Every component in a Miller industrial engine drive is engineered and built to assure
ultimate reliability in the most punishing conditions. And they are rigorously tested to
the toughest real-world conditions to keep working in a tough world.
Ultimate Circuit Board Protection
No matter how well it’s built, any machine can fail if its critical circuit boards are
compromised. Miller makes two types of industrial engine drives, both of which ensure
that no critical circuit boards are left vulnerable.
“CC” Stick and TIG Models
— Miller’s robust, efficient constant current (CC) industrial
engine drives for Stick and TIG welding are designed with no circuit boards that are critical
to the machine’s operation. That means no boards can shut down the machine if they fail.
“CC/CV” Multiprocess Models
— Miller’s Multiprocess
PRO 300 and Big Blue
®
models of industrial engine drives
include circuit boards for superior arc control and welding
versatility. These boards are protected by the Vault, a
hermetically-sealed aluminum case that is impenetrable to
dust, salt, and moisture.
Similar models to consider:
Big Blue
®
400 X
See Lit. No. EDX/10.1
For the professional
heavy-duty construction
contractor, pipeline, rental
company or anyone wanting
a fuel-efficient low-speed diesel-powered
multiprocess welder/generator with precise arc
control. The heavy-duty, compact case easily
fits sideways in a standard pickup bed. This
model provides the quietest operation of Miller’s
engine-drive machines.
Big Blue
®
500 X and
600 X
See Lit. No. EDX/10.11
For fleet owners, heavy-duty
construction contractors,
and rental companies who
want a low-speed diesel-
powered welder/generator with rugged reliability
and proven performance. Ideal for really tough
jobs that may be using larger electrodes for Stick
welding or Carbon Arc gouging. Available in either
a Stick/TIG CC only model, or a more versatile
CC/CV multiprocess model. Easy to maintain and
always ready to weld no matter what the job or
conditions demand.
What Makes Miller Industrial Engine Drives So
?
“Other machines would cut out when we gouged too long
with them. With the Miller, I gouged hard all day in 98 degree
heat and never had a shutdown when we were running
3/8-in carbons.” When welding, “The Big Blue starts out
hot, where I want it, and stays steady on its heat all day.”
— Welder Tommy Langley, Fluor Daniel/Chevron Oil Refinery
