KP3359-1-50F-B25 - Lincoln Magnum PRO 350A Extended Reach Nozzle 1/2 Inch Bore Flush Tip 25-Pack

Industrial Grade Extended Reach MIG Nozzles

The Lincoln Electric KP3359-1-50F-B25 is a specialized gas nozzle designed for the Magnum PRO series of semi-automatic welding guns. Engineered for professional fabrication environments, this nozzle features a 350A amperage rating, making it suitable for a wide range of medium to heavy-duty welding applications. The defining characteristic of this specific model is its extended reach design, which provides an additional 1.5 inches of length compared to standard nozzles. This geometric advantage is critical for manufacturing sectors where complex assemblies require welding in recessed areas, corners, or obstructed zones that standard gun configurations cannot effectively reach.

Constructed from high-quality copper alloy, these nozzles are built to withstand the intense thermal cycling inherent in 350A welding procedures. The 1/2-inch (12.7 mm) inner diameter ensures a focused and adequate shielding gas envelope, protecting the weld pool from atmospheric contamination even when reaching into deep joints. The "Flush" specification (1/8 in / 3.2 mm) indicates the relationship between the contact tip and the nozzle exit, providing a balance between visibility and gas coverage. By utilizing the Magnum PRO consumable platform, operators benefit from Lincoln Electric's focus on component longevity and performance consistency.

This product is supplied in a bulk package of 25 units, designated by the "-B25" suffix. This packaging configuration is optimized for industrial supply chains and high-volume workshops, ensuring that welding stations remain stocked with essential consumables to minimize downtime. The nozzle's robust design resists spatter adhesion, although the use of anti-spatter compounds is recommended to further extend service life. Whether used in automotive manufacturing, structural steel fabrication, or general heavy equipment repair, the KP3359-1-50F-B25 offers the precision and reach necessary for high-quality weld deposition.
