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 posi- tions 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 com- bined 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 auxiliary output.
