KP4120-1-75F - Lincoln Magnum PRO Robotic Nozzle, 3/4" Bore, Flush, Thread-On

Reliable Nozzles for Your Robotic Cell

When your production line depends on robotic welding precision, you can't afford to compromise on the front-end consumables. The Lincoln Electric KP4120-1-75F Magnum PRO Gas Nozzle is built to keep your robots running and your welds clean. This isn't just a standard cup; it's a heavy-duty, thread-on nozzle designed specifically for Lincoln's Magnum PRO Water-Cooled Robotic Torches. If you are running high-heat cycles or welding aluminum, this 3/4-inch (19.0 mm) bore nozzle delivers the massive gas coverage you need to keep porosity at bay and ensure smooth, clean beads every time.

The "Flush" design of this nozzle means your contact tip sits right at the edge of the nozzle opening. This is a favorite setup for many operators because it offers a great balance—you get excellent gas coverage without the nozzle getting in the way of the puddle, and it helps prevent the tip from shorting out against the work as easily as a recessed tip might in tight corners. Because it threads on, you don't have to worry about it vibrating loose or falling off mid-cycle. That tight threaded connection also helps pull heat away from the tip, keeping everything cooler and lasting longer, even when you are pushing the duty cycle to the limit.

Spatter build-up is the enemy of robotic efficiency, causing reamers to work overtime and potentially throwing off your TCP. The KP4120-1-75F is engineered to resist spatter adhesion, making your reaming cycles more effective and less frequent. Whether you are fabricating heavy structural aluminum or precision automotive parts, swapping to genuine Lincoln Electric Magnum PRO consumables ensures your equipment performs exactly as the manufacturer intended. Keep your arc stable, your gas flow laminar, and your production targets on track with this professional-grade nozzle.
