018640 - Miller RFC Foot Control Contact Brush Set (2-Pack)

Fix Erratic Amperage Control

Is your trusty Miller foot pedal acting up? If you are experiencing jumpy amperage, dead spots where the arc loses power, or a gritty feeling when you press down on the pedal, the issue might be as simple as a worn contact brush. The Miller 018640 Brush, Contact Elect RFC Foot Controls (2 Pack) is the genuine solution to get your pedal back to factory-fresh performance. Don't let a small maintenance part ruin your welds or frustrate your workflow.

Why Genuine Miller Parts Matter

When you are in the middle of a critical TIG weld, the last thing you need is your equipment fighting you. The foot control is your connection to the puddle, allowing you to feather the heat as you add filler or taper off at the end of a bead. The internal components of the RFC series pedals are built like tanks, but the contact brushes are designed to be consumable items. They take the brunt of the friction to protect the more expensive electrical windings. Replacing them with genuine Miller 018640 brushes ensures you are using materials that match the original engineering, guaranteeing smooth electrical contact without damaging the internal coil.

Cost-Effective Repair

Replacing a full industrial foot pedal can be a significant expense. Often, welders assume a pedal is "broken" when it simply needs a tune-up. This 2-pack of contact brushes is an incredibly cost-effective way to revive an older RFC-23A or similar pedal. Instead of discarding a heavy-duty piece of American-made equipment, a few minutes of maintenance with these brushes can give it a new lease on life. It is a smart investment for any shop running classic Miller TIG machines.

Get Back to Welding

Symptoms of bad brushes include flickering arcs, inability to reach full amperage, or sudden surges in power. If you notice these signs, check your pedal's internals. If the brushes look worn down, chipped, or are making poor contact, this kit is exactly what you need. Keep a pack in your maintenance drawer so you never have to stop production due to a minor wear part. With Miller's quality assurance, you can trust these brushes to provide consistent, reliable control for years to come.
