Tweco 1262-1037 Water Cooled Mig Nozzle 600 Amp WC26

Product Description

The TWECO 1262-1037 is a water-cooled MIG welding nozzle designed for the WC26 Series 600-amp water-cooled MIG gun platform. The nozzle housing is machined from tellurium copper alloy bar stock, providing consistent dimensional stability and efficient heat dissipation during high-amperage continuous welding operations. A spatter shield made from G7 silicone material is included with each unit. The part number is roll-stamped on the outside surface for easy field identification. Licensed welders and MIG welding technicians working in medium to heavy duty fabrication environments are the primary installers of this component.

This nozzle is suited for medium to heavy duty MIG welding applications running up to 600 amps. It threads directly onto the outer jacket assembly of water-cooled conductor tubes. The WC26 Series nozzle is compatible with Tweco Standard and Eliminator consumable systems, making it a direct-fit component for shops already running Tweco water-cooled gun setups. A Spatter Shield WC26-1 (Stock No. 1264-1009) is required for use and is sold separately.

Installation Notes

Installation should be performed by a qualified welding technician with the welding system fully powered down and water-cooling flow shut off before servicing. The nozzle threads onto the outer jacket assembly of the water-cooled conductor tube — ensure threads are clean and free of spatter buildup before installation. Do not overtighten, as this can damage the conductor tube jacket threads. Verify the spatter shield is seated correctly before returning the gun to service.
