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

High-Performance Consumables for Robotic Automation

The Lincoln Electric KP4120-1-38S-B25 Magnum PRO Gas Nozzle is a premium consumable engineered specifically for the rigorous demands of automated welding environments. Designed for use with Magnum PRO Water-Cooled Robotic Torches, this nozzle features a 0.375-inch (9.5 mm) bore diameter, providing focused shielding gas coverage essential for high-quality weld deposits. The "Stick Out" configuration of this nozzle is tailored to allow the contact tip to protrude slightly or sit in a specific relationship to the nozzle face, which is often critical in robotic programming for accessing tight joints or maintaining specific electrical stick-out (ESO) parameters without compromising gas shielding.

In high-production manufacturing, downtime is the enemy. Lincoln Electric's Magnum PRO line addresses this by utilizing robust materials capable of withstanding the intense heat generated by high-amperage, water-cooled applications. The thread-on design of the KP4120-1-38S ensures a secure mechanical connection to the diffuser, maintaining perfect concentricity. This prevents the nozzle from loosening during the rapid movements and accelerations typical of robotic arms, ensuring consistent tool center point (TCP) repeatability. The water-cooled compatibility means these nozzles are built to handle 100% duty cycles often found in automotive and heavy fabrication sectors.

This product is supplied in a bulk package of 25 units (B25), making it an ideal choice for facility managers and procurement specialists looking to streamline inventory for welding cells. By maintaining a healthy stock of these essential consumables, operations can ensure seamless changeovers and maintain high equipment availability. Whether welding mild steel, stainless, or aluminum in an automated cell, the reliability of the gas nozzle plays a pivotal role in preventing porosity and weld defects. Trust Lincoln Electric's engineering to deliver consistent performance shift after shift.
