T-A045CH - Bernard AccuLock S .045 Contact Tips (10-Pack) for MDX-250 & BTB Guns

Experience Smoother Feeding with AccuLock S Contact Tips

Every welder knows the frustration of a burnback or a birdnest right in the middle of a critical pass. Often, these issues stem from a liner that was trimmed just a fraction of an inch too short or has worked itself loose over time. The Bernard AccuLock S .045 Contact Tip (T-A045CH) is designed to eliminate that headache. If you are running a Miller MDX-250 or a Bernard BTB MIG gun, upgrading to these tips means you are upgrading your entire wire feeding path. The AccuLock S system actually locks your liner in place when you tighten the tip, fixing those small trim errors that usually cause big problems.

Built for the demands of the shop floor, these .045-inch tips are made from durable industrial copper that withstands heat and wear better than standard light-duty consumables. The increased contact area ensures your machine's power is transferred efficiently to the wire, giving you a crisp, consistent arc start after start. Whether you are fabricating structural steel, working on heavy equipment, or performing general repairs, the stability provided by these tips allows you to focus on your puddle control rather than fighting your gun.

This 10-pack ensures you are ready for the long haul. Changing them out is quick and easy, thanks to the coarse thread design that prevents cross-threading and speeds up replacement. By centering the liner and the tip perfectly within the nozzle, you also get better gas coverage, which means cleaner welds with less spatter to grind off later. Don't let poor consumables hold back your productivity; switch to the AccuLock S T-A045CH and feel the difference in your wire feed.
