223017 - Miller 223017 FasTip Contact Tips .040/.035AL (10-Pack)

Precision Miller FasTip Contact Tips for Aluminum and Steel

The Miller 223017 FasTip Contact Tips are engineered to meet the rigorous demands of industrial MIG welding, offering a versatile solution for fabricators working with multiple material types. These genuine Miller consumables are specifically designed with a bore tolerance that accommodates .040-inch hard wires (such as mild steel or stainless) while simultaneously providing the ideal clearance for .035-inch aluminum wires. This dual-compatibility is particularly beneficial for shops that utilize Miller Spoolmatic or XR Push-Pull systems, where aluminum welding is a primary application. The tip's internal geometry ensures smooth wire feeding, reducing the friction that often leads to bird-nesting in softer aluminum alloys.

Constructed from high-conductivity copper, these FasTip contact tips maximize electrical transfer to the welding wire, resulting in a stable, consistent arc. The .312-inch outside diameter is a standard size for the Roughneck C-Series and compatible spool guns, ensuring a proper fit within the gas nozzle for optimal shielding gas coverage. The FasTip design itself is renowned for its ease of installation; the interface allows for rapid tip changes without the risk of cross-threading that can occur with traditional threaded tips. This feature is critical in high-volume production environments where downtime must be kept to a minimum.

These tips are essential components for maintaining the performance of Miller's advanced wire feeding systems. Whether you are operating a Spoolmatic 15A/30A for on-site aluminum repairs or an XR Push-Pull gun for long-distance wire feeding, the 223017 contact tip provides the reliability professional welders expect. Supplied in a convenient package of 10, these tips ensure you have the necessary inventory to maintain continuous operations. By using genuine Miller parts, operators safeguard the longevity of their MIG guns and ensure the integrity of their welds through consistent electrical contact and superior heat dissipation.
