KP2742-1-38F-B25 - Lincoln Magnum PRO 350A Flush MIG Nozzle, 3/8 Inch Bore, 25-Pack

Lincoln Electric KP2742-1-38F-B25 Magnum PRO Nozzle (25-Pack)

The Lincoln Electric KP2742-1-38F-B25 is a bulk package of high-performance gas nozzles designed for the Magnum PRO 350A series of semi-automatic welding guns. This 25-pack is specifically curated for industrial environments where uptime and consumable availability are critical. Each nozzle features a flush tip geometry, meaning the contact tip sits flush with the end of the nozzle. This configuration is widely favored for its versatility, offering a balanced combination of gas shielding and arc visibility, making it suitable for a broad range of short-circuit and spray transfer applications.

With a 3/8-inch (9.5 mm) inner diameter, this nozzle is engineered for tighter access applications where standard 1/2-inch or 5/8-inch nozzles might be too bulky. Despite the narrower bore, it maintains excellent gas flow characteristics to prevent porosity. The nozzle is rated for 350 amps, making it robust enough for medium-to-heavy fabrication tasks. The thread-on design is a key feature of the Magnum PRO line, ensuring a solid mechanical connection that promotes superior thermal conductivity. This helps dissipate heat away from the front end of the gun, extending the life of both the nozzle and the contact tip.

Fabricators and MRO professionals rely on Lincoln Electric's Magnum PRO consumables for their durability and consistency. The copper alloy construction resists spatter adhesion, reducing the frequency of cleaning intervals. By purchasing the B25 bulk pack, shops can significantly reduce their cost per unit and ensure that operators always have fresh consumables on hand, minimizing downtime associated with worn-out equipment.
