D-A2-C - Bernard AccuLock S Slip-On Gas Diffuser (10-Pack)

Smoother Welds with the AccuLock S Slip-On Diffuser

If you are running a Bernard BTB gun or a Miller MDX-250, you know that the front-end consumables make or break your day. The Bernard D-A2-C AccuLock S Gas Diffuser is built to make your life easier and your welds cleaner. This diffuser is the heart of the AccuLock S system, designed to keep your contact tip perfectly centered. When your tip is centered, your wire feeds straighter, your arc is more stable, and you get less spatter sticking to your nozzle. It’s a small part that makes a huge difference in how your gun handles.

The "Slip-On" feature is a game-changer for anyone who hates wrestling with threaded nozzles. With the D-A2-C, you simply slide your nozzle on and off. There are no threads to cross, no seizing up from heat, and no wasting time when you need to pull the nozzle for a quick spatter clean-out. The brass construction is tough enough to handle the heat of long welds, and the gas ports are designed to give you a smooth, even shield of gas, protecting your puddle even when you're maneuvering in tight corners.

This pack comes with 10 diffusers, so you can keep a stash in your toolbox or supply locker. We all know diffusers can get clogged or damaged over time, especially if you are pushing high amps or dealing with a lot of reflective heat. Swapping out a worn diffuser for a fresh D-A2-C can instantly restore your gas coverage and arc stability. Whether you are fabricating structural steel or doing production MIG work, these diffusers help keep your downtime low and your weld quality high.
