WELDING OUTPUT CABLES
With the engine off, route the electrode and work
cables through the strain relief bracket provided on the
front of the base and connect to the terminals provided.
These connections should be checked periodically and
tightened if necessary.
Listed in Table A4.1 are copper cable sizes recom-
mended for the rated current and duty cycle. Lengths
stipulated are the distance from the welder to work and
back to the welder again. Cable sizes are increased for
greater lengths primarily for the purpose of minimizing
cable voltage drop.

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 con-
nected 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 sec-
tion entitled
Standby Power Connections
as well as
the article on grounding in the latest U.S. National
Electrical Code and the local code.
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 water pipe going into the
ground for at least ten feet and having no insulated
joints, or to the metal framework of a building which has
been effectively grounded. The U.S. National Electrical
Code lists a number of alternate means of grounding
electrical equipment. A machine grounding stud
marked with the symbol is provided on the front of
the welder.
AUXILIARY POWER RECEPTACLES
The auxiliary power capacity of the Vantage 500 is
12,000 watts of 60 Hz, single-phase power. The auxil-
iary power capacity rating in watts is equivalent to volt-
amperes at unity power factor. The maximum permis-
sible current of the 240 VAC output is 50 A. The 240
VAC 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 cir-
cuits. The output voltage is within ± 10% at all loads up
to rated capacity.
NOTE:
The 120/240V receptacle has two 120V outlets
of different phases and cannot be paralleled.
The Vantage has two 20A-120VAC (5-20R) duplex
receptacles and one 50A-120/240 VAC (14-50R)
receptacle. The 120/240 VAC receptacle can be split
for single-phase 120 VAC operation. 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 cur-
rent capacity of the associated receptacle.
STANDBY POWER CONNECTIONS
The Vantage 500 is suitable for temporary, standby or
emergency power using the engine manufac turer’s
recommended maintenance schedule.
The Vantage 500 can be permanently installed as a
standby power unit for 240 volt, three-wire, 50 amp ser-
vice. Connections must be made by a licensed electri-
cian who can determine how the 120/240 VAC power
can be adapted to the particular installation and com-
ply with all applicable electrical codes. The following
information can be used as a guide by the electrician
for most applications. Refer to the connection diagram
shown in
Figure A4.1.
