion with a fastener passageway formed therethrough.

Abstract: A tube clip is mounted to a channel-section track and is used to secure a pipe. The channel-section track includes a pair of upper engagement surfaces having inwardly turned flanges spaced apart by a slot. The tube clip includes an integrally molded, one-piece elongated cylindrical body that extends along a first axis and defines a center bore for receiving the pipe therethrough. A base is fixedly secured to the cylindrical body and includes a pair of support surfaces spaced apart along the first axis. Each support surface includes a fin for engaging one of the upper engagement surfaces of the channel-section track to bias the tube clip therefrom. A pair of flexible legs extends from the base portion. The legs are spaced apart along the first axis and each leg is adapted to selectively lockingly engage one of the flanges when the tube clip is mounted to the channel-section track.
