Tweco 1210-1341 Mig Nozzle 180A 0.5 in Bore Air Cooled

Product Description

The TWECO 1210-1341 is a slip-on MIG welding nozzle designed for light to medium duty applications rated up to 180 amperes. Part of the Weldskill 21 Series, it features a 3-piece construction with a nozzle housing cut and formed from 122 DHP copper alloy tubing, a solid brass nozzle insert with machined internal threads, and a G7 silicone nozzle insulator. The silicone insulator provides electrical isolation from the gas diffuser without requiring a separate add-on insulator. With a 0.5 inch bore and tip recess ranging from 0.125 inches to 0.156 inches, it delivers consistent shielding gas coverage across a range of wire diameters.

This nozzle is suited for air-cooled MIG welding setups used in fabrication, maintenance, and general shop welding. The slip-on design allows for fast nozzle changes in production environments. The part number is roll-stamped on the outside surface for quick identification in multi-gun shops or when managing inventory across multiple welding stations. It threads onto the gas diffuser, making fitment straightforward for welders familiar with 21 Series torch configurations.

Key Features

• Rated up to 180 amperes for light to medium duty MIG welding
• 3-piece nozzle design: 122 DHP copper alloy housing, solid brass insert, G7 silicone insulator
• Self-insulating construction eliminates the need for a separate insulator
• Slip-on installation threads directly onto the gas diffuser
• Tip recess of 0.125 inches to 0.156 inches for proper shielding gas delivery
• Part number roll-stamped on exterior for easy identification

Compatibility

Designed as an OEM-style replacement nozzle for TWECO 21 Series air-cooled MIG welding torches using a slip-on nozzle configuration.

Installation Notes

Installation is performed by welding technicians or experienced welders. Always power down the welder and ensure the machine is de-energized before replacing the nozzle. Thread the nozzle onto the gas diffuser by hand until seated; do not overtighten. Inspect the nozzle insulator and gas diffuser for spatter buildup or damage at each nozzle change.
