Lincoln Electric IM751 POWER-ARC 4000 - Manual (Page 20)

GENERATOR OPERATION
Be sure that any electrical equipment plugged into
the generator’s AC power receptacles can with-
stand a ±10% voltage and a ±4% frequency varia-
tion. 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 INSTALLATION 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 and the engine
owner’s 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.
CAUTION
B-5 OPERATION B-5
STOPPING THE ENGINE
1. Remove all welding and generator power loads
and let the engine cool by running it for several
minutes.
2. Stop the engine by placing the ignition switch in
the “OFF” position.
3. Close the fuel shutoff valve.
Close the fuel valve when the machine is trans-
ported to prevent fuel leakage from the carbure-
tor. Drain the tank before transporting the
machine in a vehicle.
For long periods of storage, turn off the fuel shut-
off valve (lowest, downward position) and let the
engine run until there is no more fuel in the line.
Use a fuel additive such as Sta-Bil to minimize fuel
gum deposits.
-----------------------------------------------------------
RUNNING THE ENGINE
The engine is set at the factory to run at high idle
speed when not under load. You should not adjust
this setting yourself.
BREAK-IN PERIOD
The engine will use a greater amount of oil during its
“break-in” period. Check the oil frequently during
break-in. For more details, see the MAINTENANCE
section in the engine owner’s manual.
During break-in, subject the POWER-ARC 4000 to
only moderate loads. Avoid long periods running
at idle. Before stopping the engine, remove all
loads and allow the engine to cool several min-
utes.
