    • Easy identification - part no rolled stamped on the outside surface
    • Designed to be used with course thread nozzle assemblies
    • Machined from 360 brass alloy bar stock to ensure consistent dimensional stability
    • Gas diffuser provides the od course threads so that the nozzle assembly can attach to the conductor tube
    • Gas diffuser has a silicon O-ring to seal against the nozzle assembly
    • Replacement O-ring Part No EL52-1 (Stock No 1560-1108)
    • Recessed Tips are generally used for higher heat applications where longer electrical stick-out is required, or in cases where the nozzle may touch the work piece (tack, spot, and stitch)
    • Flush Tips are generally used where a shorter electrical stick-out is used sometimes resulting in shorter/tighter arc lengths, this brings the tip closer to the work piece
    • Protruding Tips are generally used when welding open root pipe or any joint that requires the welder to get into a tight weld joint
    • However the down side to this is the chance of arcing the tip to the work piece, which could damage front end parts resulting in downtime needed to replace


    • Used in medium to heavy duty welding application up to 600 Amp
