Big Blue 400 Pro (Kubota)

Designed with the professional in mind, the Big Blue 400 Pro is built for ease of use, reliability and fuel economy across demanding industrial welding environments.

01

Heavy-Duty Performance

Powered by the low-speed Kubota V1505 industrial diesel engine, the Big Blue 400 Pro is designed for long operational life with up to 10,000 hours before major overhaul.

Built for industrial applications worldwide, the system is backed by global support and service while delivering dependable site performance and improved fuel economy.

Quiet operation improves worksite communication and safety, while HD powder coat protection provides enhanced resistance against rust and corrosion.

02

Advanced Welding Features

Miller’s proprietary Dynamic DIG automatically adjusts current required to clear a short, delivering a smoother and more consistent arc tailored to application, material and welder technique.

Adaptive Hot Start™ improves stick electrode starts without creating inclusions, while Infinite Arc Control allows easier fine tuning for difficult welding applications.

Lift-Arc™ TIG technology minimises electrode and work contamination without requiring high frequency arc starting.

03

Smart Controls & Operator Safety

Digital meters with SunVision technology provide clear parameter visibility even in direct sunlight, while simple-to-set controls streamline operation without complex setup procedures.

The industrial USB port enables software updates and machine diagnostics downloads for improved maintenance and operational tracking.

Additional features including Low OCV Stick (VRD), Auto Remote Sense (ARS), automatic idle, thermal overload protection and engine block heater improve safety, usability and productivity on site.
