Lincoln Electric IM972 manual Welding Capability, Limitations

B-3 OPERATION B-3

GENERAL DESCRIPTION

The OUTBACK™ 185 is designed for commercial 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 120 / 240 volt, single-phase AC power. The machine is portable.

A Kohler CS 12.75 HP air cooled, OHV gasoline engine powers the welder / generator. It has an engine warranty of 3 years.

RECOMMENDED APPLICATIONS

Welder

The OUTBACK™ 185 provides excellent constant current DC welding output for stick (SMAW) welding.

Generator

The OUTBACK™ 185 gives smooth AC generator output for continuous auxiliary power usage within the engine manufacturerʼs required maintenance recom- mendations.

OPERATIONAL FEATURES AND CONTROLS

The OUTBACK™ 185 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 machineʼs 50 to 185 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

•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

120 / 240 volt single phase AC auxiliary power.

•Kohler CS 12.75 HP overhead cam air-cooled gasoline engine. Smooth running, long life.

WELDING CAPABILITY

The OUTBACK™ 185 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 120 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 can, therefore, weld with all 3/32”, 1/8” and most 5/32” diameter Lincoln DC electrodes.

LIMITATIONS

•The OUTBACK™ 185 is not recommended for any processes besides those that are normally per- formed using stick welding (SMAW) procedures.

•The OUTBACK™ 185 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 EQUIPMENT WHILE YOU ARE WELDING.
