AUXILIARY POWER OPERATION
Start the engine and set the RUN / STOP / IDLE 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 Vantage
120 VAC (5-20R) duplex receptacles with GFCI protection,
one 50 amp 120/240 VAC single phase (14-50R) receptacle and
one 50 amp 240 VAC three phase (15-50R) receptacle.
The auxiliary power capacity is 11,000 watts of 60 Hz, single
phase power or 19,000 watts of 60 Hz, three phase power. The
auxiliary power capacity rating in watts is equivalent to volt-
amperes at unity power factor. The maximum permissible current
of the 240 VAC output is 50 A. The 240 VAC single phase output
can be split to provide two separate 120 VAC outputs with a
maximum permissible current of 50 A per output to two separate
120 VAC branch circuits. Output voltage is within ± 10% at all
loads up to rated capacity.
NOTE: The two 120V GFCI receptacles and the two 120V circuits
of the 120/240V receptacle are connected to different phases
and cannot be paralleled.
The auxiliary power receptacles should only be used with three
wire grounded type plugs or approved double 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 AUXILIARY POWER
LOADS
The auxiliary power capacity previously stated is maintained
without any welding load. If a welding load is present, the
available auxiliary power will decrease.
Simultaneous welding and power loads are speci ed in Table B.5.
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).
