Features

IMPROVED! Quieter and Better Sound

Significant improvements in sound level and quality offer better jobsite communication, which provides a safer, more efficient working environment for you and your crew. New Bobcat welder/generators have rotated the engine toward the front to create more efficient airflow, resulting in significantly quieter 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.

IMPROVED! Smaller and Lighter Design

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

Electronic Fuel Injection (EFI) Option

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 will give you:

27% Better Fuel Economy — Save up to $1,000 per year in fuel
Extended Runtimes — As much as 27% longer
Fast, Easy Starts in All Climates — No choke required
Reliable Operation, Even with Infrequent Use — Less prone to fuel deterioration
More Generator Power: 12,000 watts
Reduced Emissions — 27% less CO and 33% less HC+NOx levels

IMPROVED! Easier Maintenance

With its intuitive design, the daily maintenance of our new Bobcat welder/generators is faster and easier. Front panel maintenance displays let 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 generator 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 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. Use your peak power, it’s more than a number.

Designed for Reliability

From Appleton, Wisconsin, our welder/generators 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 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, which bolts to the machine’s base for greater durability
Long runtimes provide many hours of use before refueling is necessary

Reversed Generator Airflow

Exclusive engine and generator 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.
