Item Details

  • RADNOR™ Tweco® Style Standard Duty Copper Gas Diffuser is suitable to use with 15 H Series tips on up to 500 A Tweco® No. 5 MIG guns and is sold as 5 per pack.


  • Easy identification - part no rolled stamped on the outside surface
  • Contains a conduit set screw used to hold the conduit liner in place
  • Machined from tellurium copper alloy bar stock to ensure consistent dimensional stability
  • 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 500 Amp
  • Used with 45H-332, 45H-764 or 45H-18 Conduits
