OVERVIEW

Industrial Power and Precision on the Go

The Miller Bobcat 3-Phase Engine-Driven Welder (907505) is a powerhouse solution designed for professionals who require versatile power generation alongside superior welding performance. Unlike standard engine drives, this unit is engineered to provide 3-Phase power, making it an indispensable asset for running industrial motors, pumps, and heavy-duty tools in the field. With 11,000 watts of Accu-Rated™ peak power, it ensures that your auxiliary equipment receives consistent, usable energy for at least 30 seconds—perfect for starting motors or running plasma cutters without the voltage drops associated with lesser machines.

Engineered for Reliability and Durability

Built in Appleton, Wisconsin, the Bobcat series is synonymous with toughness. This machine features copper windings and iron generator components, ensuring longevity even under extreme working conditions. The internal leads are lugged, not soldered, providing superior field durability against vibration and thermal cycling. To protect your investment, the unit is encased in super-tough armor with protective doors covering weld studs and receptacles, meeting OSHA and CSA requirements for jobsite safety. The integrated lift hook bolts directly to the frame, ensuring safe and secure lifting when moving the unit between sites.

Advanced Airflow and Maintenance

Miller has revolutionized the cooling system with a reversed auxiliary power unit airflow design. By rotating the engine towards the front, airflow is optimized to keep internal parts cool and reduce sound levels. This design eliminates hot air recirculation when the machine is mounted in tight spots, such as truck corners. Maintenance is streamlined with intuitive front panel displays that indicate service intervals. Oil checks can be performed from the top, and toolless panels allow for quick access to the single-side fuel fill and oil drain, minimizing downtime and keeping your operation running smoothly.

FAQ

The primary difference is its ability to generate 3-Phase electrical power, which is required for operating certain industrial motors and heavy-duty equipment, in addition to standard single-phase power.

Yes, this specific model (907505) comes equipped with GFCI (Ground Fault Circuit Interrupter) receptacles for enhanced electrical safety on the jobsite.

The machine provides 11,000 watts of Accu-Rated™ peak power, designed to deliver usable peak power for a minimum of 30 seconds for starting motors and high-draw loads.

Yes, the Bobcat features a design where the engine is rotated forward for efficient airflow, resulting in significantly quieter operation suitable for work near homes, hospitals, and businesses.

Absolutely. The Bobcat provides smooth power excellent for MIG welding when paired with a compatible wire feeder, such as a Millermatic or a voltage-sensing feeder.

Maintenance is very user-friendly with front panel displays to track service needs, toolless panels for quick access, and single-side fuel fill and oil drain locations.

While some listings may mention leads, standard Miller engine drives typically do not include weld leads in the base crate unless specified as a complete package. Please verify the specific bundle.

This model is powered by a gasoline engine. It is designed for efficiency and long runtimes.
