Miller Bobcat 250 (Kohler) with Electric Fuel Pump #907500002

Quieter and Better Sound

Significant improvements in sound level and quality enable better jobsite communication for a safer, more efficient working environment. Bobcat welder/generators have the engine rotated forward for more efficient airflow, resulting in significantly quieter operation. You can start your job earlier in the day and end it later, even around hospitals, businesses, and residential areas.

Smaller and Lighter Design

Bobcat welder/generators take up less space on trucks and trailers—leaving more room for other equipment and tools. Plus, they’re easier to move around jobsites—even with weld cables and running gear attached.

Smooth Power — Not Spike Power

Bobcat's Revolutionary ten-degree skewed-rotor design optimizes generator performance for smoother power — not spiked power found with other brands. Better power, better performance!

Easier Maintenance

With its intuitive design, the maintenance of Bobcat welder/ generators is faster and easier. 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

Designed for Reliability

Bobcat welder/generators are the most rugged, durable and long-lasting in the industry. They're built 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 greater durability
  • Superior cooling technology for maximum performance and engine life
  • Super-tough armor to protect the welder/generator 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 and bolted to the machine’s base for greater durability
  • Long run times provide many hours of use before refueling is necessary

Accu-Rated™ – Not Inflated Generator Power

Miller’s Accu-Rated™ 11,000 watts of usable peak power is delivered for a minimum of 30 seconds. Accu-Rated means peak power is usable for maximum generator loads such as plasma cutting, Millermatic® MIG welders, and motor starting. Accu-Rated peak power beats the competition’s very short duration peak or surge power.

Reversed Generator Airflow

Reversed Generator Airflow engine and generator packaging design operates cooler and more efficiently. The engine is rotated towards the front for more efficient airflow, which results in reduced sound level and size reduction. Hot air recirculation is eliminated when the machine is mounted in tight spots, and internal parts are kept cool for optimal performance.

Product Questions and Answers


Q - What engine is in this? A - Kohler CH730, four-cycle, air-coo9led, gasoline engine.
Q - I need a GFCI receptacle for this. Do you have those? A - Yes, the part number is 300975 and the kit contains 2 GFCI 120 V duplex receptacles.

How to adjust engine speed :

  1. Check engine speeds.

    After starting engine, check engine speeds with a tachometer (see reference table in owner’s manual).

  2. Adjust engine speeds.

    If necessary, adjust speeds as follows: Start engine and run until warm. Turn Fine Control to 10. Remove rear panel and air cleaner to access idle speed adjustments.

  3. Adjust Idle Speed.

    Move Engine Control switch to Run/Idle position. Loosen mounting screw. Adjust solenoid position so engine runs at idle speed. If necessary, back out idle speed screw so solenoid can be moved to correct position. Tighten mounting screw. Be sure solenoid linkage works smoothly. Turn idle speed screw for fine adjustments.
