ELECTRICAL CONNECTIONS
See Figure B.1 in the OPERATION section of this
manual for the location of the 115 and 230 volt recep-
tacles, weld output terminals, circuit breakers and
ground stud.
MACHINE GROUNDING
Because the RANGER 8+ DIESEL creates its own
power from its diesel-engine driven generator, and if
the machine is not connected to premises wiring
(home, shop, etc.), you do not need to connect the
machine frame to an earth ground. However, for best
protection against electrical shock, connect a heavy
gauge wire (#8 AWG or larger) from the ground stud
located on the bottom of the output panel (See Figure
B.1) to a suitable earth ground such as a metal pipe
driven into the ground.
Do not ground the machine to a pipe that carries
explosive or combustible material.
------------------------------------------------------------------------
When the RANGER 8+ DIESEL is mounted on a truck
or a trailer, the machine generator ground stud MUST
be securely connected to the metal frame of the vehi-
cle. See Figure B.1. The ground stud is marked with
the ground symbol.
If the RANGER 8+ DIESEL is connected to premises
wiring such as a home or shop, it must be properly
connected to the system earth ground.
WELDING CABLE CONNECTIONS
CABLE SIZE AND LENGTH
Be sure to use welding cables that are large enough.
The correct size and length becomes especially
important when you are welding at a distance from the
welder.
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.
Lincoln Electric offers a welding accessory kit with the
properly specified welding cables. See the
ACCESSORIES section of this manual for more infor-
mation.
WARNING
Table A.1
CABLE INSTALLATION
Install the welding cables to your RANGER 8+
DIESEL as follows. See Figure B.1 for location of
parts.
1. The diesel engine must be OFF to install welding
cables.
2. Remove the flanged nuts from the output terminals.
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 terminals to
overheat. The terminals may eventually melt.
• Do not cross the welding cables at the output termi-
nal connection. Keep the cables isolated and sepa-
rate from one another.
