KP2742-1-62S - Lincoln Electric Magnum PRO 350A Thread-On MIG Nozzle, 5/8" Bore, 1/8" Stickout

Maximize Performance with Genuine Lincoln Parts

Elevate the reliability of your welding operations with the Lincoln Electric KP2742-1-62S Thread-On MIG Nozzle. Designed as a direct replacement for the Magnum® PRO 350A welding gun platform, this nozzle is an essential consumable for welders demanding precision and durability. In the harsh environment of industrial welding, the quality of your front-end consumables can dictate the efficiency of your production line. This nozzle is built to deliver consistent shielding gas coverage, ensuring defect-free welds and reducing the need for costly rework.

Advanced Design Features

The KP2742-1-62S is characterized by its 5/8-inch (15.9 mm) bore and 1/8-inch (3.2 mm) stickout. The 1/8-inch stickout is particularly advantageous for maintaining a consistent electrical stickout (ESO) and protecting the contact tip from spatter bridging. This nozzle is compatible with wire sizes ranging from .035" to 5/64", making it versatile for various material thicknesses and welding positions. The thread-on design ensures a secure mechanical connection to the diffuser, preventing the nozzle from becoming loose during operation and eliminating gas leaks that could compromise the weld integrity.

Built for the Industrial Environment

Heat and spatter are the enemies of welding consumables. Lincoln Electric addresses these challenges with robust construction and smart materials. The KP2742-1-62S features a nickel-plated finish over a high-conductivity copper alloy body. This plating acts as a shield against molten spatter, preventing it from fusing to the nozzle walls. This not only extends the life of the part but also ensures that gas flow remains laminar and uninterrupted. Furthermore, the nozzle incorporates Lincoln's signature coarse thread design. Unlike fine threads that can easily gall or seize after exposure to extreme heat, these coarse threads allow for easy removal and replacement, even after the gun has been subjected to high amperage loads for extended periods.

Why Choose Magnum PRO Consumables?

• System Integrity: Designed to work seamlessly with Magnum PRO 350A contact tips and diffusers.
• Thermal Efficiency: Helps dissipate heat to keep the gun running cooler.
• Reduced Downtime: Anti-seize threads and spatter-resistant plating speed up maintenance.
• Quality Assurance: Genuine Lincoln Electric parts guarantee performance to factory specifications.
