Quiet at only 70 dB (95 Lwa) when idle,
79 dB (104 Lwa) at maximum output.
Improves work site communications.

NEW! Meter maintenance display
• Hour meter function
• Oil Change interval
• Diesel: High coolant temperature

and low oil pressure shutdowns

• Diesel: 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/
for AC TIG welding
and 12 or 24 volt batteries. Simply
select the battery voltage and
connect cables to the separate
battery output studs.

Air Pak

Engine-Driven Welder/

AC Generator/Air Compressor

Issued April 2008 • 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



resists cracking and fading, and is
color-coded for ease of operation.

GFCI receptacle as required on most job sites
to protect operators from electrical hazards.

turbocharged four-cylinder diesel

engine provides ample power at high altitudes.

Independent compressor controls.
On/off switch for applications not
requiring compressed air. At idle
will produce 100 PSI at 40 CFM.


industrial rotary screw air compressor.
Belt-driven with automatic belt tensioner
with a life expectancy of 30,000 hrs.
