12401315 - Tweco REL24CT50 Robotic Water-Cooled Nozzle 1/2" Bore (Pack of 2)

Technical Overview of the Tweco REL24CT50 Robotic Nozzle

The Tweco 1240-1315 (Model REL24CT50) is a specialized MIG welding nozzle engineered specifically for the rigorous demands of robotic automation. Unlike standard air-cooled consumables, this nozzle is designed for water-cooled robotic MIG guns, allowing it to withstand the high amperage and continuous duty cycles characteristic of automated manufacturing environments. The nozzle belongs to the Tweco 24 Series family of consumables, ensuring compatibility with a wide range of existing robotic torch setups that utilize this standard platform.

Technically, the REL24CT50 features a 0.500-inch (1/2") bore diameter, which provides a balanced shielding gas envelope suitable for medium-to-heavy fabrication tasks. The "CT" in the part number designates "Coarse Thread," a critical design feature for automation. Coarse threads are less susceptible to seizing from thermal expansion and spatter ingress compared to fine threads, and they allow for faster removal and replacement during maintenance intervals—crucial for minimizing cell downtime. The nozzle is constructed from high-grade copper alloy, optimized for thermal conductivity to efficiently transfer heat away from the contact tip and diffuser area into the water-cooled torch body.

This product is supplied in a pack of two, recognizing the consumable nature of nozzles in high-volume production. By maintaining tight manufacturing tolerances, Tweco ensures that the Tool Center Point (TCP) remains consistent when nozzles are swapped, reducing the need for frequent robot reprogramming or touch-ups. The REL24CT50 is an essential component for maintaining process stability in water-cooled robotic welding cells.
