Tweco 1262-1033 Water Cooled Mig Nozzle 600 Amp WC26

Product Description

The TWECO 1262-1033 is a water cooled MIG welding nozzle from the WC26 Series, designed for use with 600 amp Tweco Standard water cooled MIG guns. The nozzle housing is machined from tellurium copper alloy bar stock, providing consistent dimensional stability and efficient heat dissipation under sustained high-amperage operation. With a 3/4 inch bore and a length of 3.27 inches, this nozzle threads directly onto the outer jacket assembly of water cooled conductor tubes. It ships with a spatter shield made from G7 silicone material. Licensed welding professionals and industrial MIG operators performing medium to heavy duty fabrication work are the primary installers.

The 1262-1033 is suited for medium to heavy duty MIG welding applications requiring continuous or high-duty-cycle output up to 600 amps. It is compatible with Tweco Standard or Eliminator consumables, making it a direct fit in existing WC26 Series torch configurations. A Spatter Shield WC26-1 (Stock No. 1264-1009) is available separately and is designed to be used in conjunction with this nozzle. Applications include structural fabrication, heavy plate welding, and industrial manufacturing environments where sustained high-amperage output demands reliable thermal management.

Key Features

• Machined from tellurium copper alloy bar for dimensional stability and efficient heat dissipation
• 3/4 inch bore diameter supports high-flow shielding gas coverage at elevated amperages
• Rated for welding applications up to 600 amps, suitable for medium to heavy duty work
• Includes G7 silicone spatter shield for each nozzle unit
• Part number roll-stamped on the outer surface for quick field identification
• Threads onto the outer jacket assembly of water cooled conductor tubes

Compatibility

Compatible with Tweco Standard or Eliminator consumables used on 600 amp Tweco Standard water cooled MIG guns in the WC26 Series. Designed for use with Spatter Shield WC26-1 (Stock No. 1264-1009), sold separately.

Installation Notes

Installation should be performed by a qualified welding technician or maintenance professional. Before servicing or replacing the nozzle, shut down the welding power source and allow the water cooled torch to depressurize and cool completely. Thread the nozzle onto the outer jacket assembly by hand to avoid cross-threading, then snug with appropriate tooling. Verify shielding gas flow and cooling water connections before resuming welding operations.
