DC AMPS

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.

Toolless

Generator

Brushes

100% 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

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.
