VANTAGE 549
CAUTION
•
Loose connections will cause the output terminals to
overheat. The terminals may eventually melt.
•
Do not cross the welding cables at the output terminal
connection. Keep the cables isolated and separate from
one another.
Machine GroUnDinG
Because this portable engine driven welder creates its own power,
it is not necessary to connect its frame to an earth ground, unless
the machine is connected to premises wiring (home, shop, etc.).
To prevent dangerous electric shock, other equipment powered by
this engine driven welder must:
a) be grounded to the frame of the welder using a grounded type
plug, or
b) be double insulated.
When this welder is mounted on a truck or trailer, its frame must
be securely connected to the metal frame of the vehicle. When
this engine driven welder is connected to premises wiring such as
that in a home or shop, its frame must be connected to the system
earth ground. See further connection instructions in the section
entitled "Standby Power Connections" as well as the article on
grounding in the latest National Electrical Code and the local
codes.
In general, if the machine is to be grounded, it should be
connected with a #8 or larger copper wire to a solid earth ground
such as a metal ground stake going into the ground for at least
10Ft.(3.1m) or to the metal framework of a building which has
been effectively grounded. The National Electric Code lists a
number of alternate means of grounding electrical equipment. A
machine grounding stud marked with the symbol
on the front of the welder.
aUXiliarY power receptacles
Start the engine and set the "IDLE/RUN/STOP" 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 can be
reset properly. See the MAINTENANCE section for more detailed
information on testing and resetting the GFCI.
The auxiliary power of the VANTAGE® 549 consists of two 20
Amp-120 VAC (5-20R) duplex receptacles with GFCI protection,
one 50 Amp 120/240 VAC (14-50R) receptacle and one 50 Amp
240VAC Three-Phase (15-50R) receptacle.
The auxiliary power capacity is 11,000 Watts Continuous of 60 Hz,
single phase power. The auxiliary power capacity rating in watts is
equivalent to volt-amperes at unity power factor. The max
permissible current of the 240 VAC output is 50amps.
The 240 VAC output can be split to provide two separate 120 VAC
outputs with a max permissible current of 50 Amps per output to
two separate 120 VAC branch circuits (these circuits cannot be
paralleled). Output voltage is within ± 10% at all loads up to rated
capacity.
The Three-Phases auxiliary power capacity is 19,000 watts
continuous. The maximum current is 50 amps.

A GFCI protects the two 120V auxiliary power receptacles.
A GFCI (Ground Fault Circuit Interrupter) is a device to protect
against electric shock should a piece of defective equipment
connected to it develop a ground fault. If this situation should
occur, the GFCI will trip, removing voltage from the output of the
receptacle. If a GFCI is tripped see the MAINTENANCE section for
detailed information on testing and resetting it. A GFCI should be
properly tested at least once every month.
The 120 V 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.
is provided
NOTE: The 240 V receptacle has two 120 V circuits, but are of
opposite polarities and cannot be paralleled.
All auxiliary power is protected by circuit breakers. The 120V has
20 Amp circuit breakers for each duplex receptacle. The 120/240V
Single Phase and the 240V Three-Phases have a 50 Amp 3-pole
Circuit Breaker that disconnects both hot leads and all Three
Phases simultaneously. (See Figure A.3)
