Tweco, 12101120, Nozzle, 0.625" Bore, 2.224" Length, Recessed Tip, 21 Series

Tweco® Self Insulated Copper Nozzle with 0.625" bore size is designed for standard gas diffuser for use with up to 180 A Tweco® No. 1 MIG guns. 2.224" Nozzle with 3/4" OD is ideal for use in light to medium duty welding application up to 180 A. It features part number rolled stamped on the outer surface for easy identification. Nozzle with M11-1.5-6H threads size and recess contact tip relationship 0.125" - 0.156" is made of 122 DHP copper alloy. It has a 3-piece design that includes a nozzle housing, which is cut and formed from copper alloy tubing, a nozzle insert machined from a solid brass and a nozzle insulator constructed of silicone material. It has nozzle insert that allows machining of internal threads in order to match the gas diffuser. Nozzle offers electrical insulation required from the gas diffuser using the nozzle insulator. Nozzle is sold as 2 per pack.

Features

• 1/8' to 5/32" Tip recess
• Protruding Tips are generally used when welding open root pipe or any joint that requires the welder to get into a tight weld joint
• Nozzle Insert - machined from a solid brass allow and machining the internal threads to match the gas diffuser
• Nozzle threads onto the gas diffuser
• Easy identification - part no rolled stamped on the outside surface
• Thread-on
• 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
• Nozzle insulator - made from g7 silicone material, providing the electrical insulation needed from the gas diffuser
• 3-piece nozzle design, includes: Nozzle Housing - Cut and Formed from 122 DHP copper alloy tubing
• 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
• 3-piece design - does not require an additional 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)
