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 37 times the listed wattage when starting. All data listed
is approximatecheck 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 (12,000 with EFI) 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,

MIG welders 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.

The Bobcat
Competitive
Advantage
The fully enclosed case design virtually eliminates hot air
recirculation when machine is mounted in tight spots.
Louver-directed air flow keeps the temperature of internal parts
cool for maximum performance and extended life.
Self-cooling stator barrel
completely encloses and protects
its generator from the dirtiest
and harshest environments.
