Rigorous Testing for Tough,
Real-World Conditions
To prove our machines go to the
limit, Miller industrial engine
drives are put to the test in very
extreme environmental conditions.
• Airborne Dust and Sand —
Critical components are
exposed to abusive airborne
particles in a special testing
chamber for weeks, helping
make sure they’ll operate while
facing extreme levels of dirt,
dust or sand on the job site.
• Humidity and Corrosion —
Inside Miller’s Houston testing
room, critical components are
subjected to extended
moisture and corrosive salt
exposure to ensure they’ll run even when exposed to humid
climates, corrosive coastal environments, and driving rain.
• Temperature Extremes — Miller’s industrial engine drives
are tested to ensure performance in scorching heat. All Miller
engine driven machines are weld rated at 104˚ F, but actual
tests are conducted up to 122˚ F to assure peak performance.
• Jobsite/Over-the-Road Abuse — Miller industrial engine
drives are shaken for hours on transportation bed simulators,
subjected to severe vibration, and test-dropped and jerked to
ensure they’ll withstand the stresses that can shut down
competitive machines.
• Continuous Operation — Miller’s industrial engine drives run
day and night, in all weather conditions, to assure they’ll perform
without interruption in the field.
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.
What Makes Miller Industrial Engine Drives So ?
“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.
“The PRO 300 worked year ’round and never caused any
problems. We were amazed at the cold-weather starting. A
machine that doesn’t run means we have to work overtime…
secondly, you don’t want to have a crew standing around at
$200 an hour while someone tries to start the machine.”
Edward McNaughton, Nordcap Steel Docks
