0559351280 - ESAB 200A MIG Gun Gas Diffuser

Keep Your Arc Smooth and Your Welds Clean

Every welder knows that a good weld starts with good gas coverage. If you are experiencing porosity, erratic arcs, or excessive spatter, your gas diffuser might be the culprit. The ESAB Shield Gas Distributor 200A (0559351280) is the genuine replacement part you need to get your MIG gun back in top fighting shape. Designed specifically for ESAB 200-amp class torches, this little brass component plays a huge role in the quality of your work.

Think of the gas distributor as the heart of your torch's front end. It does two main jobs: it holds your contact tip securely in place, and it breaks up the shielding gas flow so it comes out smooth and even. When a diffuser gets clogged with spatter or the threads get stripped from constant tip changes, your gas coverage suffers. This can let air into your weld puddle, causing those annoying pinholes that no one wants to grind out. Swapping in a fresh ESAB distributor ensures that your shielding gas creates a perfect protective bubble around your molten pool.

Built tough to handle the heat, this distributor is made from durable brass that stands up to the thermal shock of day-to-day welding. It screws on easily and stays tight, giving you a solid electrical connection to the contact tip. This means better arc starts and less troubleshooting in the middle of a job. Whether you are working in a fabrication shop, a garage, or on a repair site, having a reliable front-end assembly is key to productivity.

Don't let a worn-out five-dollar part ruin a thousand-dollar project. Keep a few of these ESAB 200A gas distributors in your toolbox. They are compatible with standard ESAB PSF series setups and are designed to take the abuse of real-world welding. Simply unscrew the old one, clean the threads on the neck, and spin this new one on. You'll notice the difference in arc stability and weld cleanliness immediately. Stick with OEM parts to guarantee the fit and performance your torch was built to deliver.
