  • The Bobcat engine and driven welder/generators have been the top selling in their class because they are engineered to be reliable, powerful and durable from the start.
  • Quieter and better sound. Gas models deliver significant improvements in sound level and quality for better jobsite communication and a safer, more efficient working environment, By rotating the engine toward the front we created a more efficient airflow, resulting in significantly quieter operation, You can start jobs earlier, end later, and work around noise sensitive 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.
  • Easier maintenance - Easy-to-read front panel maintenance displays show when your equipment needs to be serviced, With the intuitive design, the daily maintenance is fast and easy.
  • Oil checks from the top by the front panel.
  • Toolless panels that allow for quick access.
  • Single side fuel fill and oil drain/filter.
  • Optional Electronic Fuel Injection (EFI) - Available on the Bobcat 250 gas model only, Use up to 27 percent less fuel, saving money and improving your bottom line.
  • Smooth power. Better power means better performance. Our Bobcat welder/generators have smoother power — not the spiked power found with other brands — because of: Revolutionary ten-degree skewed-rotor design. Optimized generator performance.
  • Accu-Rated - not inflated generator power - Our Accu-Rated peak power is usable for maximum generator loads, including plasma cutters, wire welders and motor starting, It also beats the competition's very short - duration peak or surge power, Accu-Rated power delivers 11,000 watts (12,000 on Bobcat 250 with EFI) of usable peak power. Peak power delivered for a minimum of 30 seconds.
  • Large 12 gallon fuel capacity means many hours of run time before refueling.
  • Versatile AC and DC weld output provides quality welds on all types of metals, DC is smooth and easy to run while AC Stick is used when arc blow occurs.
  • Maintenance displays show engine hours and hours left before an oil change is due.
  • Heavy-duty construction - All internal components are designed to handle the harshest environments and will run better and last longer.
  • Processes - AC/DC Stick (SMAW), MIG (GMAW)¹, Flux-Cored (FCAW)¹, AC²/DC TIG (GTAW), Air Carbon Arc Cutting and Gouging (CAC-A)³ (rated 3/16". carbons), With voltage-sensing feeder only, With Dynasty 200 Series or HF-251 (non-critical), Bobcat 250 models only.
  • EFI GAS ENGINE Electronic fuel injection (EFI) gas engines optimize the air/fuel ratio for all engine speeds and engine loads, resulting in lower operational costs, fewer emissions, longer runtimes and better performance when compared to carbureted models. The payback from fuel savings alone is a matter of months.
  • Efi advantages (vs. carburetor models) - 12,000 watts of generator power, Up to 27% better fuel efficiency, Extended runtimes up to 27%, Fast, easy starts in all climates, Reliable operation, even with infrequent use, Fewer emissions — 27% less CO and 33% lower HC+NOx levels.
  • Rugged multipurpose engine drives are ideal for mobile maintenance trucks where reduced size and weight are essential, They are great for Stick and Flux - Cored welding, Carbon Arc gouging, and are designed to handle maintenance/ repair, construction, farm/ranch, and generator use.
  • Front panel fuel gauge provides convenient fuel level indication.
  • Smoother weld output and better generator power while welding.
  • More weld output than
