Tweco® Heavy-duty Nozzle with 3/4" size is designed for standard gas diffuser and ensures the quality of the welds as well as the life of the gun. It is used in heavy-duty welding applications for up to 450 A. It features part number rolled stamped on the outer surface for easy identification. Nozzle with a flush contact tip relationship 0.062" which is used where longer electrical stick-out is used sometimes which brings the tip closer is made of 122 DHP copper alloy. It has a 3-piece design that includes a nozzle housing that is cut and formed from copper alloy tubing, a nozzle insert machined from a solid brass and nozzle insulator constructed of silicone material. It has nozzle insert that allows the nozzle to 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.
Features
Easy identification - part no rolled stamped on the outside surface
3-piece design - does not require an additional insulator
Nozzle insulator - made from g7 silicone material, providing the electrical insulation needed from the gas diffuser
Nozzle insert - machined from a solid brass allows 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
