Tweco RWC2662 Water-Cooled Robotic MIG Nozzle 5/8" Bore (2-Pack)

Keep Your Robot Running Cool

When your robotic welding cell is running full tilt, the last thing you need is a nozzle failure stopping production. The Tweco RWC2662 (Part #1264-1431) is built to handle the heat. Designed specifically for water-cooled robotic torches, this nozzle is the workhorse you need for high-volume, high-amperage welding jobs. Unlike standard nozzles that might overheat and collect excessive spatter, the water-cooled design of the RWC2662 helps keep the front-end consumables at a manageable temperature, making spatter easier to clean and extending the life of the nozzle itself.

This nozzle features a standard 5/8-inch bore, which is the go-to size for most general purpose and heavy-fabrication robotic welding. It provides excellent gas coverage whether you are welding mild steel, stainless, or aluminum. The 5/8" opening is wide enough to prevent bridging from spatter buildup but focused enough to keep your shielding gas right where it needs to be—over the puddle. Because it is a genuine Tweco part, you can trust the threads to screw on smoothly and seat firmly every time, ensuring your gas diffuser and contact tip stay protected.

Sold in a convenient pack of two, this kit ensures you always have a backup handy. In a robotic environment, downtime is money. Having a fresh RWC2662 ready to go means you can swap out a worn or clogged nozzle during a scheduled pause and get the line moving again instantly. Whether you are running a single cell or managing a fleet of robots, sticking with high-quality, water-cooled consumables like the Tweco RWC2662 is a smart move for consistent weld quality and reduced maintenance headaches.
