Abstract
A torch and a welder having a torch constructed to pull a consumable weld wire thereto are disclosed. The torch includes a wire feeder assembly having a first feed roll and a second feed roll. Operation of the feed rolls pulls a consumable weld wire to the torch. A lever selectively separates the first and the second feed rolls and is securable to allow a hands-free separation of the feed rolls.
