ACCESSORIES
C-4
NOTE: The connection diagram shown in Figure C.2
shows the electrode connected for positive polarity.
To change polarity:
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. Set the IDEALARC DC-1000 CONTROL
CIRCUIT POLARITY SWITCH to NEGA-
TIVE.
e. Refer to NA-5 operator’s manual for proper
control box polarity connections.
NOTE: For proper NA-5 operation, the electrode
cables must be secured under the clamp bar on the
left side of the NA-5 Control Box.
CONNECTING THE LN-8 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.3.
4. Connect the wire feeder control cable ground lead
to the frame terminal marked .
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 electrically 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 #76 on the terminal strip.
8. Connect lead #77(C) to #77 on the terminal strip.
9. Connect the welding cables as shown in Figure
C.3.
NOTE: Welding cables must be of proper capacity for
the current and duty cycle for immediate and future
applications.
10. Set the DC-1000 output control switch to the
”Output Control Remote” position.
NOTE: The connection diagram shown in figure C-3
shows electrode connected positive. To change polari-
ty:
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. Set the IDEALARC DC-1000 CONTROL
CIRCUIT POLARITY SWITCH to NEGA-
TIVE.
e. Refer to LN-8 operator’s manual for proper
control box polarity connections.
CAUTION
The IDEALARC DC-1000 must be properly grounded.
