278413 - Miller Big Blue 400 Pro Kubota Rating Plate Decal

Keep Your Rig Professional with the Miller 278413 Rating Card

Your welding rig is your livelihood, and keeping it in top shape means more than just changing the oil and checking the leads. The Miller 278413 Label, Rating Card is the direct replacement sticker for the Big Blue 400 Pro (Kubota). If your current rating plate has been blasted by the sun, scratched up by debris, or pressure-washed into oblivion, this is the part you need to get your machine looking right again.

Why does a sticker matter? The rating card tells you exactly what your machine can handle—amperage, voltage, and duty cycle at a glance. When you are out on a job site, having clear, readable specs prevents guessing games and helps you dial in the machine correctly for the task at hand. It also shows clients and inspectors that you take care of your equipment. A beat-up machine with missing labels looks neglected; a machine with crisp, clear decals looks like it belongs to a pro who cares about quality.

This isn't a generic sticker that might fit. This is the official Miller OEM part, cut to the exact size for the Big Blue 400 Pro panel. It uses heavy-duty industrial adhesive that grabs onto the metal and stays put, rain or shine. It is designed to handle the heat, the cold, and the vibration of a running diesel engine without curling up at the edges. Because it is specific to the Kubota model, all the numbers on it will be accurate for your specific power source.

Installation is straightforward: just scrape off the old remnants, clean the surface thoroughly with a degreaser to remove any oil or residue, let it dry, and slap this new one on. It’s a small detail that makes a big difference in the overall condition and resale value of your welder. Don't let a faded label be the weak link in your setup.
