DIf the engine is warm, checking is needed, and there is no overflow tank, follow the next two statements.

DWear safety glasses and gloves and put a rag over radiator cap.

DTurn cap slightly and let pressure escape slowly before completely re- moving cap.

ENGINE EXHAUST GASES can kill.

D Use equipment outside in open, well-ventilated ar- eas.

DIf used in a closed area, vent engine exhaust outside

and away from any building air intakes.

BATTERY ACID can BURN SKIN and EYES.

DDo not tip battery.

DReplace damaged battery.

DFlush eyes and skin immediately with water.

ENGINE HEAT can cause fire.

DDo not locate unit on, over, or near combustible surfaces or flammables.

DKeep exhaust and exhaust pipes way from flam- mables.

EXHAUST SPARKS can cause fire.

DDo not let engine exhaust sparks cause fire.

DUse approved engine exhaust spark arrestor in re- quired areas — see applicable codes.

1-4. Compressed Air Hazards

BREATHING COMPRESSED AIR can cause serious injury or death.

DDo not use compressed air for breathing.

DUse only for cutting, gouging, and tools.

HOT METAL from air arc cutting and gouging can cause fire or explosion.

DDo not cut or gouge near flammables.

DWatch for fire; keep extinguisher nearby.

COMPRESSED AIR can cause injury.

DWear approved safety goggles.

DDo not direct air stream toward self or others.

TRAPPED AIR PRESSURE AND WHIPPING HOSES can cause injury.

DRelease air pressure from tools and system before servicing, adding or changing attachments, or open- ing compressor oil drain or oil fill cap.

HOT PARTS can cause burns and injury.

DDo not touch hot compressor or air system parts.

DLet system cool down before touching or servicing.

READ INSTRUCTIONS.

DRead Owner’s Manual before using or servicing unit.

DStop engine and release air pressure before servicing.

1-5. Additional Symbols For Installation, Operation, And Maintenance

FALLING UNIT can cause injury.

DUse lifting eye to lift unit only, NOT running gear, gas cylinders, trailer, or any other accessories.

DUse equipment of adequate capacity to lift and support unit.

DIf using lift forks to move unit, be sure forks are long enough to extend beyond opposite side of unit.

OVERUSE can cause OVERHEATING.

DAllow cooling period; follow rated duty cycle.

DReduce current or reduce duty cycle before starting to weld again.

DDo not block or filter airflow to unit.

OVERHEATING can damage motors.

DTurn off or unplug equipment before starting or stop- ping engine.

DDo not let low voltage and frequency caused by low engine speed damage electric motors.

DDo not connect 50 or 60 Hertz motors to the 100 Hertz receptacle where applicable.

STATIC (ESD) can damage PC boards.

DPut on grounded wrist strap BEFORE handling boards or parts.

DUse proper static-proof bags and boxes to store, move, or ship PC boards.

FLYING SPARKS can cause injury.

D Wear a face shield to protect eyes and face.

D Shape tungsten electrode only on grinder with proper guards in a safe location wearing proper face, hand, and body protection.

DSparks can cause fires — keep flammables away.

Big Blue 602P, Big Blue 502P, Big Blue 402P specifications

Miller Electric is a well-respected name in the welding industry, known for its high-quality portable welders that cater to a wide range of applications. Among their iconic products are the Big Blue 502P, Big Blue 402P, and Big Blue 602P, each offering unique features and capabilities suited to professional welders.

The Miller Big Blue 502P is recognized for its robust construction and high-performance capabilities. Powered by a reliable diesel engine, it provides 500 amps of welding power at a duty cycle of 100%. This model is particularly favored for its versatility, accommodating both stick and TIG welding processes. One of its key technologies is the Auto-Set feature, which automatically adjusts settings for optimal performance based on the material thickness. This welder also boasts a user-friendly interface, complete with easy-to-read digital displays for monitoring essential parameters.

In contrast, the Big Blue 402P offers a slightly lower welding output while maintaining many of the advanced features seen in its larger counterpart. With a maximum output of 400 amps, it is perfectly suited for light to medium-duty applications. The 402P is particularly lightweight for a diesel welder, making it an ideal choice for contractors who need mobility without sacrificing power. It includes the X-Mode technology, which ensures reliable performance in challenging conditions and offers an intuitive control panel for ease of use.

The Big Blue 602P, on the other hand, stands out for its high output and exceptional reliability. With a maximum capacity of 600 amps, this machine is designed for heavy-duty applications, making it perfect for industrial settings. The welder features advanced cooling systems and robust construction, which enhance durability and longevity. One notable characteristic of the 602P is its ability to handle various welding processes, including Stick, TIG, and MIG, making it a versatile tool for skilled welders. Additionally, the Big Blue 602P incorporates advanced inverter technology, resulting in a lighter and more energy-efficient model without compromising power performance.

All three models benefit from Miller's commitment to innovation and user-centric design features. Built to thrive in tough work environments, the Big Blue series is equipped with protective casings and vibration-resistant components. Safety is also a priority, with several built-in features that help protect users during operation.

In summary, the Miller Electric Big Blue 502P, 402P, and 602P each bring unique strengths to the welding market. Their notable features include advanced technologies, robust construction, and versatile applications, ensuring that professionals have the right tool for any welding job. Whether for light-duty tasks or heavy industrial applications, Miller Electric's Big Blue series remains a cornerstone for welders around the globe.
