KP4120-1-75S-B25 - Lincoln KP4120-1-75S-B25 Magnum PRO Water-Cooled Nozzle 3/4" Stickout (25-Pack)

Lincoln Electric Magnum PRO Gas Nozzle - KP4120-1-75S-B25

The Lincoln Electric KP4120-1-75S-B25 is a premium gas nozzle designed specifically for the rigorous demands of automated welding environments. Part of the renowned Magnum PRO line, this nozzle is engineered to fit Magnum PRO Water-Cooled Robotic Torches, providing exceptional performance in high-amperage applications. This specific model features a large 0.75-inch (19.0 mm) bore diameter, making it ideal for applications requiring substantial shielding gas coverage to protect the weld pool from atmospheric contamination.

One of the standout features of this nozzle is its "Aluminum Stickout" configuration. In robotic aluminum welding, precise contact tip-to-work distance and nozzle geometry are critical for maintaining a stable spray transfer arc and preventing issues like burnback or soot accumulation. The KP4120-1-75S is designed to optimize these parameters, ensuring clean, high-quality welds on aluminum substrates. The thread-on connection mechanism is another vital attribute for robotic setups; unlike slip-on nozzles that can vibrate loose over time, the thread-on design ensures the nozzle remains concentric and securely attached, even during rapid torch movements and accelerations.

Supplied in a convenient bulk pack of 25, these nozzles are intended for high-volume industrial facilities where uptime is paramount. The robust construction of the Magnum PRO series ensures that these consumables last longer than standard nozzles, reducing the frequency of changeovers and minimizing downtime in your robotic cells. Whether you are fabricating automotive components, heavy machinery, or structural aluminum parts, the KP4120-1-75S-B25 delivers the reliability and consistency required for modern manufacturing.

Key Features:

• Water-Cooled Compatibility: Specifically built to withstand the thermal cycles of water-cooled robotic torches.
• Secure Fitment: Thread-on base prevents loosening and maintains gas flow alignment.
• Optimized Geometry: Aluminum Stickout design enhances performance for aluminum wire welding.
• Industrial Pack: Comes in a pack of 25 to support continuous production schedules.
