Miller Bobcat 250 Application Guide

Welder/AC Generator:
Best Value For Power Needs
While you might not need a generator or welder for daily use,
investing in a machine that performs both duties makes
economic sense.
Like a “regular” generator, a Miller welder/AC generator provides
120 and 240 volts AC generator power. The 4,500 to 10,000 watt
output capability of Miller’s mid-size generators is also suitable
for home use.
What are the biggest benefits to a Miller welder/AC generator?
 At about the same cost as a “regular” generator, Miller
generators are also excellent welding power sources
capable of welding material up to 1/2 in. thick or more.
 Miller’s 3-year, True Blue
®
Total Parts warranty is longer than
typical 1-year, generator warranties.
 Low Fuel Consumption − The Bobcat will run about 14 hours
under a continuous load of 4000 watts of generator power.
Weld at 150 Amps at 40% duty cycle for 16 hours!
 Accu-Rated™ Miller generators means they deliver the
power that is promised. Patented self-cooling
stator allows Miller generators to perform at
100% duty cycle, even in 104°F heat! And
the Bobcat’s skewed rotor helps provide
smoother power than other brands.
