KP4121-1-50R - Lincoln Magnum PRO Water-Cooled Robotic Nozzle .500 Recessed

High-Performance Robotic Welding Consumables

The Lincoln Electric KP4121-1-50R is a premium gas nozzle engineered specifically for the rigorous demands of automated manufacturing. Part of the Magnum PRO series, this nozzle is designed to integrate seamlessly with Magnum PRO Water-Cooled Robotic Torches. In high-volume production environments, equipment reliability is paramount. This nozzle features a robust construction capable of withstanding the intense heat cycles associated with continuous robotic welding, ensuring consistent performance and reducing downtime for consumable changes.

The nozzle features a 0.500-inch (12.7 mm) bore diameter, which provides a balanced shielding gas flow ideal for standard wire diameters used in automation. The "bottleneck" geometry is a critical design element for robotic applications, as it tapers towards the outlet to minimize the nozzle's profile. This allows the robotic arm to access tighter joints and complex angles without mechanical interference, expanding the operational envelope of the welding cell. The thread-on connection mechanism ensures a concentric fit and maximizes thermal conductivity, pulling heat away from the front end to prolong the life of the consumable.

Furthermore, the recessed contact tip relationship offers protection for the contact tip against spatter and radiant heat, while allowing for a specific electrical stickout (ESO) often required in automated programming. By utilizing genuine Lincoln Electric Magnum PRO expendables, facility managers can ensure their robotic systems operate at peak efficiency with consumables designed to match the precise specifications of the torch assembly.
