KP4121-1-50S-B25 - Lincoln Magnum PRO Robotic Nozzle .500 Stick-Out Bottleneck (25 Pack)

Maximize Uptime with Magnum PRO Reliability

For professional fabricators and automation technicians, the Lincoln Electric KP4121-1-50S-B25 Magnum PRO Bottleneck Gas Nozzle offers the consistency needed to keep robotic welding cells running smoothly. When your production line depends on the repeatability of every arc start and the quality of every bead, using genuine Lincoln Electric consumables is a smart investment. This nozzle is specifically built for Magnum PRO Water-Cooled Robotic Torches, designed to handle the high amperage and high duty cycles that would melt lesser components. The water-cooled compatibility ensures that the nozzle stays cooler for longer, resisting the buildup of spatter and reducing the frequency of cleaning cycles required by the reamer station.

Access Tight Spots with Ease

The bottleneck shape of this nozzle is a game-changer for welding parts with difficult geometry. If you are welding inside chassis frames, around brackets, or in deep grooves, the slim profile of the bottleneck allows the torch to get right where it needs to be without snagging on clamps or the part itself. The 0.500-inch (12.7 mm) opening provides excellent gas coverage for standard wire sizes, ensuring porosity-free welds. Additionally, the "Stick Out" design is perfect for applications where you need the contact tip to be closer to the work or where you need better visibility of the arc location during programming and touch-sensing operations.

Secure and Durable

Nothing is worse than a nozzle vibrating loose during a shift. The KP4121-1-50S features a secure thread-on mechanism that locks the nozzle in place, ensuring perfect alignment with the contact tip. This concentricity is vital for maintaining a stable arc and even gas flow. The high-quality copper alloy construction withstands intense heat, and the smooth surface finish helps repel spatter. Sold in a convenient 25-pack, this product ensures your tool crib is stocked and your robots stay operational, minimizing changeover time and maximizing throughput.
