Tweco 1264-1431 Robotic Mig Welding Nozzle Water-cooled

Product Description

The TWECO 1264-1431 is a water-cooled robotic MIG welding nozzle designed for use with robotic and fixed-automation MIG gun assemblies. Rated for medium to heavy-duty welding applications up to 400 amps, the nozzle features a bottle-shaped geometry and a straight inner bore measuring 1/2 inch in diameter. The housing is machined from tellurium copper alloy bar stock for consistent dimensional stability and efficient heat dissipation. A G7 silicone spatter shield is included with each unit. The nozzle threads onto the outer jacket assembly of water-cooled conductor tubes, making it a purpose-built component for automated weld cell installations.

This nozzle is engineered specifically for robotic and fixed-automation MIG welding setups operating in medium to heavy-duty environments. The straight ID bore at the front end of the nozzle is designed to work in conjunction with nozzle cleaning stations commonly integrated into robotic weld cells. The straight bore geometry allows thorough cleaning of sidewall surfaces, maintaining consistent shielding gas flow throughout the nozzle service cycle. It is well suited for production welding applications where duty cycle demands and weld cell automation require reliable, repeatable performance.

Key Features

• Rated for welding applications up to 400 amps, suitable for medium to heavy-duty use
• Water-cooled construction with nozzle housing machined from tellurium copper alloy bar for effective heat dissipation
• Bottle-shaped geometry with 1/2 inch straight inner bore diameter for consistent gas coverage
• Straight ID bore at the front end supports proper cleaning by nozzle cleaning stations in robotic weld cells
• G7 silicone spatter shield included with each nozzle for added spatter protection
• Part number roll-stamped on the outside surface for easy field identification
• Threads directly onto the outer jacket assembly of water-cooled conductor tubes

Compatibility

Designed for use with robotic and fixed-automation MIG guns, including the RWC26 water-cooled robotic MIG gun platform. Compatible with conductor tube assemblies using water-cooled outer jacket threading.

Installation Notes

Installation and replacement should be performed by a qualified welding technician or automation maintenance professional with the welding system fully powered down and water-cooling flow shut off before handling. Thread the nozzle onto the outer jacket assembly of the water-cooled conductor tube and confirm secure seating before resuming operation. Ensure the G7 silicone spatter shield is properly positioned prior to returning the gun to service. Follow all applicable welding equipment and robotic cell safety procedures during installation.
