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.
Bobcats will easily start and run the following equipment:
For example, if you’re welding at 125 amps you also have 5200 watts
available for powering lights or tools (either 43 amps from the 120 volt
full kVA receptacle or 21 amps from the 240 volt full kVA receptacle).
*50 A, 120/240 VAC receptacle. See Owner’s Manual for additional information.

The Bobcat Generator Power Advantage
Tools and motors are designed to operate within 10% of 120/240 VAC. The
Bobcat’s power generator provides strong power while keeping the voltage
within 10% of 120/240 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 A, 20% duty cycle) expect about
20 hrs (gas) or 24 hrs (diesel) of operation.
• Welding at 150 A, 40% duty cycle uses approxi mately:
3/4 gallon per hour — about 16 hrs of operation (gas) or
1/2 gallon per hour — about 20 hrs of operation (diesel).
• Under a continuous load of 4000 watts of generator power, the Bobcat would run for
about 14 hrs (gas) or about 17 hrs of operation (diesel).
