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 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 terminals while not welding to less than 13V DC 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,
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.

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 20 degrees in all directions, 30 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.
