KP2747-1-B25 - Lincoln Electric Magnum PRO 550A Thread-On Gas Diffuser (25-Pack)

Reliable Diffusers for Your Magnum PRO Gun

When you are pushing 550 amps on a heavy structural job, the last thing you want is your front-end consumables failing. The Lincoln Electric KP2747-1-B25 gas diffuser is built to take the heat. Designed for the Magnum PRO series, this diffuser isn't just a holder for your tip; it's engineered to keep you welding longer with less downtime for maintenance. This 25-pack ensures your tool crib is stocked and your welders aren't waiting on parts.

We know the frustration of trying to twist off a nozzle that has fused itself to the diffuser. Lincoln addressed this with a coarse thread design on the KP2747-1. These threads are much more forgiving than standard fine threads, resisting the seizing caused by heat expansion and spatter buildup. This means when it's time to clean your nozzle or change a tip, you can get the nozzle off without fighting it, saving your wrists and your patience.

Another common failure point on diffusers is snapping off inside the gun or twisting apart when you crank down on a contact tip. Lincoln's staggered gas hole design reinforces the structural integrity of the diffuser. By offsetting the gas ports, the metal remains stronger, preventing the breakage from over-torqueing that plagues cheaper alternatives. This robust design ensures that the gas flow remains smooth and laminar, protecting your weld pool from porosity.

This diffuser is a thread-on style, which provides a solid mechanical and electrical connection. It transfers current efficiently to the contact tip, helping to maintain a stable arc even at the top end of the amperage range. Whether you are welding thick plate, heavy equipment, or pipe, these diffusers provide the reliability professional welders demand from their Lincoln Electric gear.
