WELDING OUTPUT CAbLES
With the engine off connect the electrode and work
cables to the output studs. The welding process dic-
tates the polarity of the electrode cable. These con-
nections should be checked periodically and tightened
with a 3/4" wrench.
Table A.1 lists recommended cable sizes and lengths
for rated current and duty cycle. Length refers to the
distance from the welder to the work and back to the
welder. Cable diameters are increased for long cable
lengths to reduce voltage drops.
TAbLE A.1
TOTAL COMbINED LENGTH OF
ELECTRODE AND WORK CAbLES
Cable Length
0-100Ft. (0-30 meters)
100-150 Ft. (30-46 meters)
150-200 Ft. (46-61 meters)
CAbLE INSTALLATION
Install the welding cables to your VANTAGE® 300 as
follows.
1. The engine must be OFF to install welding cables.
2. Remove the flanged nuts from the output terminals
.
3. Connect the electrode holder and work cables to
the weld output terminals. The terminals are identi-
fied on the case front.
4. Tighten the flanged nuts securely.
5. Be certain that the metal piece you are welding (the
"work") is properly connected to the work clamp and
cable.
6. Check and tighten the connections periodically.
CAUTION
• Loose connections will cause the output termi-
nals to overheat. The terminals may eventually
melt.
• Do not cross the welding cables at the output ter-
minal connection. Keep the cables isolated and
separate from one another.

AUXILIARY POWER RECEPTACLES
Start the engine and set the "IDLER" control switch to the
"High Idle" mode. Voltage is now correct at the recepta-
cles for auxiliary power. This must be done before a
tripped GFCI module can be reset properly. See the
MAINTENANCE section for more detailed information on
testing and resetting the GFCI module
The auxiliary power of the VANTAGE® 300 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 11,500 watts Peak,
10,000 Watts Continuous of 60 Hz, single phase
power. The auxiliary power capacity rating in watts is
Cable Size for
equivalent to volt-amperes at unity power factor. The
400 Amps
max permissible current of the 240 VAC output is
60% Duty Cycle
42amps.
2 / 0 AWG
The 240 VAC output can be split to provide two sepa-
2 / 0 AWG
rate 120 VAC outputs with a max permissible current
of 42 Amps per output to two separate 120 VAC
3 / 0 AWG
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 12,500
watts peak, 11,000 watts continuous. The maximum
current is 27 amps.
120 V DUPLEX RECEPTACLES AND GFCI
MODULES
A GFCI Module 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 module will trip, remov-
ing voltage from the output of the receptacle. If a GFCI
module is tripped see the MAINTENANCE section for
detailed information on testing and resetting it. A GFCI
module 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.
