411-4 - Bernard 411-4 Lock-On Head for Elliptical Consumables

Keep Your Bernard Gun Running Smooth with the 411-4 Head

If you are running a Bernard MIG gun with Elliptical tips, you know that the head (or housing) is the backbone of your front end. The Bernard 411-4 Lock-On Housing is the genuine replacement part you need when your old head gets battered, stripped, or clogged with spatter. Designed for the welder who needs to keep the arc on, this head features Bernard's trusted Lock-On technology. Forget about wrestling with seized threaded nozzles; this head allows your Lock-On nozzle to snap securely into place and stay there, even when you are dragging the gun across the shop floor or banging spatter off the rim.

This housing isn't just about holding the nozzle; it's about performance. Made from heavy-duty brass, it handles the heat of high-amperage welding without melting down or losing conductivity. It provides a solid, threaded seat for your Elliptical contact tips, ensuring the current gets to the wire exactly where it needs to. A worn-out head can cause erratic arcs, poor gas coverage, and loose tips that ruin your welds. Swapping in a fresh 411-4 restores that crisp, consistent performance you expect from a Bernard gun.

Installation is straightforward—simply unscrew your old head from the gooseneck and thread this one on. It fits perfectly on Bernard Q-Guns, S-Guns, and T-Guns configured for the Elliptical system. Whether you are fabricating heavy structural steel or doing production MIG work, having a fresh head ensures your gas flows smooth and your tip stays cool. Don't let a beat-up front end slow you down; grab a 411-4 and get back to laying dimes.
