KP2742-2-62F-B25 - Lincoln Magnum PRO 350A Flush Nozzle 5/8 Inch (25-Pack)

High-Performance Magnum PRO Consumables

The Lincoln Electric KP2742-2-62F-B25 is a premium gas nozzle designed specifically for the Magnum PRO series of semi-automatic welding guns. Engineered to meet the rigorous demands of industrial welding, this nozzle features a 350A amperage rating, making it suitable for a wide range of medium to heavy-duty fabrication tasks. The nozzle is constructed from high-quality copper alloy materials that effectively dissipate heat, ensuring longevity even during prolonged welding arcs. This specific model features a 5/8-inch (15.9 mm) inner diameter, which is a standard size for general purpose MIG welding, providing an optimal balance of gas flow and accessibility to tight joints.

Flush Design for Versatility

One of the defining characteristics of the KP2742-2-62F is its flush tip geometry. In this configuration, the contact tip sits flush with the end of the nozzle. This design is highly favored by operators because it offers excellent visibility of the weld puddle and the arc, which is critical for maintaining precision. It also allows for a standard electrical stick-out (ESO), making it a versatile choice for short-circuit, globular, and spray transfer modes. The flush design helps prevent the nozzle from picking up excessive spatter on the interior compared to recessed tips, while still offering better gas shielding than protruding tip setups in drafty conditions.

Convenient Slip-On Installation

Efficiency on the shop floor is paramount, and the slip-on connection of these Magnum PRO nozzles addresses this need. Unlike threaded nozzles that can seize up with spatter or heat expansion, the slip-on design allows for quick removal and installation. This feature significantly reduces downtime during routine maintenance or when clearing spatter buildup. The secure fit ensures the nozzle stays in place during operation but can be easily pulled off when necessary. This 25-pack configuration (B25) is ideal for high-volume production environments where consumable inventory management is key to maintaining workflow continuity.
