The Power of Blue.
Rugged controls with no printed
circuit boards.
The F3L2011, 3-cylinder Deutz diesel
engineprovides 30 HP at 1850 RPM.
Single side service. Direct fuel injection
for fuel economy and easy starts. Air/oil
double-cooled diesel for maximum
reliability in all environments.
Remote control facility allows
precise adjustment of amperage
without walking back to the machine.
3 kW/kVA auxiliary power while
welding is available from one
120 VAC duplex receptacle and one
240 VAC duplex receptacle that are
circuit breaker protected.
Five welding ranges provide
overlapping ranges and fine current
control in each range for easy set-up
and control of welding amperage.
Compact and lightweight, this low-
speed diesel measures in at 625 x
927 x 1422 mm (24-5/8 x 36-1/2 x
56 in).
3-phase, 4-pole revolving field
technology provides efficient welding
current with less horsepower than DC
generator technology—less horsepower
per welding amp saves fuel—as much
as 20 to 30 percent. Easily connects in
parallel with no special kits for heavy
gouging or stud welding applications.
Note: Parts and labor warranted for three years.
Engine warranted by Deutz for three years.

What Makes Miller Industrial Engine Drives So
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.

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.

Big Blue® 500 X and

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.
“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.”
