Item Details

  • RADNOR™ 2.224" Copper Nozzle with 5/8" bore size is designed to be used with up to 180 A Tweco®, Tweco® No. 1 MIG guns. Self-insulated nozzle with a recessed tip relationship is ideal for higher heat applications and is sold as 2 per pack.


  • Easy identification - part no rolled stamped on the outside surface
  • 3-piece design - does not require an additional insulator
  • Nozzle threads onto the gas diffuser
  • Nozzle insulator - made from g7 silicone material, providing the electrical insulation needed from the gas diffuser
  • Nozzle Insert - machined from a solid brass allow and machining the internal threads to match the gas diffuser
  • 3-piece nozzle design, includes: Nozzle Housing - Cut and Formed from 122 DHP copper alloy tubing
  • 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
  • Thread-on


  • Used in light to medium duty welding application up to 180 Amp
