268849 - Miller .047 Aluminum Drive Roll Kit for XR Control Feeders

Optimize Aluminum Feeding with Miller 268849 Drive Rolls

Achieving the perfect aluminum weld starts with consistent wire delivery, and the Miller 268849 Drive Roll Kit is engineered to deliver exactly that. Specifically designed for .047-inch aluminum wire and compatible with Miller XR Control feeders, this kit features polished U-groove drive rolls. Unlike knurled rolls used for flux-cored wire or V-groove rolls for hard steel, these polished U-groove rolls cradle soft aluminum wire, providing positive traction without biting into the metal. This prevents the creation of metal shavings that can accumulate in the gun liner and cause erratic arcs or burn-backs.

The XR Control system is a workhorse in the aluminum welding world, often used in push-pull setups for extended reach. The drive rolls are the heart of this system's ability to push wire smoothly. If your current rolls are worn or incorrect for the wire size, you may experience slipping or deformation of the wire. Installing the 268849 kit restores the precise grip needed for stable arc performance. This is particularly important when welding thin-gauge aluminum where arc stability is paramount to prevent burn-through.

Welders know that equipment maintenance is key to performance. Replacing your drive rolls is a standard maintenance procedure that ensures your expensive wire feeder continues to perform like new. This kit comes directly from Miller, ensuring that the materials and machining meet the high standards expected by professional welders. Don't let poor wire feeding compromise your welds; upgrade to the correct drive rolls for your application.

Technical Advantages:

• Polished U-Groove: Minimizes friction and eliminates wire shaving.
• Precision Fit: Designed exclusively for the XR Control chassis.
• Consistent Feeding: vital for pulse MIG and spray transfer modes common in aluminum welding.
