SAFETY PRECAUTIONS
Do not attempt to use this equipment until you
have thoroughly read the engine manufacturer’s
manual supplied with your welder. It includes
important safety precautions, detailed engine
starting, operating and maintenance instructions,
and parts lists.
------------------------------------------------------------------------
ELECTRIC SHOCK can kill.
• Do not touch electrically live parts or
electrode with skin or wet clothing.
• Insulate yourself from work and
ground
• Always wear dry insulating gloves.
• Always operate the welder with the hinged door
closed and the side panels in place.
• Read carefully the Safety Precautions page
before operating this machine. Always follow
these and any other safety procedures included
in this manual and in the Engine Instruction
Manual.
GENERAL DESCRIPTION
The VANTAGE® 400 is a diesel engine powered DC
multi-process welding power source and 120 / 240 volt
AC power generator. The engine drives a generator
that supplies three phase power for the DC welding cir-
cuit, single phase and Three Phase power for the AC
auxiliary outlets. The DC welding control system uses
state of the art Chopper Technology (CT™) for superi-
or welding performance.
The Vantage® 400 is fitted with a selectable
VRD(Voltage Reduction Device). The VRD operates in
the CC-Stick mode reducing the OCV to <13 volts,
increasing operator safety when welding is performed
in environments with increased hazard of electric
shock.
FOR AUXILIARY POWER:
Start the engine and set the IDLER
control switch to the desired operating mode. Full
power is available regardless of the welding control
settings providing no welding current is being drawn.
ENGINE OPERATION
Before Starting the Engine:
• Be sure the machine is on a level surface.
• Open side engine door and remove the engine oil
dipstick and wipe it with a clean cloth. Reinsert the
dipstick and check the level on the dipstick.
• Add oil (if necessary) to bring the level up to the full
mark. Do not overfill. Close engine door.
• Check radiator for proper coolant level. (Fill if nec-
essary).
• See Engine Owner’s Manual for specific oil and
coolant recommendations.
ADD FUEL
• Stop engine while fueling.
• Do not smoke when fueling.
• Keep sparks and flame away
from tank.
• Do not leave unattended while
fueling.
• Wipe up spilled fuel and allow
fumes to clear before starting
engine.
• Do not overfill tank, fuel expan-
sion may cause overflow.
DIESEL FUEL ONLY
------------------------------------------------------------------------
• Remove the fuel tank cap.
• Fill the tank. DO NOT FILL THE TANK TO THE
POINT OF OVERFLOW.
• Replace the fuel cap and tighten securely.
• See Engine Owner’s Manual for specific fuel recom-
mendations.
BREAK-IN PERIOD
The engine will use a small amount of oil during its
“break-in” period. The break-in period is about 50 run-
ning hours.
Check the oil every four hours during break-in. Change
the oil after the first 50 hours of operation and every
200 hours thereafter. Change the oil filter at each oil
change.
During break-in, subject the Welder to moderate
loads. Avoid long periods running at idle. Before
stopping the engine, remove all loads and allow
the engine to cool several minutes.
