KP4121-1-50R-B25 - Lincoln Magnum PRO Water-Cooled Robotic Nozzle .500 Recessed (25-Pack)

Reliable Robotic Welding Consumables

Maximize the efficiency of your automated welding cells with the Lincoln Electric KP4121-1-50R-B25 Magnum PRO Bottleneck Gas Nozzle. Sold in a convenient bulk pack of 25, these nozzles are engineered to meet the rigorous demands of high-volume manufacturing environments. When your production line relies on robotic precision, using genuine Lincoln Electric consumables ensures consistent performance, reduced downtime, and superior weld quality.

The Magnum PRO line is synonymous with durability. These specific nozzles feature a 0.500-inch (12.7 mm) bore diameter, a standard size for many medium-to-heavy duty applications. The bottleneck shape is particularly advantageous in robotic setups, as it tapers towards the outlet, allowing the torch to access tighter joints and complex angles that a standard cylindrical nozzle might obstruct. This design flexibility is crucial for automotive and general fabrication sectors where fixture clearance is often minimal.

Designed for water-cooled robotic torches, these nozzles are built to withstand the intense heat generated during prolonged welding cycles. Water cooling significantly extends the life of the consumable compared to air-cooled counterparts, preventing the nozzle from overheating and collecting excessive spatter. The recessed tip position further enhances durability by keeping the contact tip set back inside the nozzle. This configuration protects the tip from direct arc heat and reduces the likelihood of shorting against the workpiece, a common issue in tight-access welding.

Installation is quick and secure thanks to the thread-on design. Unlike slip-on nozzles that can loosen over time due to thermal cycling, the threaded connection ensures the nozzle remains concentric and firmly attached, maintaining proper gas shielding throughout the weld. Proper gas coverage is essential for preventing porosity and ensuring the structural integrity of the weldment. By choosing the KP4121-1-50R-B25, you are investing in a consumable that supports stable arc characteristics and clean weld beads.

This 25-pack configuration is ideal for inventory management in busy shops. Keeping a healthy stock of essential expendables minimizes the risk of line stoppages. Whether you are welding mild steel, stainless steel, or aluminum, the Magnum PRO platform delivers the reliability professional fabricators trust. Upgrade your robotic welding operations with nozzles designed for longevity and precision.
