Welding stream nozzle useful in manual- and automatic burner, preferably in metal active gas-welding, comprises metallic base body, wire feed channel, and pressure part with pressure surface for exerting pressure force on welding wire

摘要

Welding stream nozzle comprises a metallic base body (01), a wire feed channel extending in the base body, and a pressure part (09) with a pressure surface for exerting a pressure force on a welding wire (17), which is led to the conveyor in the wire feed channel. The wire feed channel extends in a longitudinal direction of the base body. The pressure surface extends along a portion of the wire feed channel. A spring (15) is provided for elastically connecting the base body and the pressure part.
