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.
NO
TE: 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).
