  • Patent number: 7767934
    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.

  • Publication number: 20060278626
    Abstract: A torch assembly and welding system are disclosed. The torch assembly includes a handle section having a wire feeder attached thereto. A conduit having a barrel positioned thereabout is positioned between the handle section and a nozzle. The conduit communicates a shielding gas and a consumable weld wire from the handle section to the nozzle. A space is maintained between the barrel and the conduit and provides a thermal barrier therebetween.
