Fastex™tool-free oil drain

system combined with hour

meter makes service a snap.

Heavy-duty construction! Engine,

generator barrel, electrical switches

and other components are protected

against accidental impact.

More horsepower — 23 HP gas/

25 HP LP Kohler®provides more

power for demanding weld and

generator loads.

Reliable Bobcat engine-driven

welding generators are the

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.

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.

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.

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.

The Power of Blue®

Total Parts Coverage Welder/generator and engine are

warranted for 3 years, parts and labor. Engine is warranted

separately by the engine manufacturer.

Function Guide

1. Engine Hour Meter is convenient for monitoring maintenance intervals.

2. Weld Process Selector Switch makes choosing between Stick, Wire

and TIG processes easy. Switch also automatically changes polarity

with process selection to make sure the machine is set up properly to

weld with little effort or knowledge.

3. Coarse Range Control. Three Stick/TIG and one Wire range are

available for output control. Stick/TIG ranges are designed to electrode

diameters (3/32", 1/8", 5/32") making these models very easy to set.

4. Fine Adjust Control makes it easy to fine tune amperage within a

coarse range. Set control above 7 for best power while welding and to

10 for generator-only use.

5. Engine Control Switch is used to start the engine and then select

between Auto Idle and High Speed Lock.

6. Engine Choke Control is used for easy engine starting.

7. 120 VAC and 240 VAC* Covered Receptacles with Circuit Breakers

meet/exceed OSHA/CSA requirements for job site safety (optional

120 VAC GFCI receptacles available).

*For matching plug, order #119 172.

8. 480 VAC* Covered Receptacle with Circuit Breaker meet/exceed

OSHA/CSA requirements for job site safety.

*For matching plug, order #165 963.

Make deadlines, not excuses.

• 68% of service technicians, managers

and owners, recommend the Bobcat

over the competition.

• 98% of current owners are “satisfied

to very satisfied” with the Bobcat*.

*Based on an independent survey of

thousands of Bobcat owners.

The Bobcat

Competitive

Advantage

Rated #1 in Reliability

Large 3–4 gauge leads are lugged to

heavy-duty range switches for field-

proven durability. Dust cover protects

switches from dirt and grit. Compare to

light-duty switches with smaller 6–10

gauge leads on competitive machines.

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.

Bobcat 3 Phase will easily start and run the following equipment:

The Bobcat Generator Power Advantage

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.

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.

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.

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.
