Tweco 1220-1342 Tapered Mig Welding Nozzle 250A

Product Description

The TWECO 1220-1342 is a tapered MIG welding nozzle from the Weldskill 22 Series, designed for use with standard gas diffusers on light to medium duty MIG welding guns rated up to 250 amps. The nozzle measures 3.015 inches in length with a 3/4-inch outer diameter and is constructed from 122 DHP copper alloy tubing, offering solid thermal conductivity and corrosion resistance. The part number is roll-stamped on the outer surface for fast identification in the field. Sold in a pack of 2, this nozzle is a practical stock item for shops running consistent MIG operations.

This nozzle is suited for light to medium duty welding applications up to 250 amps. It slides over the standard nozzle insulator and is adjustable to set the desired contact tip-to-nozzle relationship. Typical install scenarios include production welding benches, fabrication shops, and field MIG gun maintenance where consistent shielding gas coverage and repeatable tip positioning are required. The copper alloy housing promotes even heat dissipation during sustained welding cycles.

Installation Notes

Installation is performed by welding technicians or maintenance personnel servicing MIG welding guns. Always power down and disconnect the welding machine before replacing the nozzle. Slide the nozzle over the nozzle insulator and adjust to the desired contact tip relationship before securing. Inspect the copper housing for spatter buildup regularly and replace when internal bore shows signs of deformation or excessive spatter accumulation.
