WELDING CABLE CONNECTIONS

CABLE SIZE AND LENGTH

Be sure to use welding cables that are large enough.
The correct size and length becomes especially impor-
tant 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 information.

CABLE INSTALLATION

Install the welding cables to your RANGER 300 as fol-
lows. See Figure A.1 for location of parts.
1. The diesel engine must be OFF to install welding
cables.
2. Remove the flanged nuts from the weld output ter-
minals.
3. Connect the electrode holder and work cables to
the weld output terminals. The terminals are iden-
tified 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.
INSTALLATION
• 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.
AUXILIARY POWER RECEPTACLES,
PLUGS, AND HAND-HELD EQUIPMENT
The control panel of the RANGER 300 features three
auxiliary power receptacles. See Figure A.1.
• Two 15 amp, 120 volt duplex (double outlet) recep-
• One 50 amp 120/240 volt simplex (single outlet)
Through these receptacles the machine can supply up

CIRCUIT BREAKERS

The RANGER 300 machines are equipped with 50
amp circuit breakers on the 120/240 V receptacle and
15 amp circuit breakers on the 120 V receptacles for
overload protection. Under high heat a breaker may
tend to trip at lower loads than it would normally.
