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.

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.

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.

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.
