OVERVIEW

Reliable Performance for Your Miller MDX-250

When you are in the middle of a welding project, the last thing you want is to be fighting with your gun. The Bernard T-A035CH AccuLock S Contact Tip is designed to keep you welding smoothly with your Miller MDX-250 or Bernard BTB MIG gun. These aren't just standard replacement tips; they are part of the AccuLock S system that fixes many of the headaches welders face daily. If you have ever struggled with cross-threading a tip when you are in a hurry, you will appreciate the coarse threads on these tips. They spin on fast and lock tight, so you can get back to laying beads without worrying about the tip rattling loose.

The biggest advantage you will notice is how long these tips last. Because a huge chunk of the tip is tucked away inside the nozzle and diffuser, it stays way cooler than old-school tips that stick out in the heat. Cooler tips mean less spatter sticking to the face and fewer burn-backs clogging up your flow. Plus, the design helps center the wire perfectly every time. Even if your liner trim is a little off—maybe you cut it a hair too short or too long—the AccuLock S tip is forgiving and keeps the wire feeding consistently. This means less bird-nesting at the drive rolls and a smoother arc at the puddle.

This package contains 10 genuine Bernard .035-inch contact tips. They are the exact match for the equipment that came with your Miller MDX-250. Whether you are fabricating in a shop, doing repairs in the field, or running a production line, these tips deliver the durability and consistency you need to produce high-quality welds. Stop wasting time changing out cheap tips that burn up in an hour and switch to the consumables engineered for the job.
