Tweco® Copper Nozzle with 0.625" bore size is designed for standard gas diffuser for use with up to 250 A Tweco® no.2 MIG guns. 2.1" Nozzle with 3/4" OD is ideal for use in light to medium duty welding application up to 250 A. It features part number rolled stamped on the outer surface for easy identification. Nozzle will easily slide over the standard nozzle insulator. It can be adjusted to achieve the desired contact tip and nozzle relationship. Nozzle with adjustable recess to protruding contact tip relationship is made of 122 DHP copper alloy and is best suited for higher heat applications requiring longer electrical stick-out or in cases where the nozzle touches the work piece. It has nozzle housing, which is cut and formed from copper alloy tubing. Nozzle is sold as 2 per pack.
Features
Easy identification - part no rolled stamped on the outside surface
Nozzle is adjustable to obtain the contact tip and nozzle relationship wanted
Nozzle housing - cut and formed from 122 dhp copper alloy tubing
Nozzle slides over the standard nozzle insulator
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
Applications
Used in light to medium duty welding application up to 250 Amp
