Miller Electric Engine-Driven Welder/AC Generator - Manual (Page 3)

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 approxi mately 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.
