Bobcat™ 3 Phase Engine-Driven Welder | MillerWelds

Bobcat™ 3 Phase (Kohler), GFCI

Designed for farm and ranch owners in need of single and three-phase power to run 480 volt three-phase pivot irrigation systems. Provides additional auxiliary power for the farm and ranch.


Quiet Operation
Significant improvements in sound level and quality offer better jobsite communication, which provides a safer, more efficient working environment for you and your crew. The engine in Bobcat engine-driven welders is rotated toward the front for efficient airflow and quiet operation. Now you can start your job earlier in the day and end it later, as well as work around hospitals, businesses, and residential areas.
Small, Light Design
Bobcat engine-driven welders take up less space on trucks and trailers — leaving more room on your truck for other equipment and tools. Plus, they’re easy to move around jobsites — even with weld cables and running gear attached.
Easy Maintenance
With its intuitive design, the daily maintenance of Bobcat engine-driven welders is fast and easy. With front panel maintenance displays, you know when your equipment needs to be serviced. And servicing is simple because of: 
  • Oil checks that can be performed from the top by the front panel
  • Toolless panels that allow for quick access
  • Single-side fuel fill and oil drain/filter
Smooth Power – Not Spike Power
Revolutionary ten-degree skewed-rotor design optimizes auxiliary output performance for smoother power — not spiked power found with other brands. Better power — better performance.
Accu-Rated™ — Not Inflated Generator Power
Miller’s Accu-Rated™ 11,000 watts (12,000 with EFI) of usable peak power is delivered for a minimum of 30 seconds. Accu-Rated means peak power is usable for maximum auxiliary power loads such as plasma cutting, Millermatic® MIG welders and motor starting. Accu-Rated peak power beats the competition’s very shortduration peak or surge power. Use your peak power, it’s more than a number.
Designed for Reliability
From Appleton, Wisconsin, our engine-driven welders are the most rugged, durable and long-lasting in the industry. We manufacture them to exceed requirements for extreme working conditions and they are hard-working from the core:
  • Copper windings and iron generator components for a quality-built machine
  • Lugged — not soldered — heavy internal leads for better field durability
  • Superior cooling technology for maximum performance and engine life
  • Super-tough armor to protect the engine-driven welder from accidental impact
  • Protective armor doors to cover the weld studs and receptacles as required by OSHA and CSA for jobsite safety
  • Lift hook integrated into the center frame, which bolts to the machine’s base for greater durability
  • Long runtimes provide many hours of use before refueling is necessary
Reversed Auxiliary Power Unit Airflow
Exclusive engine and auxiliary power unit packaging design operates cooler and more efficiently. The engine is rotated towards the front to create more efficient airflow. More efficient airflow and exclusive engine location are significant contributors to reduced sound level and size reduction. Hot air recirculation is eliminated when machine is mounted in tight spots, and internal parts are kept cool for optimal performance.
