Miller AccuLock MDX Contact Tips T-M030 10-Pack

These Miller Electric T-M030 contact tips suit MIG welders using the AccuLock MDX system. They accept solid or flux-cored wire up to 0.03 inch diameter and handle up to 250 A. The threaded design fits MDX-100 and MDX-250 series guns. Welders running compatible Miller machines will find these tips match their existing consumables.

Threaded PK10 bundle simplifies consumable

The ten-piece pack keeps spare tips on hand for production runs or field repairs. Standard-duty rating covers typical fabrication and maintenance tasks. Threaded connection allows quick change-outs without tools. Compatible gas diffusers D-M100 and D-M250 work with the same tip series, reducing part variety on the bench.

Verify gun model and wire size before ordering

These tips only fit AccuLock MDX guns listed in the compatibility data. Machines outside the MDX-100, MDX-250 or MDX-250 EZ-Select lines will not accept the threaded T-M030 profile. Wire larger than 0.03 inch requires a different tip bore. California Proposition 65 warnings apply to this product.

Questions about this item

How often will the T-M030 contact tip need replacing during heavy MIG welding?

Replace the tip when the .03 in wire feeds inconsistently or the tip orifice wears out; each pack supplies 10 tips for quick changeovers.

What is the first limit reached when running the tip at its 250 A maximum current?

The 250 A duty rating is the ceiling; exceeding it accelerates tip wear and can degrade weld quality.

How hot does the threaded T-M030 tip get during all-day MIG welding at 250 A?

The tip operates at the 250 A standard-duty rating; expect elevated temperature consistent with continuous high-amperage MIG welding.
