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.

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.

Output stud and receptacle covers required by OSHA
and CSA for job site safety.

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 auto matically 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 field­proven durability. Dust cover protects
switches from dirt and grit. Compare to
light-duty switches with smaller 6–10
gauge leads on competitive machines.
