Item Details

  • RADNOR™ 2.1" Adjustable Copper Nozzle with 5/8" bore size is designed to be used with up to 250 A Tweco® No. 2 and RADNOR™ Pro MIG guns. Nozzle housing is cut and made from 122 DHP copper alloys tubing. Nozzle featuring flush, protruding and recessed contact tip relationship finds application in light to medium duty welding up to 250 A.


  • Easy identification - part no rolled stamped on the outside surface
  • Nozzle is adjustable to obtain the contact tip and nozzle relationship wanted
  • Nozzle housing - cut and formed from 122 dhp copper alloy tubing
  • Nozzle slides over the standard nozzle insulator
  • 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 light to medium duty welding application up to 250 Amp
