135430 - Miller .035 Aluminum Contact Tip for Spoolmatic 30A (10-Pack)

Reliable Feeding for Your Spoolmatic Gun

If you are welding aluminum with a Miller Spoolmatic or XR system, you know that smooth wire feeding is the key to a good bead. The Miller 135430 Contact Tip is designed to keep your operation running without a hitch. These tips are sized for .035-inch wire but feature a specific .052-inch ID (inner diameter). This extra clearance is intentional—it gives aluminum wire the room it needs to expand as it heats up, preventing the wire from dragging or sticking inside the tip. This simple feature drastically reduces burnback and frustration, letting you focus on your puddle rather than troubleshooting your gun.

These tips are the non-threaded, slip-in style found on Spoolmatic 15A, Spoolmatic 30A, and XR-Edge guns. They slide directly into the gas diffuser and are held in place by the nozzle assembly, making them incredibly fast to swap out when you are in the middle of a job. Don't let a worn-out tip ruin your welds or cause erratic arc issues. A fresh contact tip ensures positive electrical transfer to the wire, resulting in cleaner starts and less spatter.

Sold in a convenient pack of 10, these genuine Miller parts are a must-have for any shop using older style Miller aluminum guns. They are built to handle the heat and provide consistent performance shift after shift. Check your gun model to ensure it uses the slip-fit style tips (not the threaded FasTip) and get back to welding with confidence.
