INPUT CABLE CONNECTIONS
For connecting an LN-8 to a specific Lincoln Electric
power source, use the appropriate steps in one of
these paragraphs and refer to the connection dia-
grams listed on
for the applicable power
lists each figure number with its
corresponding power source.
LN-8N AND LN-8S
The input cable consists of an electrode cable and a
multi-conductor control cable. The control cable has a
polarized plug on the wire feeder end. To connect the
cables, refer to Figure A.11 and perform these steps:
1. Connect the polarized plug of the control cable to
the mating connector on the back of the wire
feeder.

ELECTRODE CABLE CONNECTIONS
2. Remove the screws holding the cable clamp
located near the rear of the wire reel base. Put
the control cable and electrode cable under the
clamp and install the screws. On cables with
more than one electrode cable, leave the junction
between the two or more cables and the single
4/0 stub behind the clamp so only the single
electrode lead is under the clamp.
3. Pass the single electrode cable through the holes
provided in the back corner of the control section
and fasten it to the tab on the conductor above
the rear brass block of the wire feeder.
LN-8NE AND LN-8SE
The extension unit consists of a wire reel mount with
a hand crank and either a 22-1/2 or 45 ft (6.9 or
13.7 m) extension cable assembly. The cable is rated
at 450 amps, 50% duty cycle. For higher currents
install a parallel length of 1/0 cable per step 10. The
extension cable can be used for 0.068 through
0.120 in. (1.7 through 3.0 mm) flux-cored electrode
and 5/64 through 3/32 in. (2.0 through 2.4 mm) solid
electrode. The 22-1/2 ft. (6.9 m) cables can also be
used for 1/16 in. (1.6 mm) solid electrodes. To con-
nect the cables, perform these steps:
1. When shipped, the hand crank on the wire reel
mount is equipped to feed 1/16 through 0.120 in.
(1.6 through 3.0 mm) electrode.
