CLASSIC® 300D & 300G
IDLER OPERATION
Start the engine with the “Idler” switch in the “High”
position. Allow it to run at high idle speed for several
minutes to warm the engine. See Specifications for
operating speeds.
The idler is controlled by the “Idler” toggle switch on
the welder control panel. The switch has two positions
as follows:
1. In the “High” position, the engine control unit
increases the engine to high idle speed.
2. In the “Auto” / position, the idler oper-
ates as follows:
a. When welding or drawing power for lights or tools
(approximately 100 watts minimum) from the recep-
tacles, the engine operates at high idle speed.
b. When welding ceases or the power load is turned
off, a preset time delay of about 15 seconds starts.
This time delay cannot be adjusted.
c. If the welding or power load is not re-started before
the end of the time delay, the engine control unit
reduces the engine to low idle speed.
AUXILIARY POWER
Start the engine and set the “IDLER” control switch to
the “High Idle” mode. Voltage is now correct at the
receptacles for auxiliary power. This must be done
before a tripped GFCI receptacle can be reset proper-
ly. See the MAINTENANCE section for detailed infor-
mation on testing and resetting the GFCI receptacle.

The AC auxiliary power, supplied as a standard, has a
rating of 3.0 kVA of 115/230 VAC (60 hertz).
With the 3.0 kVA, 115/230 VAC auxiliary power, one
115V duplex and one 230V duplex, grounding type
receptacle are provided. The circuit is protected with
circuit breakers.
The rating of 3.0 kVA permits a maximum continuous
current of 13 amps to be drawn from the 230 volt
duplex receptacle. Or a total of 26 amps can be drawn
from the 115 volt duplex receptacle. The 115 volt
duplex receptacle has a configuration which permits 20
amps to be drawn from either half. The total combined
load of all receptacles is not to exceed 3.0 kVA.
An optional power plug kit is available. When this kit is
specified, the customer is supplied with a plug for each
receptacle.
When the High Speed Adjustment knob is in the MIN
position, the frequency of the AC auxiliary output may
be reduced to approximately 55 Hertz. It is recom-
mended that the High Idle Speed Adjustment knob
should be in the MAX position when using the AC aux-
iliary output.
