15641145 - Tweco 56-W Gas Diffuser / Contact Tip Retainer (Pack of 5)

Reliable Arc Performance with Tweco 56-W Diffusers

When you are in the middle of a heavy fabrication job, the last thing you need is a stuttering arc or poor gas coverage. The Tweco 56-W Gas Diffuser (1564-1145) is built to keep your MIG gun firing smoothly. Acting as the anchor for your contact tip, this solid brass retainer ensures that the welding current transfers efficiently from the gun liner to the wire, giving you the consistent heat and penetration you need for structural welds.

Designed specifically for the workhorses of the industry—the Tweco Spray Master 450 and the legendary #5 gun—this diffuser stands up to high-amperage heat. Its robust construction resists deformation, ensuring that your contact tips screw in tightly every time. Loose tips lead to arcing inside the diffuser and premature failure; the 56-W's precision threading helps prevent this, saving you downtime and frustration.

Beyond holding the tip, the 56-W plays a vital role in shielding your weld. Its gas ports are engineered to smooth out the turbulence of the shielding gas as it exits the nozzle, creating a clean envelope of protection around your puddle. Whether you are running straight CO2 or an Argon mix, this diffuser helps you lay down clean, porosity-free beads. Sold in a convenient pack of 5, this kit ensures you always have a spare on hand when it's time for a change-out.
