FIGURE C.4 - LN-8 OR LN-9 WIRE FEEDER CONNECTION TO THE IDEALARC DC-655
CONNECTING THE LN-8 OR LN-9 TO THE
IDEALARC DC-655 (TERMINAL STRIP)
1. Set the Idealarc DC-655 POWER toggle switch to
the OFF (0) position.
2. Disconnect main AC input power to the Idealarc
DC-655.
3. Connect the wire feeder control cable leads to the
Idealarc DC-655 terminal strip as shown in Figure
C.4.
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.
