Item Details

  • Tweco® 15H Series Standard Duty Copper Gas Diffuser with 500 A Tweco® can be use for No.5 MIG gun series as well as eliminator front-end consumables. Gas diffuser has magnificent electrical properties making it ideal for use in medium to heavy duty standard welding application up to 500 A. It comes with 45H-332, 45H-764 and 45H-18 conduits. It features part number rolled stamped on the external surface and overall length for easy identification. Gas diffuser is made from tellurium copper alloy bar stock offers consistent dimensional stability. Gas diffuser features a conduit set screw that can accommodate the 3/32" conduit liner in place. It has a proper threaded conductor tube to use with MIG guns. Gas diffuser 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
