278295 - Miller Power Pin Retaining Clamp

Restore Your Feeder's Performance

Is your MIG gun feeling loose at the feeder connection? Are you noticing erratic arcs or the gun getting unusually hot near the machine? It might be time to check your power pin assembly. The Miller 278295 Clamp, Power Pin Cast is the genuine replacement part you need to lock that connection down tight. As a welder, you know that the connection between your whip and the box is the lifeline of your weld. If that power pin wiggles, you lose voltage, you lose gas coverage, and you eventually lose your patience with poor starts and sputtering arcs.

This isn't just a generic bracket; it is a heavy-duty cast piece designed by Miller to withstand the daily abuse of the shop floor. We all know how often MIG guns get tugged, pulled, and dragged around the booth. All that strain goes directly to the power pin. This cast clamp acts as the anchor, holding the pin block securely in place so your wire feeds straight and your current transfers smoothly. If your existing clamp is cracked from overtightening or worn out from years of service, replacing it is a quick and inexpensive fix that can save you from buying a whole new gun or feeder assembly later on.

Don't settle for makeshift fixes or trying to shim a loose connection. A loose power pin can arc out inside the feeder, ruining expensive drive components. Swapping in a fresh Miller 278295 clamp ensures your machine runs like it did the day it came off the truck. It’s a simple maintenance step that pays off in smoother wire feeding and cooler running equipment. Whether you are doing a full overhaul on an old shop feeder or just fixing a breakdown to get back to burning wire, this OEM part is the right fit for the job. Keep your arc smooth and your connection solid with genuine Miller parts.
