Tweco 1244-1110 Water Cooled Mig Nozzle 1/2 Inch 400A

Product Description

The TWECO 1244-1110 is a water-cooled MIG welding nozzle designed for medium to heavy-duty welding applications rated up to 400 amps. Machined from tellurium copper alloy bar stock, the nozzle delivers consistent dimensional stability and efficient heat dissipation under sustained high-amperage operation. The 1/2 inch bore suits standard gas diffuser configurations. Each unit ships with a G7 silicone spatter shield. The manufacturer part number is rolled and stamped directly onto the external surface for quick identification in the field. Licensed welders and MIG welding technicians are the primary installers of this component.

This nozzle is suited for medium to heavy-duty MIG welding operations where water-cooled conductor tubes are in use. It threads onto the outer jacket assembly of water-cooled conductor tubes, making it appropriate for continuous or high-duty-cycle welding environments such as fabrication shops, structural steel work, and industrial manufacturing lines. Compatible with Tweco and Tweco Supra MIG guns as noted by the manufacturer.

Key Features

Compatibility

Compatible with Tweco and Tweco Supra MIG guns. Designed to thread onto the outer jacket assembly of water-cooled conductor tubes in medium to heavy-duty MIG welding setups.

Installation Notes

Installation should be performed by a qualified welding technician. Before servicing or replacing the nozzle, shut down the welding power source and allow the water-cooled conductor tube assembly to depressurize and cool. Thread the nozzle onto the outer jacket assembly by hand first to avoid cross-threading, then snug with appropriate tooling. Verify spatter shield is properly seated before resuming operation.
