VANTAGE 400

SAFETY PRECAUTIONS

Do not attempt to use this equipment until you have thor-
oughly read the engine manufacturer's manual supplied
with your welder. It includes important safety precautions,
detailed engine starting, operating and maintenance instruc-
tions, and parts lists.
--------------------------------------------------------------------
ELECTRIC SHOCK can kill.
• Do not touch electrically live parts or elec-
trode with skin or wet clothing.
• Insulate yourself from work and ground
• Always wear dry insulating gloves.
--------------------------------------------------------------------
ENGINE EXHAUST can kill.
• Use in open, well ventilated areas or vent
exhaust outside.
--------------------------------------------------------------------
MOVING PARTS can injure.
• Do not operate with doors open or guards
off.
• Stop engine before servicing.
• Keep away from moving parts.
--------------------------------------------------------------------
See additional warning information at front of this
operator's manual.
Only qualified personnel should install,
use, or service this equipment.

VRD (VOLTAGE REDUCTION DEVICE)

The VRD feature provides additional safety in the CC-Stick mode especially
in an environment with a higher risk of electric shock such as wet areas and
hot humid sweaty conditions.
The VRD reduces the OCV (Open Circuit Voltage) at the welding output ter-
minals while not welding to less than 30V DC when the resistance of the
output circuit is above 200 (ohms).
The VRD requires that the welding cable connections be kept in good elec-
trical condition because poor connections will contribute to poor starting.
Having good electrical connections also limits the possibility of other safety
issues such as heat-generated damage, burns and fires.
The machine is shipped with the VRD switch in the "Off" position. To turn it
"On" or "Off".
• Turn the engine "Off".
• Disconnect the negative battery cable.
• Lower the control panel by removing 4 front panel screws. (See Figure
A.1)
• Place the VRD switch in the "On" or "Off" position. (See Figure A.1)
With the VRD switch in the "On" position, the VRD lights are enabled.

LOCATION AND VENTILATION

The welder should be located to provide an unrestricted flow of
clean, cool air to the cooling air inlets and to avoid restricting the
cooling air outlets. Also, locate the welder so that the engine
exhaust fumes are properly vented to an outside area.

STACKING

VANTAGE 400 machines cannot be stacked.

ANGLE OF OPERATION

Engines are designed to run in the level condition which is where
the optimum performance is achieved. The maximum angle of
continuous operation is 25 degrees in all directions, 35 degrees
Intermittent (less than 10 minutes continuous) in all directions. If
the engine is to be operated at an angle, provisions must be
made for checking and maintaining the oil level at the normal
(FULL) oil capacity in the crankcase.
When operating the welder at an angle, the effective fuel capaci-
ty will be slightly less than the amount specified.

LIFTING

The VANTAGE 400 weighs approximately 1345lbs. (611kg.) with
a full tank of fuel 1230lbs.(559kg) less fuel. A lift bail is mounted
to the machine and should always be used when lifting the
machine.
