Miller Rubber Bumper Foot Kit - Recessed (Pack of 4)

Protect Your Welder and Workspace

The Miller 239388 Rubber Bumper set is an essential maintenance item for professional welders who value their equipment. Sold as a convenient pack of four, these replacement feet are designed to restore the stability and grip of your Miller welding machine. Over time, the factory-installed rubber feet on portable and shop welders can degrade due to exposure to ozone, heat, and the rough conditions of a welding shop. Worn or missing feet can cause your machine to wobble, slide on smooth concrete, or scratch the finish of your welding cart.

These bumpers are engineered with a recessed center hole (0.188" ID) to accommodate mounting screws or rivets, ensuring the metal hardware sits below the surface of the rubber. This design feature is critical as it prevents the metal fastener from making contact with the surface the welder sits on, thereby preventing scratches on customer floors, workbenches, or truck beds. With an outer diameter of 0.875 inches and a height of 0.39 inches, they provide a compact yet robust cushion that withstands the heavy weight of transformer-based or inverter power sources.

Beyond surface protection, these rubber isolators play a key role in machine performance. They act as shock absorbers, dampening the vibration caused by cooling fans and internal electronics. This isolation helps protect sensitive circuit boards from high-frequency vibrations that can occur in industrial environments. When a welder sits directly on a hard surface without these bumpers, the noise level increases, and the risk of the machine "walking" due to vibration rises.

This kit is a genuine Miller Electric part, guaranteeing fitment and material quality superior to generic hardware store rubber feet. The rubber compound is resistant to oil and shop chemicals, ensuring a long service life even in greasy environments. Keep a pack in your maintenance drawer to quickly address missing feet and keep your Miller welder sitting level, secure, and ready for action.
