Grounding tab for a welding apparatus

A welding apparatus having a metal enclosure and a pair of plastic end panels affixed to the enclosure to contain therein the various components of the welding apparatus. A conductive grounding tab is affixed in a receptacle formed in each of the plastic panels and the grounding tab has a friction terminal for easy connection to a standard electrical connector of a grounding wire. The grounding tab has a pair of prongs having angled distal ends that forcefully engage the enclosure when the end panels are assembled to the enclosure to provide a good conductive path to ground from the metal enclosure through that ground wire and ultimately to a ground wire of a supply cable. A second grounding connection between the enclosure and the grounding tab is created by a screw that passes through the enclosure and is threaded into a threaded hole in the grounding tab.
