Mounting receptable for welding apparatus component

A welding apparatus comprises an enclosure and a molded end panel affixed to the enclosure to form an enclosed area. The molded end panel has an internal surface facing inwardly toward the enclosed area and an opening, receptacle formed in the internal surface surrounding the opening and comprising sides extending outwardly from the internal surface forming a polygonal configuration, and at least one flexible finger. A welding apparatus comprises an enclosure (12) and a molded end panel affixed to the enclosure to form an enclosed area within the enclosure for locating components used in the welding apparatus. The molded end panel has an internal surface facing inwardly toward the enclosed area and an opening, receptacle formed in the internal surface surrounding the opening and comprising sides extending outwardly from the internal surface forming a polygonal configuration, and at least one flexible finger extending outwardly from the internal surface and having a distal end formed into a barb. The receptacle receives a component having a body shaped in the same polygonal configuration of the receptacle. The finger is adapted to fit over the component to retain the component within the receptacle. An independent claim is also included for a method of assembling a component to the surface of a molded plastic end panel, comprising providing a molded plastic panel; providing a component to be affixed to the end panel having a polygonal body; and inserting the component into the receptacle, causing the barb at the distal end of the finger to hook over the component to retain the component within the receptacle.
