GENERAL DESCRIPTION
OUTBACK
TM
185 (AU)
The OUTBACK™ 185 (AU) is designed for commer-
cial use welder/generator applications. As a welder it
provides 185 amps of DC constant current for welding
with DC stick electrodes. A single dial lets you select
a full range of welding output from 50 to 185 amps.
As a generator it can supply up to 5700 surge watts or
5200 continuous watts of 240 volt, single-phase AC
power. The machine is portable.
A Kohler CH440 14 HP air cooled, OHV petrol engine
powers the welder / generator. It has an engine war-
ranty of 3 years.
RECOMMENDED APPLICATIONS
Welder
The OUTBACK™ 185 (AU) provides excellent con-
stant current DC welding output for stick (SMAW)
welding.
Generator
The OUTBACK™ 185 (AU) gives smooth AC genera-
tor output for continuous auxiliary power usage within
the engine manufacturer's required maintenance rec-
ommendations.
OPERATIONAL FEATuRES AND
CONTROLS
The OUTBACK™ 185 (AU) was designed for simplici-
ty. Therefore, it has very few operating controls. A sin-
gle dial on the control panel lets you select either
welder or generator use. For welding, the same dial
selects continuous current output over the machine's
50 to 185 amp range.
The petrol engine controls include a recoil starter,
choke and stop switch. See ENGINE OPERATION in
the OPERATION section of this manual for details
about starting, running, stopping, and breaking in the
petrol engine.
DESIGN FEATuRES AND
ADVANTAGES
• 185 amp DC constant current welding for stick
electrodes.
• Lightweight / portable.
• Full range, continuous welding output control with
a single knob.
• Automatic shutdown under low oil level condition.
• Hour Meter Standard.
• 5700 Surge watts or 5200 Watts of continuous
240 volt single phase AC auxiliary power.
• Kohler CH440 14 HP overhead cam air-cooled
petrol engine. Smooth running, long life.
WELDING CAPABILITY
The OUTBACK™ 185 (AU) rated 185 amps, 20 VDC
at 10% duty cycle on a ten-minute basis. This means
that you can load the welder to 185 amps for one
minute out of every ten-minute period. The machine
is capable of higher duty cycles at lower output cur-
rents. For example, you can load the welder to 100
amps for ten minutes out of ten for a 100% duty cycle.
The current is continuously variable from 50 to 185
amps DC. The OUTBACK™ 185 (AU) can, therefore,
weld with all 2.4mm (3/32"), 3.2mm (1/8") and most
4.0mm (5/32") diameter Lincoln DC electrodes.
LIMITATIONS
• The OUTBACK™ 185 (AU) is not recommended
for any processes besides those that are normally
performed using stick welding (SMAW) proce-
dures.
• The OUTBACK™ 185 (AU) is not recommended
for pipe thawing.
• During welding, generator power is limited to 100
watts, and output voltages can drop from 240 to
160 volts. Therefore, DO NOT OPERATE ANY
SENSITIVE ELECTRICAL EQUIPMENT WHILE
YOU ARE WELDING.
