    摘要： A securement member for securing a contact tip to a welding torch assembly is provided. A channel extends axially therethrough and has an internal shoulder that extends into this channel. This internal shoulder abuts against a shoulder on the contact tip, capturing the contact tip between the shoulder and a seating surface on the diffuser and securing the contact tip in the torch assembly. The contact tip is securely seated without threading engagement, facilitating quick release and installation. The exemplary securement member couples to the diffuser such that the egress of fluid from the diffuser is blocked when used for gasless welding. This blocking allows a user to leave the diffuser secured to the welding torch when a gasless electrode is in use.

    摘要： A welding system includes a welding torch assembly including a body, a first feed roll, a second feed roll, and a lever. The first and second feed rolls are both configured to rotate with respect to the body, and the first and second feed rolls are disposed opposite from one another about a welding wire feed region. The lever is configured to pivot at a first end of the lever about a lever joint of the body, and the second feed roll is movable between a first position and a second position in response to movement of a second end of the lever. The second feed roll is adjacent to the first feed roll in the first position, the second feed roll is not adjacent to the first feed roll in the second position, and the lever is configured to maintain the feed roll in the second position.

    摘要： An end assembly for use with a welding device having a contact tip, a diffusor, an insert, and an gooseneck, and the contact tip has a convex end that contacts a concave end of the insert, and the insert has an opposite end in contact with the gooseneck. The contact tip is threaded into the diffusor at one end of the diffusor, and the gooseneck is threaded into the diffusor at the opposite end of the diffusor, and the insert is disposed within the diffusor and between the contact tip and the gooseneck, such that a conductive path exists between the gooseneck, the insert, and the contact tip. The contact tip, insert and gooseneck are constructed of a conductive material which are securely held together in contact by the diffuser constructed of a dissimilar material.

    摘要： A diffuser insert is provided for use with a welding diffuser and contact tip assembly comprising a diffuser with an interior chamber configured to receive a wire conduit that supplies electrode wire and a shielding gas used during a welding operation and a contact tip coupled to the diffuser and configured to receive electrode wire. The diffuser insert comprises a diffuser insert body configured to be disposed within the interior chamber of the diffuser, and further comprises an insert bore extending therethrough configured to receive electrode wire. An outer periphery of the diffuser insert has at least one surface feature configured to manipulate a flow of said shielding gas from within said interior chamber of the diffuser and out of exit passages to thereby direct said flow of shielding gas about a molten welding puddle formed during a welding operation.

    摘要： A consumable component for use in an arc welding apparatus is provided that functions as both a contact tip and a diffuser. The consumable component includes a body having an internal cavity extending from a proximal end portion to a distal end portion. At least one slot extends through an outer wall of the body, between the proximal end portion and the distal end portion and into the internal cavity. An exit orifice extends through the distal end portion of the body, defining a radiused inlet in one form of the present disclosure.
