KP4120-1-75R - Lincoln Magnum PRO Robotic Nozzle, 3/4" Bore, Recessed Tip, Thread-On

Heavy-Duty Performance for Water-Cooled Torches

When you are running a robotic welding line, the last thing you want is a nozzle failure stopping production. The Lincoln Electric KP4120-1-75R Magnum PRO Gas Nozzle is built to handle the heat. Designed for water-cooled Magnum PRO robotic torches, this nozzle keeps your operation running smooth and cool. It features a secure thread-on design that locks tight onto the diffuser, ensuring it won't vibrate loose during fast robot slewing and providing excellent heat transfer to keep the front end from overheating.

This particular nozzle comes with a large 3/4-inch (19.0 mm) opening, which is perfect for laying down big beads and ensuring you have plenty of gas coverage. The "Recessed" designation means your contact tip sits back inside the nozzle. This is a huge advantage when you are welding at high amperages or using spray transfer, as it helps shield the contact tip from the direct heat of the arc and reduces the chance of the tip shorting out against the work. It is especially useful for aluminum applications where burnback and spatter can be a nightmare for standard flush tips.

Durability is key with the Magnum PRO series. These nozzles are tough enough to withstand the daily abuse of an industrial environment. Whether you are welding thick aluminum plate or heavy steel structures, the KP4120-1-75R helps maintain a stable arc and clean welds by delivering consistent gas flow. The recessed design also acts as a bit of a spatter guard for your contact tip, meaning fewer tip changes and more arc-on time. Upgrade your robotic torch consumables to genuine Lincoln Electric parts and see the difference in longevity and weld quality.
