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.

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.

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.

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.
