KP4120-1-50R - Lincoln Magnum PRO Robotic Nozzle .500 Recessed Water-Cooled

Optimize Your Robotic MIG Torch Performance

Achieve consistent, high-quality welds with the Lincoln Electric KP4120-1-50R Magnum PRO Gas Nozzle. Designed as a direct replacement for Magnum PRO Water-Cooled Robotic Torches, this nozzle is built to handle the demands of modern automated welding. Whether you are running mild steel, stainless, or aluminum, the condition and specification of your gas nozzle play a pivotal role in shielding gas coverage and arc stability. This nozzle delivers the reliability professional welders and maintenance technicians expect from the Lincoln Electric brand.

The KP4120-1-50R features a 1/2-inch (12.7 mm) bore, providing a focused column of shielding gas that is ideal for standard welding joints. Its recessed tip configuration is particularly beneficial for spray transfer modes or pulse welding where a longer wire stickout is necessary. By keeping the contact tip recessed, the nozzle helps shield the tip from the immediate harshness of the arc and reduces the likelihood of bridging spatter, which can disrupt gas flow and cause porosity. This design detail helps maintain a clean gas envelope around the weld pool, ensuring structural integrity and visual appeal.

One of the standout features of the Magnum PRO line is the thread-on design. In a robotic cell, vibration and rapid movement are constant. A thread-on nozzle guarantees that the component stays fixed in place, maintaining the programmed Tool Center Point (TCP). Additionally, the secure fit enhances the cooling efficiency of the water-cooled torch system. Efficient cooling prevents the nozzle from overheating, which keeps spatter from bonding tightly to the brass, making automated reaming cycles more effective and prolonging the life of the consumable.

For welding operations looking to maximize uptime and minimize consumable waste, the KP4120-1-50R offers a perfect balance of durability and precision. It integrates seamlessly with your existing Magnum PRO robotic setup, allowing for quick changeovers and consistent results shift after shift. Ensure your robotic cells are running at peak efficiency with genuine Lincoln Electric consumables.
