RECOMMENDED APPLICATIONS

OPERATIONAL FEATURES AND CONTROLS

The POWER ARC 5000 was designed for simplicity.

Therefore, it has very few operating controls. A single

dial on the control panel lets you select either genera-

tor or welding use. For welding, the same dial selects

continuous current output over the machine’s 70 to

125 amp low range and 90 to 150 amp high range.

The 11 HP Briggs & Stratton gasoline engine controls

include a recoil starter, choke, stop switch and low idle

control. See ENGINE OPERATION Section for

details about starting, running, stopping and breaking

in the gasoline engine.

GENERATOR

The POWER ARC 5000 gives AC generator output for

medium use, commercial demands. For more details

on operating the generator, see GENERATOR OPER-

ATION in this section of the manual.

WELDER

The POWER ARC 5000 provides excellent constant

current AC welding output for stick (SMAW) welding.

For more details on using the machine as a welder,

see WELDING OPERATION in this section of the

manual.

WELDING CAPABILITY

The POWER ARC 5000 is rated 150 amps, 25 volts at

40% duty cycle on a ten-minute basis. This means

that you can load the welder to 150 amps for four

minutes out of every ten-minute period. The machine

is also capable of higher duty cycles at lower output

currents. You can load the welder to 125 amps for six

minutes out of ten for a 60% duty cycle.

The current is continuously variable from 70 to 125

amps and 90 to 150 amps depending on which out-

put range is selected. The POWER ARC 5000 can

weld with all 3/32”, most 1/8”, and some 5/32” diam-

eter Lincoln AC electrodes.

LIMITATIONS

• The POWER ARC 5000 is not recommended for

any processes besides those that are normally per-

formed using stick welding (SMAW) procedures.

• The POWER ARC 5000 is not recommended for

pipe thawing.

• The POWER ARC 5000 is not

recommended for

AC TIG welding.

• 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.
