KP4121-1-62S-B25 - Lincoln Electric Magnum PRO Robotic Nozzle, 5/8" Bottleneck, Stickout, Water-Cooled (25 Pack)

Keep Your Robots Running with Magnum PRO Nozzles

In the world of robotic welding, downtime is the enemy. The Lincoln Electric KP4121-1-62S-B25 Magnum PRO Gas Nozzle is built to keep your automation cells productive and your weld quality consistent. Designed specifically for Magnum PRO Water-Cooled Robotic Torches, these nozzles are tough enough to handle the heat of continuous, high-amperage welding without premature failure. This pack contains 25 nozzles, ensuring your maintenance team has the stock they need to perform quick changeovers and keep the line moving.

Precision Design for Tough Joints
The bottleneck shape of this nozzle is a game-changer for reaching into corners and welding tight angles that standard cylindrical nozzles can't touch. With a 5/8-inch (0.625") bore, it provides excellent gas coverage to prevent porosity, while the "Stick Out" design allows the contact tip to extend slightly past the nozzle edge. This configuration is often preferred for better arc control and preventing the nozzle from dipping into the weld pool in tight fillets.

Secure and Durable
Robotic arms move fast, and the last thing you need is a nozzle falling off mid-cycle. The KP4121-1-62S features a secure thread-on design that locks the nozzle firmly in place, resisting vibration and impact. This threaded connection also helps transfer heat away from the nozzle and into the water-cooled torch body, extending the life of the consumable. Whether you are welding mild steel, stainless, or aluminum, these genuine Lincoln Electric parts deliver the reliability your operation demands.
