Tweco 1264-1442 Robotic Mig Nozzle 600A 3/4 Inch Water-cooled

Product Description

The TWECO 1264-1442 is a water-cooled robotic MIG welding nozzle rated for medium to heavy-duty applications up to 600 amps. Designed for robotic and fixed-automation MIG guns, it features a bottle-shaped geometry and a straight-bore inner diameter measuring 3/4 inch. The nozzle housing is machined from tellurium copper alloy bar for consistent dimensional stability and efficient heat dissipation. Each unit ships with a G7 silicone spatter shield. The part number is roll-stamped on the exterior for quick identification on the floor. Welding technicians and robotic cell integrators working in high-amperage automated environments install this nozzle as part of a water-cooled conductor tube assembly.

This nozzle is built for robotic weld cells running medium to heavy production loads. The straight inner-diameter bore at the front end allows a nozzle cleaning station to properly scrub the sidewalls, maintaining consistent shielding gas flow across weld cycles. It threads directly onto the outer jacket assembly of water-cooled conductor tubes and is well-suited for cells where automated nozzle cleaning stations are integrated into the cycle. Applications include continuous or high-duty-cycle MIG welding at current levels up to 600 A where water cooling is required to manage heat.

Key Features

• Rated up to 600 amps for medium to heavy-duty MIG welding
• Water-cooled design with tip-flush geometry for high-duty-cycle robotic cells
• Bottle-shaped geometry with straight inner-diameter bore for effective nozzle-station cleaning
• Housing machined from tellurium copper alloy bar for heat dissipation and dimensional stability
• G7 silicone spatter shield included with each nozzle
• Part number roll-stamped on exterior surface for fast identification
• Threads onto the outer jacket assembly of water-cooled conductor tubes

Compatibility

Designed for use with robotic and fixed-automation MIG guns, specifically the RWC26 water-cooled conductor tube assembly. Intended for nozzle cleaning stations integrated into robotic weld cells.

Installation Notes

Installation is performed by qualified welding technicians or robotic cell maintenance personnel. Shut down the welding power source and relieve water-cooling system pressure before removing or installing the nozzle. Thread the nozzle onto the outer jacket assembly by hand to avoid cross-threading the copper housing. Verify shielding gas flow and water-cooling circuit integrity before returning the cell to production.
