WELDING CABLE CONNECTIONS

CABLE INSTALLATION, POLARITY CONTROL,
AND CABLE SIZES

With the engine off, route the electrode and work
cables through the strain relief bracket on the base
front and connect them to the terminals. (See size rec-
ommendations below.) For positive polarity, connect
the electrode cable to the terminal marked Positive (+).
For Negative polarity, connect the electrode cable to
the Negative (-) terminal. These connections 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 prop-
erly specified welding cables. See the Accessories
section of this manual for more information.
