GENERATOR OPERATION

CAUTION

Be sure that any electrical equipment plugged into the generator’s AC power receptacles can withstand a ±10% voltage and a ±3% frequency variation. Some electronic devices cannot be powered by the POWER- ARC 4000. Refer to Table A.2, ELECTRICAL DEVICE USE WITH THE POWER-ARC 4000, in the INSTALLA- TION section of this manual.

GENERAL INFORMATION

The POWER-ARC 4000 generator is rated at 4000 continuous watts (4400 surge watts). It provides both 120 volt and 240 volt power. You can draw up to 20 amps from either side of the 120 volt duplex recepta- cle, but no more than 37 amps from both sides at once. Up to 18 amps can be drawn from the single 240 volt receptacle.

Electrical loads in watts are calculated by multiplying the voltage rating of the load by the number of amps it

draws. (This information is given on the load device nameplate.) For example, a device rated 115 volts, 2 amps will need 230 watts of power (115 x 2 = 230).

You can use Table B.3, GENERATOR POWER APPLI- CATIONS, to determine the wattage requirements of the most common types of loads you can power with the POWER-ARC 4000. Be sure to read the notes at the bottom of the table.

TO USE THE GENERATOR AS AN AUXILIARY POWER SUPPLY:

1.Start the gasoline engine. See ENGINE OPERA- TION in this section of the manual.

2.Set the current control dial on the output control panel to “GENERATOR.” See Figure B.1.

3.Plug the load(s) into the appropriate 120 volt or 240 volt power receptacle.

NOTE: During welding, the maximum generator out- put for auxiliary loads is 100 watts.

NOTE: You can supply multiple loads as long as the total load does not exceed 4,000 watts. Be sure to start the largest loads first.
