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 can be removed and/or replaced
in a matter of seconds.
The Vault
Superior Circuit Board Design
Miller’s 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.
“The Vault” Makes Upgrading to Miller 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’s circuit board reliability isn’t
a concern since all PRO 300 and 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.
