KP4120-1-38F - Lincoln Magnum PRO Robotic Water-Cooled Flush Nozzle 3/8 Inch

Precision Consumables for Automated Welding

In the realm of robotic welding, consistency is the currency of productivity. The Lincoln Electric KP4120-1-38F Magnum PRO Gas Nozzle is engineered to deliver that essential reliability for high-volume manufacturing environments. Designed specifically for use with Magnum PRO Water-Cooled Robotic Torches, this nozzle is a critical component for maintaining arc stability and shielding gas integrity during extended welding cycles.

Optimized for Water-Cooled Systems

Water-cooled torches are the standard for high-amperage applications where heat dissipation is paramount. This nozzle is constructed to interface seamlessly with Lincoln's water-cooled front-end parts, ensuring that thermal energy is efficiently managed. By keeping the nozzle cooler, spatter adherence is significantly reduced, and the lifespan of the consumable is extended. This thermal management is crucial for preventing the premature degradation of the nozzle bore, which can lead to turbulent gas flow and porosity in the weld.

Flush Geometry and Bore Precision

The KP4120-1-38F features a flush tip relationship, meaning the contact tip sits flush with the end of the nozzle. This configuration is widely favored for its versatility, offering a balance between gas coverage and accessibility. It allows for a standard electrode stick-out while ensuring the shielding gas envelope fully protects the weld pool. With a 0.375-inch (9.5 mm) bore, this nozzle provides a focused gas column, ideal for tighter joints or applications requiring precise gas delivery without excessive waste.

Secure Thread-On Design

Vibration and movement are constant in robotic arms. The thread-on connection of the Magnum PRO series ensures that the nozzle remains securely seated throughout the operation, maintaining concentricity with the contact tip. This mechanical stability prevents the nozzle from loosening, which could otherwise disrupt the gas shield or cause arcing against the fixture. For fabricators demanding uptime and quality, this Lincoln Electric consumable is the professional choice.
