KP4120-1-38R - Lincoln Electric Magnum PRO Robotic Nozzle .375 Recessed Water-Cooled

Optimize Your Robotic Cell with the KP4120-1-38R Magnum PRO Nozzle

Maximize the efficiency of your automated welding operations with the Lincoln Electric KP4120-1-38R Magnum PRO Gas Nozzle. Designed explicitly for Magnum PRO Water-Cooled Robotic Torches, this consumable is built to withstand the intense heat and continuous operation typical of robotic welding cells. When your production line depends on uptime, using genuine Lincoln Electric consumables ensures that your equipment operates at peak performance levels, delivering consistent weld quality part after part.

The KP4120-1-38R features a 3/8-inch (9.5 mm) orifice, offering a tight and controlled gas coverage pattern. This size is excellent for accessing tighter joints or when precision gas shielding is required to prevent porosity. The nozzle is defined by its recessed tip stick-out. This configuration places the contact tip slightly back inside the nozzle, providing a natural shield against spatter bridging and protecting the tip from accidental contact with the workpiece or fixture. It allows for a versatile electrical stick-out (ESO), which can be crucial for fine-tuning arc characteristics in MIG/MAG processes.

One of the standout features of this nozzle is its thread-on design. In a robotic environment, stability is key. The threaded connection guarantees that the nozzle remains perfectly concentric and securely attached, even during rapid arm movements and accelerations. This secure fit also promotes efficient cooling by establishing a solid thermal path to the water-cooled torch neck, preventing the nozzle from overheating and melting. Keeping the nozzle cool also helps prevent spatter from sticking, making the automatic reaming or cleaning cycles more effective.

Whether you are welding mild steel, stainless, or aluminum in an automated setting, the Magnum PRO platform offers durability you can trust. This nozzle is designed to integrate seamlessly with your existing Magnum PRO expendables, making changeovers quick and hassle-free. Ensure your robotic welding system delivers the high-quality results you expect by choosing the correct nozzle for the job.
