Item Details

  • Tweco® Heavy Duty Brass Nozzle with a 0.625" bore size fits standard gas diffuser and is designed to use for 600 A Tweco® MIG guns. 3.29" Nozzle has a 1.187" OD and is used in heavy-duty welding applications for up to 600 A. It features part number rolled stamped on the outer surface for easy identification. Nozzle with a recess contact tip relationship 0.125 - 0.156" that is used where longer electrical stick-out is needed or when the nozzle touches the work place is made of 230 brass alloy. It has a 3-piece design that includes a nozzle housing that is cut and formed from red brass alloy tubing, a nozzle insert machined from a solid brass and nozzle insulator constructed of silicone material. It has nozzle insert that allows it slide over a metal spring of the gas diffuser. Nozzle offers electrical insulation required from the gas diffuser using the nozzle insulator and is sold as 2 per pack.


  • Easy identification - part no rolled stamped on the outside surface
  • Two-piece nozzle design - nozzle housing threads onto the nozzle insulator
  • Nozzle housing and nozzle insulator sold separately
  • Nozzle housing - Cut and formed from red brass alloy 230
  • 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 heavy duty welding application up to 600 Amp
