Tweco 1220-1336 Tapered Nozzle 3/8 in Bore 250A Mig

Product Description

The TWECO 1220-1336 is a Weldskill 22 Series tapered MIG welding nozzle rated for light to medium duty applications up to 250 amps. The nozzle features a 3/8 inch (0.375 inch) bore and measures 3.015 inches in length with a 3/4 inch outer diameter. The housing is cut and formed from 122 DHP copper alloy tubing, delivering solid thermal conductivity and corrosion resistance. The part number is rolled and stamped on the outer surface for fast identification in the field. This nozzle is sold as a 2-pack and is installed by MIG welding technicians performing production or maintenance welding tasks.

The 1220-1336 is designed for use with standard gas diffusers in light to medium duty MIG welding setups. It slides over the standard nozzle insulator (Part No. 32, Stock No. 1320-1100) and is adjustable to set the desired contact tip and nozzle relationship. The tip-flush copper alloy construction protects weld quality and extends gun service life. Typical applications include fabrication, maintenance, and repair welding where amperage demands stay at or below 250 amps.
