KP4120-1-38R-B25 - Lincoln Magnum PRO Robotic Nozzle 3/8 Recessed Water-Cooled (25-Pack)

Lincoln Electric KP4120-1-38R-B25 Magnum PRO Gas Nozzle (25-Pack)

The Lincoln Electric KP4120-1-38R-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, ensuring seamless integration into your existing automation cells. This specific model features a 0.375-inch (9.5 mm) bore diameter, making it ideal for applications requiring tight access or precise gas shielding on smaller weld pools. The nozzle is constructed to withstand the intense heat generated during high-amperage, continuous welding cycles typical of robotic operations.

One of the defining features of the KP4120-1-38R is its recessed tip relationship. By positioning the contact tip slightly back inside the nozzle, the design helps protect the tip from shorting against the workpiece and provides a more stable shielding gas column, which is critical for maintaining weld quality in drafty industrial environments. The thread-on connection mechanism is a significant upgrade over slip-on designs for robotics; it ensures the nozzle remains concentric and securely attached even during the rapid acceleration and deceleration of robotic arms, preventing accidental dislodgement and ensuring consistent Tool Center Point (TCP) repeatability.

This product is supplied in a bulk package of 25 units, catering to high-volume manufacturers who require a steady supply of consumables to minimize downtime. The water-cooled architecture of the nozzle aids in rapid heat dissipation, significantly extending the service life of the consumable compared to standard air-cooled counterparts. Whether you are welding mild steel, stainless, or aluminum in an automated setting, the Lincoln KP4120-1-38R-B25 delivers the reliability and performance necessary to keep your production lines moving efficiently.
