Patent abstract
A torch for use in welding operations during which smoke and/or fumes are created has a nozzle and a handle connected to a conduit extending between the handle and the nozzle. A fume extraction duct extends from the nozzle and through the handle. An annular member surrounds the axial end of the nozzle and has a plurality of openings oriented such that fumes and ambient air are extracted in a direction substantially parallel to the longitudinal axis of the nozzle. A switch is provided to control fume extraction between a full flow rate and a partial flow rate.
