SAFETY PRECAUTIONS
WARNING
Do not attempt to use this equipment until you have
thoroughly read all operating and maintenance manuals
supplied with your machine. They include important safety
precautions, detailed engine starting, operating and
maintenance instructions and parts lists.
ELECTRIC SHOCK can kill.
•
Do not touch electrically live parts such as
output terminals or internal wiring.
•
Insulate yourself from the 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

VRD (VOLTAGE REDUCTION DEVICE)
The VRD reduces the OCV (Open Circuit Voltage) at the welding
output terminals while not welding to less than 30 VDC when the
resistance of the output circuit is above 200Ω (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 connections also limits the
possibility of other safety issues such as heat-generated damage,
This machine has two VRD switches to allow VRD to be switched
"ON" or "OFF" in CC modes, CV modes, or both. The machine is
shipped with both VRD switches in the "OFF" position.
To utilize the CrossLinc feature on this product, the VRD needs to
be switched "OFF" for the given output type.
To turn VRD "ON" or "OFF":
•
Turn the engine "OFF"
•
Disconnect the negative battery cable
•
Lower the front panel by removing 4 mounting screws (See
Figure A.1)
•
Place the VRD switches in the "ON" or "OFF" position (See
Figure A.2).
NOTE: Use the "CC" switch to enable/disable VRD in CC
modes or the "CV" switch to enable/disable VRD in CV
modes

LOCATION AND VENTILATION
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.
WARNING
Air to cool the engine is drawn in the front and side and
exhausted through radiator and case back. It is important
that the intake and exhaust air is not restricted. Allow a
minimum clearance of 1ft. (0.6m) from the case back and
16 in. (406mm) from either side of the base to a vertical
surface. (Failure to resolve these guidelines may result in
an overtemp condition resulting in engine shut down).
WARNING
DO NOT MOUNT OVER
COMBUSTIBLE SURFACES
Where there is a combustible surface directly under
be covered with a steel plate at least .06"(1.6mm) thick,
which should extend not less than 5.90"(150mm) beyond the
equipment on all sides.
