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

Genuine Miller 223017 FasTip Contact Tips (10-Pack)

Keep your Miller MIG guns performing at their peak with the Miller 223017 FasTip Contact Tips. Designed for versatility and durability, these tips are a must-have for welders tackling both steel and aluminum projects. The unique sizing of this tip makes it the perfect match for .040-inch solid steel wire, while also serving as the designated tip for .035-inch aluminum wire. Aluminum expands more than steel as it heats up, requiring slightly more clearance in the contact tip bore to prevent seizing and burn-backs. Miller has engineered the 223017 to provide that exact tolerance, ensuring your aluminum wire feeds smoothly through your Spoolmatic or XR gun without snagging.

The FasTip system is a favorite among professional welders for its user-friendly design. Unlike standard threaded tips that can seize or strip, FasTips are designed for quick, secure installation, allowing you to swap out consumables in seconds and get back to welding. This efficiency is paired with rugged construction; the high-quality copper alloy resists wear and withstands the intense heat of high-amperage welding. With a .312-inch outside diameter, these tips fit perfectly into the diffusers of Roughneck C-Series guns and the popular Spoolmatic 15A and 30A spool guns, maintaining the correct stick-out and gas flow dynamics.

Sold in a pack of 10, these contact tips offer excellent value and convenience for busy fabrication shops. Running out of contact tips in the middle of a job is a welder's nightmare, so keeping a fresh pack of genuine Miller 223017s in your toolbox ensures you are always ready. Whether you are fabricating aluminum boat hulls, repairing truck bodies, or performing general steel maintenance, these tips deliver the consistent arc starts and stable performance that Miller Electric is known for. Don't compromise on your consumables—choose genuine Miller FasTips for reliable, high-quality welds every time.
