Item Details

  • RADNOR™ Slip-On Copper Nozzle with 5/8" bore size is designed to be used with 300 - 450 A Tweco® Spray Master® and RADNOR™ Master MIG guns. A 3-piece nozzle design includes nozzle housing that is cut and made from 122 DHP copper alloys tubing. The nozzle insulator is made from G7 silicone material to render the electrical insulation required from the gas diffuser. A nozzle insert machined from a solid brass is included to allow machining of internal threads to match the gas diffuser. Heavy-duty nozzle with a recessed contact tip relationship finds application in medium to heavy duty welding up to 450 A 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 housing - cut and formed from 122 dhp copper alloy tubing
  • 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 is crimped in place to allow the nozzle to slide over a metal spring which is part of the gas diffuser
  • 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 450 Amp
