CABLE INSTALLATION
Install the welding cables to your machine as follows:
1. The diesel engine must be OFF to install welding
cables.
2. Remove the flanged nuts from the output termi-
nals.
3. Connect the electrode holder and work cables to
the weld output terminals. The terminals are identi-
fied on the case front.
4. Tighten the flanged nuts securely.
5. Be certain that the metal piece you are welding
(the “work”) is properly connected to the work
clamp and cable.
6. Check and tighten the connections periodically.
• Loose connections will cause the output termi-
nals to overheat. The terminals may eventually
melt.
• Do not cross the welding cables at the output
terminal connection. Keep the cables isolated
and separate from one another.

AUXILIARY POWER
The auxiliary power capacity is 8500 watts Peak,
8,000 Watts Continuous of 50 Hz, three phase
power. The auxiliary power capacity rating in watts is
equivalent to volt-amperes at unity power factor. The
max permissible current of the 400 VAC output is 12
amps. Output voltage is within ± 10% at all loads up
to the rated capacity.
STANDBY POWER CONNECTIONS
The machine is suitable for temporary, standby or
emergency power using the engine manufacturerʼs
recommended maintenance schedule.
The machine can be permanently installed as a
standby power unit for 400 VAC, three phase, 12
amp service.
Connections must be made by a licensed electrician
who can determine how the power can be adapted to
the particular installation and comply with all applica-
ble electrical codes.
• Take necessary steps to assure load is limited to
the capacity of the RANGER® 305D (CE).
• Only a licensed, certified, trained electrician
should install the machine to a premises or resi-
dential electrical system. Be certain that:

When this welder is mounted on a truck or trailer, its
frame must be electrically bonded to the metal frame of
the vehicle. Use a #8 or larger copper wire connected
between the machine grounding stud and the frame of
the vehicle. When this engine driven welder is connect-
ed to premises wiring such as that in a home or shop,
its frame must be connected to the system earth
ground. See further connection instructions in the sec-
tion entitled "Standby Power Connections" .
In general, if the machine is to be grounded, it should
be connected with a #8 or larger copper wire to a solid
earth ground such as a metal water pipe going into the
ground for at least ten feet and having no insulated
joints, or to the metal framework of a building which
has been effectively grounded.
A machine grounding stud marked with the symbol
is provided on the front of the welder.
WELDING TERMINALS
The machine is equipped with a toggle switch for
selecting "hot" welding terminal when in the "WELD
TERMINALS ON" position or "cold" welding terminal
when in the "REMOTE" position.
WELDING OUTPUT CABLES
With the engine off connect the electrode and work
cables to the output studs. The welding process dic-
tates the polarity of the electrode cable. These connec-
tions should be checked periodically and tightened with
a 19mm wrench.
Table A.1 lists recommended cable sizes and lengths
for rated current and duty cycle. Length refers to the
distance from the welder to the work and back to the
welder. Cable diameters are increased for long cable
lengths to reduce voltage drops.
