industry standard for quality and
value. Multiprocess weld output,
strong generator power, and most
important — rated #1 in reliability,
make the Bobcat the welding
industry’s most popular choice.
More horsepower — 23 HP gas/
®
25 HP LP Kohler provides more
power for demanding weld and
generator loads.
Accu-Rated™ 11,000 watts (peak),
480 V, 3-phase power for running
pivot irrigation systems, or
emergency backup power for
milking pumps and other motors.
Heavy-duty construction! Engine,
generator barrel, electrical switches
and other components are protected
against accidental impact.
Accu-Rated™ 10,500 watts (peak),
120/240 V, 1-phase output provides
plenty of power to run power tools,
lights or emergency backup power
for your barn or home.
Exclusive! High-Impact Protective
Armor
• Protective armor with receptacle
and output stud covers provides
a virtually indestructible barrier
from damage
• High-impact resistance in all
temperatures
Other applications include:
automotive bumpers, tractor hoods
and panels, lawn mower decks,
large structural parts, etc.
Patented 12-gallon “smart” fuel tank has a
reservoir design that minimizes the chance of
fuel backflow. Large capacity means more
running time before refueling. Fuel sight
gauges are on both sides.
Output stud and receptacle covers required by OSHA
and CSA for job site safety.
Ten-degree skewed-rotor design boasts better generator
performance. See page 3 for more information.
Fastex™ tool-free oil drain
system combined with hour
meter makes service a snap.
Total Parts Coverage Welder/generator and engine are
warranted for 3 years, parts and labor. Engine is warranted
separately by the engine manufacturer.

The Bobcat Generator Power Advantage
TYPICAL EQUIPMENT POWER USAGE
™
Bobcat 3 Phase will easily start and run the following equipment:
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, Millermatics 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.

To select a generator that has enough power output in watts, add the watts
for the items you want to simultaneously run. Tools and appliances with
induction motors may require 3–7 times the listed wattage when starting.
All data listed is approximate—check your tool/appliance for specific
wattage requirements.

Power
3750 RPM
Tools and motors are designed to operate within 10% of
120/240/480 VAC. The Bobcat’s power generator provides strong
power while keeping the voltage within 10% of 120/240/480 VAC.
This increases tool/motor performance and life.

Fuel Consumption Data
• 12-gallon fuel capacity.
• On a typical job using 1/8-in 7018 electrodes (125 amps, 20% duty cycle)
expect about 20 hours of operation.
• Welding at 150 amps at 40% duty cycle uses approximately 3/4 gallon
per hour— about 16 hours of operation.
• Under a continuous load of 4000 watts of generator power, the Bobcat
would run for about 14 hours.
