Additional Features
One MIG welding range allows precise voltage
control for welding with .023 –.120 inch
(0.6 – 3.2 mm) wires.
A multi-colored process selector control
allows quick and easy process changes without
having to use multiple switches.
14-pin remote control allows precise adjustment
of amperage or voltage, along with contactor
control, without walking back to the machine.
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.
“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 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.
