AUXILIARY POWER OPERATION

Start the engine and set the IDLER control switch to the desired operating mode. Full power is available regardless of the welding control settings, if no welding current is being drawn..

The auxiliary power of the Commander consists of two- 120VAC (5-15R) duplex receptacles with GFCI protec- tion and one 120/240 VAC (14-50R) receptacle. The 120/240VAC receptacle can be split for single phase 120 VAC operation.

The auxiliary power capacity is 10,000 watts of 60 Hz, single phase power. The auxiliary power capacity rat- ing in watts is equivalent to volt-amperes at unity power factor. The maximum permissible current of the 240 VAC output is 44 A. The 240 VAC output can be split to provide two separate 120 VAC outputs with a maximum permissible current of 44 A per output to two separate 120 VAC branch circuits. Output voltage is within ± 10% at all loads up to rated capacity.

NOTE: The 240V receptacle has two 120V outlets of different phases and cannot be paralleled.

The auxiliary power receptacles should only be used with three wire grounded type plugs or approved dou- ble insulated tools with two wire plugs.

The current rating of any plug used with the system must be at least equal to the current capacity of the associated receptacle.

SIMULTANEOUS WELDING AND AUXIL- IARY POWER LOADS

It must be noted that the above auxiliary power ratings are with no welding load. Simultaneous welding and power loads are specified in table B.4. The permissible currents shown assume that current is being drawn from either the 120 VAC or 240 VAC supply (not both at the same time).
