Tweco 1264-1441 Robotic Mig Nozzle 600A 5/8 Inch Bore

Product Description

The TWECO 1264-1441 is a water-cooled robotic MIG welding nozzle rated for medium to heavy-duty applications up to 600 amps. The nozzle housing is machined from tellurium copper alloy bar stock, which provides consistent dimensional stability and efficient heat dissipation at high amperages. A straight inside-diameter bore at the front end allows thorough cleaning of the sidewall surfaces, maintaining reliable shielding gas flow during continuous operation. The bottle-shaped geometry and water-cooled design make this nozzle well-suited to high-cycle robotic weld cells where thermal management and repeatability are critical. A G7 silicone spatter shield is included with each nozzle for added protection of surrounding components.

This nozzle is designed for use with robotic and fixed automation MIG guns, specifically those equipped with water-cooled conductor tubes. It is intended for medium to heavy-duty welding environments where arc-on time is high and amperage demands approach or reach 600 A. The straight ID bore makes it an ideal candidate for use alongside automated nozzle cleaning stations commonly integrated into robotic weld cells, reducing downtime and maintaining consistent gas coverage between cleaning cycles. The part number is roll-stamped on the exterior surface for quick visual identification during tooling changes.

Key Features

• Rated up to 600 amps for medium to heavy-duty MIG welding
• Water-cooled design with tip flush configuration for high-duty-cycle robotic applications
• Nozzle housing machined from tellurium copper alloy bar for heat dissipation and dimensional consistency
• Straight ID bore enables proper sidewall cleaning and consistent shielding gas flow

• Part number roll-stamped on exterior for fast identification during equipment changeovers

Compatibility

Designed for use with robotic and fixed automation MIG guns using water-cooled conductor tube outer jacket assemblies, consistent with the RWC26 platform. Verify conductor tube outer jacket thread specification before installation.

Installation Notes

Installation should be performed by a qualified welding technician or automation integrator. De-energize the welding power source and shut off the water-cooling supply before removing or installing the nozzle. The nozzle threads onto the outer jacket assembly of the water-cooled conductor tube — do not overtighten, as this can damage the thread interface on the conductor tube. Confirm shielding gas flow rate and water-cooling circuit integrity before returning the system to service.
