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
Δ Δ
20 Amp-120VAC (5-20 R) duplex receptacles and one
50 Amp-120/240 VAC (14-50R) receptacle. The
120/240VAC receptacle can be split for single phase
120 VAC operation.
Δ
15 Amps for codes below 10500.
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 120/240V receptacle has two 120V out-
puts 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 permissi-
ble currents shown assume that current is being drawn
from either the 120 VAC or 240 VAC supply (not both
at the same time).
