Radnor® 2.224" 0.625" Bore 21 Series Nozzle

• Easy identification - part no rolled stamped on the outside surface
• 3-piece design - does not require an additional insulator
• Nozzle threads onto the gas diffuser
• 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 gas diffuser
• 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

Used in light to medium duty welding application up to 180 Amp
