摘要： The present disclosure is directed to systems and methods for pretreating a wire that is used in a welding operation to reduce the amount of hydrogen introduced into a weld. Using embodiments of the systems and methods disclosed herein, one passes a wire through a pre-treatment chamber in which a wire is treated to release hydrogen and/or other contaminants, and provides a gas flow through the pre-treatment chamber so that the contaminants that are released from the wire are taken up by the gas. The gas exiting the pre-treatment chamber may be isolated from the shielding gas utilized during a welding operation. For instance, the pretreatment gas may be directed away from the distal end of the welding torch, thereby preventing released contaminants from being transported into a weld.

摘要： A gas metal arc welding system for a robotic arm includes a j-arm, a power block, and a bolt. The j-arm has a first end and a second end each having a through hole. The power block has a first opening defining a first passageway along a longitudinal axis and a second opening defining a second passageway substantially along an axis perpendicular to the longitudinal axis. The bolt has a threaded portion configured to extend through the first opening of the j-arm and into the second passageway of the power block, wherein the bolt retains the j-arm to the power block. The threaded portion of the bolt comprises an internal passageway that extends through a longitudinal axis of the bolt, wherein the internal passageway of the bolt and the first and second passageways of the power block are in fluid communication with each other.

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.
