135429 - Miller 135429 Contact Tip .047 (3/64) for Spoolmatic & XR Guns (10-Pack)

Genuine Miller Performance for Spoolmatic & XR Systems

Maximize the performance of your Miller aluminum welding setup with the Miller 135429 Contact Tip (10-Pack). Designed specifically for 3/64" (0.047") wire, these contact tips are the standard replacement part for some of the industry's most trusted aluminum guns, including the Spoolmatic 15, Spoolmatic 30A, and the heavy-duty XR series push-pull systems. When welding aluminum, the interface between the wire and the contact tip is the final critical point of current transfer; using genuine Miller consumables ensures that this transfer is efficient and consistent.

Precision Engineering for Soft Wire

Feeding aluminum wire presents unique challenges due to its low column strength. The Miller 135429 tip is engineered with the correct ID clearance for 0.047" wire, preventing the common issues associated with thermal expansion. If a tip is too tight, the wire jams when the tip heats up; if it is too loose, the arc wanders. Miller's precision manufacturing strikes the perfect balance, providing a stable arc and smooth wire delivery that professional welders demand. The copper construction offers excellent thermal conductivity, helping to dissipate heat quickly and prolong the life of the tip even under high-amperage spray transfer conditions.

Compatibility and Value

These contact tips are essential for anyone operating Miller's push-pull or spool gun solutions. Whether you are repairing aluminum truck beds or fabricating intricate aerospace components, the 135429 tip delivers the reliability you need. Sold in a convenient pack of 10, this SKU ensures you aren't caught empty-handed in the middle of a job. Don't compromise your weld quality with inferior aftermarket parts; stick to the specs your machine was built for with genuine Miller contact tips.
