END ASSEMBLY FOR WELDING DEVICE

An end assembly for use with a welding device having a contact tip, a diffusor body, and a gooseneck. The contact tip has a convex end surface that contacts and mates with a concave end of the diffuser body. The diffuser body forms a blind bore forming central web and a series of passageways. A long...

description An end assembly for use with a welding device having a contact tip, a diffusor body, and a gooseneck. The contact tip has a convex end surface that contacts and mates with a concave end of the diffuser body. The diffuser body forms a blind bore forming central web and a series of passageways. A longitudinal 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 longitudinal 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 first and second passageways of the contact tip to provide shielding gas to the weld site and cool the contact tip during welding operations.
