Zusammenfassung: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.
