The Big Blue 400 Eco Pro is a
rugged, compact, fuel-efficient
diesel welder/generator that’s
Eco-friendly and Eco-nomical.
Mitsubishi S4L2 4-cylinder diesel.
Heavy-duty industrial engine is
designed to operate over 10,000 hours
before the first basic overhaul. Backed
by worldwide support and service.
Superior arc performance
• Factory-preset DIG settings (Stick)
• Hot Start ™ (Stick)
• MIG and Flux Cored arc performance
Simple operation. Operator-friendly
control panel is simplified with colorcoded terminals to get you connected
quickly and correctly.
An Eco-nomical and Eco-friendly
alternative. Designed to be up to
25% more fuel-efficient during
typical welding operations than other
models. Output of the engine matches
the power required, saving operating
cost and the environment. The fuel
savings really add up when running
day-after-day, while producing fewer
carbon emissions. Meets tough EPA
Tier 4i compliance standards.
Meter maintenance displays
• Fuel gauge
• Hour meter function
• Oil change interval
• High coolant temperature and low oil
pressure shutdowns
• Low fuel shutdown — engine shuts
down before system runs out of fuel,
making restarts easy.
Compact package. The Big Blue 400
Eco Pro is up to 44% smaller and
41% lighter than other models —
taking less room and reducing
transportation costs.
Quiet operation. In economy mode with
71.5 dBa at 23 ft (7 m), it’s quieter than
most competitive models, improving
work site communication and safety.
Thermal overload protection prevents
machine damage if the duty cycle is
exceeded or airflow is blocked.
See page 3 for more machine features/benefits.
High efficiency. 3-phase, rotating-field
welding generator requires less fuel and
horsepower to operate.
The Vault — ultimate control
board reliability. See page 4.
Welder/generator is warranted by Miller for 3 years, parts and labor.
Engine is warranted separately by engine manufacturer.
