Trailblazer®325 Diesel

Diesel Engine-Driven

Welder/AC Generator

Issued July 2018 • Index No. ED/4.8

Welder/generator is warranted for three years, parts and labor.

Engine is warranted separately by the engine manufacturer.

Trailblazer 325 Diesel with optional
ArcReach and Excel power shown.

The Trailblazer exclusive
technologies — Auto-Speed

™

and optional Excel™power —
deliver superior runtimes, increased
fuel efficiency, and improved
welder/generator performance.

No other compact machine in
the 300-amp class delivers more
welding power or more auxiliary
power with better fuel efficiency
and less noise — for productive,
profitable, quieter jobsites.

Remote control of the power source
without a cord.

Trailblazer®Technologies

Excel™power (option)

Power at idle — a Miller exclusive. Unlike competitive machines that
provide auxiliary power only at 3,600 rpm (max), Excel power delivers a
full 2,400 watts (20 A) of 120-volt inverter-based, pure sine wave power
at 2,400 rpm while not welding. With Excel power you can operate jobsite
tools like grinders at quiet, fuel-saving speeds.

Refueling time and operating costs are reduced with Excel power, which
means more productivity and profitability. Plus everyone on the jobsite
gets a better working environment because noise levels and exhaust
emissions are lowered. Excel power — available only from Miller.

Dynamic DIG

™

Ultra-adaptive arc control. Unlike conventional DIG
that provides a preset amount of short-clearing
current, Miller’s proprietary Dynamic DIG works on
a time-based algorithm that automatically adjusts

the amount of current required to clear a short. What does this mean?
A smoother more consistent arc that can be tailored to match application,
material, fit-up, and welder technique.

Based on generator-only use for total runtime.

Auto-Speed™technology

Matches engine speed to load — a Miller exclusive. Get the welding
power you need — plus reduced fuel consumption and lower noise
levels for a more-profitable, safer jobsite.

Unlike competitive machines that operate at 3,600 rpm (max) under
any load, Miller-exclusive Auto-Speed technology responds to weld
requirements by automatically adjusting engine speed to one of five rpm
levels so the engine never works harder than necessary. Weld up to 135 amps
while the engine remains at idle (1,800 rpm), saving up to 15 percent
in fuel over competitive units, and drastically reducing jobsite noise.

Unbeatable arc performance

Wide amperage output with better welding deposition rates means you
can get jobs done faster, saving time and money. The Trailblazer also has
precise arc control, which allows you to fine-tune the arc to match your

personal preferences and quickly dial in the perfect parameters to
optimize weld quality and maximize productivity across a variety of
applications and welding processes.

ArcReach®remote control technology (option)

Remote control of the power source
without a control cord. An ArcReach

system allows you to change weld
settings from your ArcReach feeder or remote, saving a trip to the
power supply. ArcReach technology uses the existing weld cable to
communicate welding control information between the feeder or remote
and the power source. This technology eliminates the need for control
cords, and their associated problems and costs.

Safer, more productive jobsites

Quieter jobsites are safer and more productive because work crews can
communicate easier, and work can start earlier and end later — even in
noise-sensitive areas. Miller-exclusive Auto-Speed technology makes this
welder/generator the quietest Trailblazer diesel yet — rated at 70 db at
idle (1,800 rpm). If your jobsite needs a welder/generator, it needs a
Trailblazer welder/generator — because no other diesel-fueled choice in
this category is as quiet.

Optional ArcReach®remote control technology eliminates the need to
trace or move heavy secondary weld leads bundled with control cords
on the jobsite. Complete remote control of welding processes and
parameters improves safety by limiting jobsite movement and reducing
slip, trip and fall hazards.

More portable, uses less truck and jobsite space

Trailblazer welder/generators are up to 24 percent smaller and
10 percent lighter then competitive machines — which means moving
them is faster and easier, for maximum productivity. And because
they take up less space, Trailblazer welder/generators let work trucks
carry more equipment and gear — so your work crews can be ready
for anything.

Cleaner and stronger generator power

Combined with a 25-horsepower engine, Trailblazer welder/generators
offer 12,000 watts of clean, truly usable generator power that is
Accu-Rated™, not inflated: tested to deliver uninterrupted peak output for
a minimum of 30 seconds for big loads, so you can get more jobs done.

An independent welder and generator power system ensures no
interaction between jobsite tools and the welding arc, while advanced
generator technology virtually eliminates power spikes and other electrical
imperfections — so welds are cleaner and jobsite tools can run without
interruption, maximizing quality, productivity and profit.

Fewer refueling trips

No other diesel welder/generator in the 300-amp class lets your crews
spend more time working and less time refueling — because only
Trailblazer welder/generators provide Auto-Speed™technology, plus the
Excel™power option, to deliver maximum runtime.

Maximum cost savings

Less money spent on fuel means more profit for you. Every Trailblazer
welder/generator has fuel-saving Auto-Speed technology; add optional
Excel power to save even more on fuel costs and enjoy a combination of
advanced, profit-enhancing features that are only available on a Trailblazer
welder/generator.
