KP2742-1-50F - Lincoln Magnum PRO 350A MIG Nozzle, Flush, 1/2 in ID, Thread-On

Lincoln Electric Magnum PRO 350A Thread-On Nozzle

The Lincoln Electric KP2742-1-50F is a premium gas nozzle engineered for the Magnum PRO 350A series of semi-automatic welding guns. Designed to meet the rigorous demands of industrial fabrication, this nozzle features a 350-amp rating and a 1/2-inch (12.7 mm) inner diameter bore. The unit utilizes a thread-on connection mechanism, which provides superior concentricity compared to slip-on models, ensuring consistent gas coverage and precise contact tip alignment. This specific model offers a flush tip relationship, where the contact tip sits flush with the nozzle exit, making it versatile for a wide range of standard welding applications.

Durability and maintenance efficiency are core components of the Magnum PRO line. The KP2742-1-50F is constructed with high-quality materials and finished with a nickel plating. This plating is essential for professional environments as it resists spatter adhesion, keeping the nozzle clean and reducing the frequency of cleaning intervals. Additionally, the nozzle is designed with coarse threads. Unlike fine threads that can easily cross-thread or seize due to thermal expansion and contraction, these coarse threads ensure the nozzle remains easy to unscrew and replace, even after repeated exposure to high welding temperatures.

This consumable is a critical component for maintaining the thermal balance of your welding gun. By effectively channeling shielding gas and protecting the front-end consumables, it helps keep the welding gun cool during prolonged use. It is strictly compatible with 350A Thread-On Diffusers and is part of the larger Magnum PRO ecosystem, allowing for modular configuration with various contact tips and diffusers to suit specific project requirements.
