CONNECTING THE LN-8 OR LN-9 TO THE
IDEALARC DC-400 (TERMINAL STRIP)
1.
Disconnect main AC input power to the Idealarc
DC-400.
2.
Set the Idealarc DC-400 POWER toggle switch to
the OFF (0) position.
3.
Connect the wire feeder control cable leads to the
Idealarc DC-400 terminal strip as shown in Figure
C.9.
4.
Connect the wire feeder control cable ground lead
to the frame terminal marked .
5.
Extend wire feeder control cable lead #21 so it can
be connected directly to the work piece.
a. Make a bolted connection using AWG #14 or
larger insulated wire. Tape the bolted connec-
tion with insulating tape.
b. An S-16586- X remote voltage sensing work
lead is available for this purpose.
c. Keep the #21 lead electrically separate from
the work cable circuit and connection.
d. Tape the #21 lead to work cable for ease of
use.
NOTE: Using the extended #21 lead eliminates
the need to use the LN-9’s remote work
lead accessory, which has a direct work
lead jack.
6.
Connect LN-9 wire feeder control jumpers on
Voltage Control board. See LN-9 Operator’s
Manual.
NOTE: The connection diagram shown in Figure C.9
shows the electrode connected for positive

switch to the OFF (0) position.
b. Move the electrode cable to the negative (-)
output terminal.
c. Move the work cable to the positive (+) output
terminal.
