KP4121-1-62F-B25 - Lincoln Magnum PRO Robotic Nozzle, 5/8 Flush, Water-Cooled (25-Pack)

Precision and Durability for Magnum PRO Torches

Upgrade your robotic welding setup with the Lincoln Electric KP4121-1-62F-B25 Magnum PRO Bottleneck Gas Nozzle. Designed for professional fabricators and automation engineers who demand precision, this nozzle fits Magnum PRO Water-Cooled Robotic Torches. The water-cooled compatibility is crucial for high-duty cycle applications where air-cooled consumables would overheat and fail prematurely. By effectively managing heat, this nozzle maintains its structural integrity and resists spatter adhesion longer than standard counterparts.

The KP4121-1-62F-B25 features a 5/8-inch (15.9 mm) orifice, a standard size for many industrial MIG applications, providing excellent gas coverage for solid and flux-cored wires. Its bottleneck shape is a key advantage, reducing the nozzle's profile to allow the robot to maneuver into difficult joints without collision. The flush tip relationship is ideal for short-circuit and spray transfer modes where you need the contact tip close to the work for electrical efficiency but protected enough to maintain laminar gas flow.

Installation is secure and straightforward thanks to the coarse thread-on design. Unlike slip-on nozzles that can become loose or misaligned due to thermal expansion, the threaded connection ensures the nozzle remains concentric with the contact tip. This concentricity is vital for robotic repeatability, ensuring the Tool Center Point (TCP) remains constant. Sold in packs of 25, these nozzles are an essential component for maintaining the efficiency and quality of your automated welding operations.
