907732001 - Miller Big Blue 400 Pro Kubota Diesel Welder with ArcReach

Unmatched Reliability and Control on the Jobsite

The Miller Big Blue 400 Pro (Kubota) with ArcReach technology represents the pinnacle of industrial diesel welding performance. Designed for professional welders who demand reliability, fuel economy, and ease of use, this machine is built to withstand the harshest environments while delivering consistent, high-quality welds. At its heart lies the heavy-duty, low-speed Kubota V1505 industrial diesel engine, a powerhouse renowned globally for its durability and designed to run for 10,000 hours before requiring a major overhaul. This ensures that your investment keeps working as hard as you do, project after project.

One of the standout features of this model is the integrated ArcReach technology. In large industrial sites or complex construction zones, walking back to the power source to adjust voltage or amperage wastes valuable time and increases safety risks. ArcReach solves this by allowing the operator to make parameter adjustments directly from the wire feeder or remote, using the existing weld cables to communicate with the generator. This eliminates the need for fragile and expensive control cords, reduces trip hazards, and significantly increases arc-on time.

Beyond its welding capabilities, the Big Blue 400 Pro serves as a robust power generator, providing 12,000 watts of peak power and 10,000 watts of continuous power. This allows you to run tools, lights, and other jobsite essentials simultaneously without compromising weld performance. The machine also features an industrial USB port for quick software updates and diagnostic log retrieval, ensuring your equipment stays up to date with the latest Miller innovations. With its HD powder coat finish and zinc-rich primer, the chassis is built to resist rust and corrosion, making it a long-lasting asset for any fleet.
