KP2742-2-50S - Lincoln Electric Magnum PRO 350A Slip-On MIG Nozzle, 1/2" Bore, 1/8" Stickout

Optimize Your Magnum PRO Gun with the KP2742-2-50S

The Lincoln Electric KP2742-2-50S is a standard slip-on gas nozzle designed to deliver superior performance for Magnum PRO 350A MIG guns. As a vital part of the Magnum PRO consumable system, this nozzle is engineered to extend the life of your welding gun's front-end parts while ensuring precise gas delivery to the weld pool. With a 350A rating, it is robust enough to handle medium to heavy-duty welding applications without compromising on service life.

One of the standout features of this nozzle is its 1/8-inch (3.2 mm) stickout configuration. This recess places the contact tip slightly inside the nozzle, offering protection against short circuits with the workpiece while maintaining excellent gas shielding. The 1/2-inch (12.7 mm) bore ID is versatile enough for a wide range of wire sizes, from .035" up to 5/64", making it a go-to choice for many fabrication shops. The slip-on design utilizes a friction fit with the gas diffuser, ensuring a secure hold that is easy to remove when it's time for cleaning or replacement.

Lincoln Electric has manufactured this nozzle with a nickel-plated finish. This plating is not just for aesthetics; it serves a functional purpose by resisting the adhesion of weld spatter. In high-volume welding environments, spatter buildup can restrict gas flow and cause porosity. The spatter-resistant coating on the KP2742-2-50S helps mitigate this issue, keeping the nozzle cooler and reducing the frequency of interruptions for maintenance. This translates to higher productivity and better weld quality over time.

Compatible with the KP2746-2 gas diffuser, this nozzle integrates perfectly into the Magnum PRO 350A assembly. It represents the high standards of Lincoln Electric's "Copper Plus" technology and expendable design, providing welders with a reliable tool that performs consistently shift after shift.
