KP4120-1-38S-B25 - Lincoln KP4120-1-38S-B25 Magnum PRO Robotic Nozzle 3/8 Stick-Out (25-Pk)

Reliable Shielding for Magnum PRO Robotic Systems

Maximize the efficiency of your robotic welding cells with the Lincoln Electric KP4120-1-38S-B25 Magnum PRO Gas Nozzle. This 25-pack of nozzles is designed to keep your automation running smoothly with minimal interruption. The KP4120-1-38S features a 3/8-inch (9.5 mm) bore and a "Stick Out" tip relationship, which is particularly useful when the robot needs to weld in corners or complex geometries where a flush or recessed tip might cause the nozzle to interfere with the workpiece. By allowing the contact tip to extend appropriately, this nozzle ensures the arc is established exactly where it is needed while still delivering a laminar flow of shielding gas to protect the molten puddle.

Built for the Magnum PRO Water-Cooled Robotic Torch series, these nozzles are constructed to endure extreme thermal stress. Water-cooled systems are typically employed in high-amperage welding where air-cooled torches would overheat; consequently, the consumables at the front end must be equally resilient. The thread-on mounting style is a favorite among maintenance technicians and operators because it is quick to replace but stays firmly locked in place during operation. Unlike slip-on nozzles that might shift or vibrate loose over time, the threaded connection guarantees that the nozzle remains perfectly aligned with the contact tip, reducing the risk of arcing against the nozzle wall and extending the life of the consumable.

Choosing genuine Lincoln Electric parts for your Magnum PRO system ensures compatibility and performance. The copper alloy construction offers excellent thermal conductivity, helping to pull heat away from the front end and reduce spatter adhesion. When spatter does accumulate, the high-quality finish makes cleaning easier, whether done manually or via an automated reaming station. With this bulk pack of 25, you can ensure your tool crib is stocked and your robots keep burning wire, delivering the high-quality welds your customers expect.
