Ingersoll Rand Rotary Screw
Air Compressor
This industrial-grade compressor, has a life
expectancy of 30,000 hours, is belt driven and
utilizes an electric clutch control to allow the
compressor to be turned off if not needed.
This design increases efficiency, reduces
fuel consumption and saves you money
at the pump. An automatic belt tensioner
provides proper belt tension even after years
of service. The compressor is protected by
a high-temperature shutdown switch.

Brushes
100 percent
copper-wound
generator
features quick
and easy brush and slip ring inspection.
Brushes can be removed and/or replaced
in a matter of seconds.
The Vault
Superior Circuit Board Design
Our critical circuit boards are engineered
to carry
low power and low heat to reduce
thermal stress and minimize expansion and
contraction. In contrast, our competitor’s
boards carry
high power and high heat,
making them more vulnerable to failure.

CC/CV Units Worry-Free
Concerns with circuit board reliability have
resulted in some operators steering clear of
CC/CV welder/generators — even though they
offer a superior arc and multiple welding
processes. Miller circuit board reliability isn’t
a concern since all Big Blue multiprocess
industrial engine drives feature the Vault.
Created out of two aluminum halves sealed
with silicone, as well as watertight harness
connections, the Vault provides a clean circuit
board environment, protecting the electronics
— and controlling output — in heavy industrial
applications. No other competitor protects their
electronics with a sealed vault, leaving critical
circuit boards exposed to harsh elements that
can disrupt the machine’s electronics, and
therefore, its operation.
