CONNECTING THE LN-9 WIRE FEEDER
TO THE IDEALARC DC-1000
1. Set the ON/OFF PUSH BUTTON to the OFF pos-
tion.
2. Disconnect AC input power to the IDEALARC DC-
1000.
3. Connect the wire feeder control cable leads to the
DC-1000 terminal strip. See Figure C.4.
4. Connect the wire feeder control cable ground lead
to the frame terminal marked
CAUTION
The IDEALARC DC-1000 must be properly grounded.
____________________________________________________
5. Extend the wire feeder control cable #21 lead so it
can be connected directly to the work piece.
a. Make a bolted connection using AWG #14
or larger insulated wire.
b. Tape the bolted connection with insulating
tape.
NOTE: An S-16586-X remote voltage sensing work
lead is available for this purpose.
c. Keep the #21 lead elecrically separate
from the work cable circuit and connection.
d. Tape the #21 lead to the work cable for
ease of use.
6. Connect lead #75(A) to #75 on the terminal strip.
7. Connect lead #76(B) to #74 on the terminal strip.
8. Connect lead #77(C) to #73 on the terminal strip.
9. Connect the welding cables as shown in Figure
C.4.
Note: Welding cables must be of proper capacity for
the current and duty cycle for immediate and future
applications.
10. Connect LN-9 wire feeder jumpers on voltage
board as follows: See LN-9 operator's manual.
a. White jumper on voltage board to pin "S"
b. Blue jumper on voltage board (later mod-
els) or on start board (earlier models) to
pin "B".

11. Set the DC-1000 output control switch to the
"Output Control Remote" position.
NOTE: The connection diagram shown in figure C-4
shows electrode connected for positive polarity. To
change polarity:
IDEALARC DC-1000
to the IDEALARC DC-1000
a. Set the IDEALARC DC-1000 ON/OFF
PUSH BUTTON to OFF.
b. Move the electrode cable to the Negative
(-) output terminal.
c. Move the work cable to the Positive (+)
output terminal.
d. Position the positive-negative switch on
the power source to correspond to the
polarity of the electrode cable connection.
e. Refer to LN-9 operating manual for
required polarity connections.
