KP2746-1-B25 - Lincoln Magnum PRO 350A Thread-On Gas Diffuser (25-Pack)

High-Performance Gas Diffusers for Magnum PRO Systems

The Lincoln Electric KP2746-1-B25 is a bulk package containing 25 high-quality gas diffusers designed specifically for the Magnum PRO series of MIG welding guns. Rated for 350 amps, these diffusers are engineered to withstand the rigors of industrial welding environments while ensuring consistent gas flow and reliable electrical conductivity. The diffuser serves as a critical interface between the gooseneck and the contact tip, playing a vital role in shielding gas distribution and arc stability.

One of the standout engineering features of this model is the inclusion of staggered gas holes. This design choice is not merely aesthetic; it structurally reinforces the component to prevent breakage that can occur from over-torqueing during installation or tip changes. By distributing mechanical stress more evenly, Lincoln Electric has created a consumable that lasts longer and reduces downtime associated with broken parts in the front-end assembly.

In addition to its structural integrity, the KP2746-1 utilizes a coarse thread design for the nozzle connection. This feature is particularly beneficial in high-heat applications where spatter and thermal expansion can cause finer threads to seize. The coarse threads allow for easier removal of the nozzle after repeated use, simplifying maintenance routines and speeding up consumable replacements. This 25-pack configuration (B25) ensures that fabrication shops and heavy manufacturing facilities have an ample supply of these essential components on hand.

Key Technical Benefits:

• Amperage Rating: Optimized for 350A applications, suitable for medium to heavy fabrication.
• Durability: Staggered gas holes mitigate torque-related fractures.
• Maintenance: Coarse threads prevent nozzle seizing and simplify cleaning.
• Compatibility: exclusively designed for the Magnum PRO platform.
