4235 - Bernard 4235 MIG Gun Head Assembly 200A

Reliable Performance with the Bernard 4235 Diffuser

When you are in the middle of a job, the last thing you need is your MIG gun acting up. The Bernard 4235 Head Assembly is the workhorse part that keeps your 200 Amp torch firing correctly. Often called a gas diffuser or tip holder, this little brass part does a lot of heavy lifting. It holds your contact tip in place and makes sure your shielding gas comes out smooth and steady. If you've ever dealt with sputtering arcs or porosity in your welds, a worn-out diffuser is often the culprit. Swapping in a fresh Bernard 4235 can instantly clean up your arc and get you back to laying down smooth beads.

Built tough for the shop environment, this head assembly is made from solid brass. Why does that matter? Brass handles heat better than cheaper metals and doesn't strip out as easily when you are changing tips on the fly. We all know how frustrating it is when a contact tip won't thread in smoothly or, worse, falls out while you are welding. The 4235 features precision threads that grip your tip tight, ensuring the electricity flows efficiently from the gun to the wire. Good electrical contact means a hotter, more stable arc and less spatter to clean up later.

Gas coverage is another huge factor in weld quality. The holes in the 4235 diffuser are designed to spread the gas out evenly inside the nozzle. This creates a nice blanket of gas over your weld puddle, keeping the air out and preventing those annoying pinholes. Whether you are running CO2 or a mixed gas, this diffuser helps you get the most out of your tank by directing the flow exactly where it needs to go.

Installation is a breeze—just unscrew the old one and thread this one on. It fits standard Bernard 200 Amp guns, making it a perfect spare part to keep in your toolbox. Don't let a ten-dollar part hold up a thousand-dollar job. Keep your front end fresh with the Bernard 4235 and trust that your equipment is ready to perform whenever you pull the trigger.
