Radnor Self Insulated Copper Nozzle with 5/8" bore RADM2362 6400-2709 2 pack

Description

RADNOR® 3.219" Self Insulated Copper Nozzle with 5/8" bore size is designed to be used with 250 - 300 A Tweco® and RADNOR® Pro MIG guns.
A 3-piece nozzle design includes nozzle housing that is cut and made from 122 DHP copper alloys tubing. The nozzle insulator is made from G7 silicone material to render the electrical insulation required from the gas diffuser. A nozzle insert machined from a solid brass is included to allow machining of internal threads to match the gas diffuser. Nozzle with a recessed contact tip relationship finds application in medium to heavy duty welding up to 450 A.
Features

3-piece design - does not require an additional insulator
Nozzle housing - cut and formed from 122 dhp copper alloy tubing
Nozzle insulator - made from g7 silicone material, providing the electrical insulation needed from the gas diffuser
Nozzle Insert - machined from a solid brass allow and machining the internal threads to match the conductor tube OD threads
3-piece nozzle design, includes: Nozzle Housing - Cut and Formed from 122 DHP copper alloy tubing
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 heavy duty welding application up to 450 Amp
