KP3160-1-50R - Lincoln Magnum PRO 350A Thread-On Nozzle, 1/2" Bore, 1/8" Recess

Genuine Lincoln Electric KP3160-1-50R Nozzle

The Lincoln Electric KP3160-1-50R is a premium thread-on gas nozzle designed specifically for the Magnum PRO 350A series of MIG welding guns. This consumable is a critical component in the Magnum PRO expendables system, engineered to deliver consistent shielding gas coverage and extended service life in industrial welding environments. The nozzle features a 1/2-inch (12.7 mm) inner diameter bore, which provides a balanced gas flow suitable for a wide range of wire diameters, specifically from .035 inches up to 5/64 inches. The bottleneck shape of this nozzle is particularly advantageous for operators working in restricted spaces, as the tapered front end allows for better visibility of the weld puddle and easier access to tight joints compared to standard straight nozzles.

One of the defining features of the KP3160-1-50R is its 1/8-inch (3.2 mm) recessed tip relationship. This recess positions the contact tip slightly back inside the nozzle, offering protection against spatter accumulation on the tip itself and reducing the risk of electrical shorts against the workpiece. This configuration is often preferred for higher amperage applications where radiant heat is significant, or when using spray transfer modes. The nozzle is constructed with a robust nickel plating. This plating is not merely cosmetic; it serves a functional purpose by resisting the adhesion of weld spatter. By preventing spatter from bonding tightly to the nozzle surface, the nickel finish makes cleaning easier and extends the operational life of the consumable, reducing downtime for maintenance.

The "Thread-On" mechanism of this nozzle utilizes coarse threads that are designed to prevent seizing. In high-heat welding environments, thermal expansion and contraction can often cause fine-threaded components to lock together, making replacement difficult. Lincoln's coarse thread design ensures that the nozzle can be easily unscrewed even after repeated heating cycles. Furthermore, the threaded connection guarantees precise concentricity between the contact tip and the nozzle bore, ensuring that the shielding gas is centered around the wire for optimal weld quality. This nozzle is sold individually and is an essential stock item for facilities utilizing Magnum PRO 350A equipment.

Compatibility is key with the KP3160-1-50R. It is designed to mate perfectly with Magnum PRO 350A gas diffusers. It is not compatible with slip-on style diffusers. By using genuine Lincoln Electric consumables, users ensure that their equipment operates at the rated duty cycle and performance levels intended by the manufacturer.
