058853 - Miller .047 Aluminum Intermediate Wire Guide

Precision Wire Control for Aluminum MIG Welding

Maximize the performance of your Miller wire feeder with the Miller 058853 Guide, Wire Intermediate .047 Al. This specialized component is designed specifically to address the difficulties associated with feeding .047-inch (1.2 mm) aluminum welding wire. Unlike steel, aluminum has low column strength, meaning it cannot be pushed through a gun cable with the same force without support. This intermediate guide sits centrally in the drive roll assembly, supporting the wire as it transitions through the feed mechanism, effectively eliminating the space where the wire could otherwise buckle or tangle.

The geometry of this guide is critical. It features an internal bore perfectly sized for .047" wire, preventing the wire from wandering while minimizing friction. This is essential for maintaining a constant wire feed speed (WFS), which directly correlates to amperage and penetration in MIG welding. If the wire slips or drags, the arc becomes erratic. By using the correct intermediate guide, you ensure that the drive rolls transfer force efficiently to the wire, resulting in consistent arc starts and smooth bead profiles.

This is a genuine Miller Electric replacement part, ensuring compatibility with specific Miller wire feeders and Millermatic machines equipped for aluminum. Professional welders know that converting a machine for aluminum requires more than just changing the spool; the entire feed path must be optimized. This includes U-groove drive rolls, nylon liners, and crucially, the correct inlet and intermediate guides. The 058853 is the correct choice for the intermediate position when running .047" Al wire.

Don't let poor feeding ruin your aluminum welds. Worn or incorrect guides are a leading cause of burn-back and bird-nesting. Ensure your equipment is set up for success with the Miller 058853. It is a small investment that prevents major frustration and rework, keeping your welding operations running at peak efficiency.
