Electronic Fuel

Injection (EFI) Benefits

vs Carburetor Models

• 12% to 27% better fuel economy!

• Reduced emissions—33% lower

HC+Nox levels and 27% lower CO!

(EPA 1000 Hour Certification)

• Easy starting in all climates with no

choke required

• Elimination of carburetor icing

• Better high-altitude performance

(electric fuel pump is recommended)

• EFI is more reliable when using

equipment infrequently

• 12,000 watts of generator power and

more weld output

Optional Bobcat 250 EFI Model with

12,000 Watts and More Weld Power!

Fuel capacity of 12 gallons means many

hours of run time before refueling.

Meter maintenance displays:

• Hour meter function and oil change interval

• Diesel: High coolant temperature shutdown,

low oil pressure shutdown and low fuel

shutdown—engine shuts down before

system runs out of fuel making restarts easy

Versatile AC and DC Stick/TIG plus Wire

capabilities provide quality welds on all

types of metals. DC is smooth and easy

to run while AC Stick is used when arc

blow occurs.

Note: AC TIG requires Dynasty 200 Series or

HF-251 (non-critical).

Welding and generator power ratings are

at 104˚F (40˚C)—highest in its class to

ensure reliable performance.
