ELECTRICAL OUTPUT
CONNECTIONS

receptacles, weld output terminals, and ground stud.

WELDING CABLE CONNECTIONS

CABLE INSTALLATION AND CABLE SIZES

With the engine off, connect the electrode and work
cables to the terminals located on the fuel tank mount-
ing rail. (See size recommendations below.) For posi-
tive polarity, connect the electrode cable to the terminal
marked Positive (+). For Negative polarity, connect the
electrode cable to the Negative (-) terminal. These con-
nections should be checked periodically and tightened
if necessary.

• Loose connections will cause the output terminals 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.

When welding at a considerable distance from the
welder, be sure you use ample size welding cables.
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.
