SAFETY PRECAUTIONS
WARNING
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.
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
The VRD reduces the OCV (Open Circuit Voltage) at the welding output terminals while not welding to less than 13V DC when the resistance of the output circuit is above 200⏐ (ohms).
The VRD requires that the welding cable connections be kept in good electrical condition because poor connections will contribute to poor starting. Having good electrical con- nections also limits the possibility of other safety issues such as
The machine is shipped with the VRD switch in the “ON” 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 unrestrict- ed 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 prop- erly vented to an outside area.
STACKING
VANTAGE® 400 (AU) 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 capacity will be slightly less than the amount specified.
LIFTING
The VANTAGE® 400 (AU) weighs approximately 1383 lbs. (627kg.) with a full tank of fuel, 1230 lbs. (559kg.) less fuel. A lift bail is mounted to the machine and should always be used when lifting the machine.
