ABSTRACT:
An electrically and thermally conductive adapter for connecting a weld electrode to a tip holder portion of a welding device. The adapter has a first, threaded end, for removable engagement with a like-threaded receiving cavity in the tip holder. The threads may be of parallel configuration to minimize damage to the receiving cavity. The adapter has a second, preferably tapered end, for receiving a removable weld electrode. A passageway is preferably provided through the adapter for transporting cooling fluid to the electrode. An o-ring may be retained on the adapter and designed to engage with a groove in the receiving cavity in order to prevent leakage of cooling fluid from around the threads. The adapter is economical to manufacture and may be quickly and easily removed or installed to the tip holder. The adapter reduces damage to the tip holder commonly caused by the repeated changing of electrodes.
