CLASSIC® 300D & 300G
AUXILIARY POWER
If a GFCI receptacle is tripped, See the MAINTE-
NANCE section for detailed information 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 GFCI and one 230V duplex, grounding type
receptacles 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 20 amps can be drawn
from the 115 volt GFCI receptacle. 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.
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 idler solenoid deac-
tivates, and the engine goes to high idle speed. The
speed is controlled by the governor.
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
receptacles, the idler solenoid deactivates and 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 idler solenoid
activates and reduces the engine to low idle
speed.
