Miller Electric Engine-Driven Welder/ AC Generator/Air Compressor User Manual
Big blue, Air pak, The power of blue

Quick
Specs
Quiet at only 70 decibels (95 Lwa)
at idle and 79 decibels (104 Lwa) at
maximum output. Improves jobsite
communications.
Meter maintenance displays
• Fuel gauge
• Hour meter function
• Oil change interval
• High coolant temperature and
low oil pressure shutdowns
• Low fuel shutdown — engine shuts
down before system runs out of
fuel, making restarts easy.
Low maintenance with easy single-side
access to engine and 500 hour oil changes
for both engine and compressor.
Arc-Drive
™
makes welding easy.
Automatically enhances Stick
welding, especially on pipe, by
focusing the arc and preventing
the electrode from going out.
Optional AC/DC/battery charge/
jump-start for AC TIG welding
and 12- or 24-volt batteries. Simply
select the battery voltage and
connect cables to the separate
battery output studs.
(High-frequency unit required for
AC TIG.)

Diesel Engine-Driven Welder/
AC Generator/Air Compressor
Issued June 2012 • Index No. ED/10.5
Hot Start
™
provides positive stick
electrode starts to make it easy to
start all types of electrodes.
Enclosed robust case design protects
internal components from impact and
allows air flow to cool and prolong the life
of the engine. Also reduces sound levels.
Welder/generator/air compressor.
One machine that will do it all. Designed
and built to be the most reliable high-
output system in the world.
Weatherproof Lexan
®
nameplate
resists cracking and fading, and is
color-coded for ease of operation.
GFCI receptacle as required on most
jobsites to protect operators from
electrical hazards.
Heavy-duty low-speed
industrial turbocharged
diesel engine provides
ample power at high altitudes.
Independent compressor controls.
On/off switch for applications not
requiring compressed air. At idle
speed will produce 100 PSI at 40 CFM.
Ultra-reliable industrial rotary screw
air compressor. Belt-driven with
automatic belt tensioner with a life
expectancy of 30,000 hours.
