Abstract (en)
[origin: WO2022103385A1] An end assembly for use with a welding device having a contact tip, a diffusor body, and a gooseneck. The contact tip has an end surface that contacts and mates with an end of the diffuser body. The diffuser body forms a bore forming central web and a series of passageways. A passageway segment is formed in the contact tip parallel with the central longitudinal electrode bore of the contact tip. A second passageway segment joins the first passageway segment. When the contact tip is affixed to the diffuser body, a chamber is formed at the base of the contact tip communicating with the diffuser body passageways. Shielding gas that flows into the diffuser body passes through the web passageways into the chamber and through the passageways of the contact tip to provide shielding gas to the weld site and cool the contact tip during welding operations.
