Tweco 1220-1341 Mig Welding Nozzle 0.5 Inch Bore

Product Description

The TWECO 1220-1341 is a MIG welding nozzle from the Weldskill 22 Series, designed for use with standard gas diffusers on MIG welding guns rated up to 250 amps. The nozzle body is cut and formed from copper alloy tubing, offering reliable thermal performance and durability under continuous welding conditions. The bore measures 0.5 inches in diameter, and the overall nozzle length is 2.1 inches. The part number is rolled and stamped on the outer surface for fast field identification. This nozzle is sold in a pack of 2 and is installed by welding technicians performing light to medium duty MIG welding work.

The 1220-1341 is suited for light to medium duty MIG welding applications up to 250 amps. It slides over the standard nozzle insulator and features an adjustable recess-to-protruding contact tip relationship, allowing the technician to set the preferred contact tip and nozzle position for the weld joint and process at hand. It is a practical replacement nozzle for professional welders working in fabrication, maintenance, and repair environments where consistent shielding gas coverage is critical to weld quality.
