KP4120-1-75F-B25 - Lincoln Magnum PRO 3/4-Inch Flush Gas Nozzle for Robotic Torches (25-Pack)

Reliable Performance for Robotic Cells

When your production line relies on robotic automation, every second of downtime counts. The Lincoln Electric KP4120-1-75F-B25 Magnum PRO Gas Nozzle is built to keep your water-cooled robotic torches running smoothly shift after shift. Designed for the heavy-duty Magnum PRO series, these nozzles are tough enough to handle the heat of high-amperage welding while delivering the precision needed for automated welds. This 25-pack bulk option is perfect for busy shops that need to keep inventory stocked without constant reordering, ensuring your maintenance team can swap out consumables quickly and get the robot back to work.

The 0.75-inch (3/4") bore is a standout feature for applications requiring robust gas coverage. Whether you are running aluminum wire or heavy steel sections, the wide opening ensures that your shielding gas fully envelops the weld pool, reducing the risk of porosity and rework. The "Flush" tip design places the nozzle edge level with the contact tip, which is often the sweet spot for many welding procedures, offering a balance between gas coverage and access to tight joints. Because it is a thread-on nozzle, you don't have to worry about it rattling loose as the robot arm swings rapidly between welds; it stays locked in place, keeping your gas flow centered and your arc consistent.

Operators and maintenance technicians appreciate the quality of Lincoln's Magnum PRO consumables. They resist spatter buildup better than generic alternatives, meaning the nozzle cleaning station (reamer) doesn't have to work as hard, and the nozzles last longer before needing the scrap bin. Whether you are setting up a new cell or optimizing an existing process, switching to these high-performance nozzles can help smooth out your operations. The aluminum-specific design considerations in this model help ensure that even difficult materials run cleaner and more consistently.
