this manual for battery charging instructions.
Welding Output Cables
With the engine off, connect the electrode and work
cables to the studs provided. These connections
should be checked periodically and tightened if
necessary.
Listed below are copper cable sizes recommended for
the rated current and duty cycle. Lengths stipulated
are the distance from the welder to work and back to
the welder again. Cable sizes are increased for
greater lengths primarily for the purpose of minimizing
cable voltage drop.

Location / Ventilation
The welder should be located to provide an unrestrict-
ed flow of clean, cool air to the cooling air inlets and
to avoid heated air coming out of the back of the
welder recirculating back to the cooling air inlets
below the exhaust. Also, locate the welder so that the
engine exhaust fumes are properly vented to an
outside area.
Damage to fuel tank may cause fire or explosion.
Do NO
T drill holes in the Ranger 9 base or weld to
the Ranger 9 base.
