0559210075 - ESAB PSF Series Gas Distributor 400A

Keep Your ESAB Torch Running Smoothly

If you are running an ESAB PSF series MIG gun and noticing inconsistent gas coverage or spatter buildup affecting your nozzle fit, it might be time to replace your gas distributor. The ESAB 0559210075 Shield Gas Distributor is the standard 400A replacement part designed to get your torch back to factory performance. It fits securely into the neck of your gun and holds your contact tip in place, ensuring the current transfer is solid and the gas flows exactly where it needs to go.

Welding at 400 amps generates a lot of heat, and your front-end consumables take the brunt of it. This distributor is built tough to handle that heat without warping or seizing up. A worn-out diffuser can cause turbulent gas flow, leading to porosity in your welds—a headache no welder wants to deal with. By swapping in a fresh distributor, you ensure that your shielding gas comes out in a smooth, even stream, protecting your puddle and helping you lay down high-quality beads.

This part is compatible with popular ESAB models like the PSF 405 and PSF 410W. It's a quick swap that can save you downtime later. Whether you are fabricating heavy structural steel or doing production MIG work, keeping a spare 0559210075 in your toolbox ensures you aren't left scrambling when a part wears out. Trust genuine ESAB parts to fit right the first time and last longer under the hood.
