OUTBACK™ 145
¤
GENERAL DESCRIPTION
The OUTBACK™ 145 is designed for commercial use
welder/generator applications. As a welder it provides
145 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 145 amps.
As a generator it can supply up to surge watts or
continuous watts of 120 / 240 volt, single-phase AC
power. The machine is portable.
A Subaru Robin EX30 10 HP air cooled, OHC gaso-
line engine powers the welder / generator. It has an
engine warranty of 3 years.
RECOMMENDED APPLICATIONS
Welder
The OUTBACK™ 145 provides excellent constant
current DC welding output for stick (SMAW) welding.
Generator
The OUTBACK™ 145 gives smooth AC generator
output for continuous auxiliary power usage within the
engine manufacturer’s required maintenance recom-
mendations.
OPERATIONAL FEATURES AND
CONTROLS
The OUTBACK™ 145 was designed for simplicity.
Therefore, it has very few operating controls. A single
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
145 amp range.
The gasoline 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
gasoline engine.
DESIGN FEATURES AND
ADVANTAGES
• 145 amp DC constant current welding for stick
electrodes.
• Lightweight / portable.
• Full range, continuous welding output control with
a single knob.
• Hour Meter Standard.
• Surge watts or Watts of continuous 120 / 240 volt
single phase AC auxiliary power.
• Subaru Robin EX30 overhead cam air-cooled
gasoline engine. Smooth running, long life.
WELDING CAPABILITY
The OUTBACK™ 145 is rated at 100 amps, 25VDC at
60% duty cycle on a ten-minute basis. This means
that you can load the welder to 100 amps for six-min-
utes out of every ten-minute period. The machine is
capable of higher duty cycles at lower output cur-
rents.
The current is continuously variable from 50 to 145
amps DC. The OUTBACK™ 145 can, therefore, weld
with 3/32”, 1/8” and some 5/32” diameter Lincoln DC
electrodes.
LIMITATIONS
• The OUTBACK™ 145 is not recommended for
any processes besides those that are normally
performed using stick welding (SMAW) proce-
dures.
• The OUTBACK™ 145 is not recommended for
pipe thawing.
• During welding, generator power is limited to 100
watts, and output voltages can drop from 120 to
80 volts and 240 to 160 volts. Therefore, DO NOT
OPERATE ANY SENSITIVE ELECTRICAL EQUIP-
MENT WHILE YOU ARE WELDING.
