The Miller 135425 Contact Tip is a genuine replacement consumable designed specifically for heavy-duty aluminum welding applications. Engineered by Miller Electric, these tips are manufactured to precise tolerances to ensure consistent electrical conductivity and smooth wire feeding. This specific tip is sized for wire diameters ranging from .062 inches to .081 inches, making it a versatile choice for fabricators working with thicker aluminum wires commonly used in industrial manufacturing and shipbuilding.
These contact tips are designed for the classic Miller Spoolmatic® series and XR™ push-pull systems. They are fully compatible with the Spoolmatic 15A and Spoolmatic 30A spool guns, which are industry standards for aluminum MIG welding. Additionally, they fit the Miller XR and XR-M MIG guns. Please note that these are standard, non-threaded tips. They are not compatible with the newer FasTip™ system or Centerfire™ consumables. The slip-fit design allows for rapid changeovers without the need for tools, reducing downtime during critical welding operations.
Aluminum wire is softer and more prone to feeding issues than steel wire. The Miller 135425 tip features a .078-inch bore, which provides the necessary clearance for .062-inch wire to expand slightly as it heats up during the welding process, preventing binding and burnback. The high-quality copper construction ensures excellent heat transfer, keeping the tip cooler and extending its service life. This package contains 10 contact tips, ensuring you have an ample supply on hand for high-volume production environments.
