Tweco® Coarse Threaded Brass Nozzle with 1/2" bore size is perfect for standard gas diffuser. 3.183" Nozzle with 0.875" OD making it ideal for use in light to medium duty welding application up to 250 A. It features part number rolled stamped on the external surface for easy identification. Nozzle with recess contact tip relationship 0.125 - 0.156" is made from copper alloy. It has a 3-piece design without an additional insulator includes a nozzle housing, which is cut and formed from 122 DHP copper alloys tubing, a nozzle insert machined from a solid brass and nozzle insulator constructed from silicone material. It features threads on the standard EL gas diffuser. It has nozzle insert that crimped in place to let the nozzle to slide over a metal spring that is a part of the gas diffuser. Nozzle offers electrical insulation required from the gas diffuser using the nozzle insulator. Nozzle is sold as 2 per pack.

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
Thread-on
Applications
Used in light to medium duty welding application up to 250 Amp
