CONNECTIONS
See Figure A.1 for the location of the 115 and 230 volt
receptacles, weld output terminals, and ground stud.
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 and
connect to the terminals located below the fuel tank
mounting rail. (See size recommendations below.) For
positive polarity, connect the electrode cable to the ter-
minal marked Positive (+). For Negative polarity, con-
nect 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 the
properly specified welding cables. See the
Accessories section of this manual for more
information.
