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 connection 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: The connection diagram shown in Figure C.5 shows the
electrode connected for positive polarity.
To change polarity:
a. Set the Idealarc DC-600 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-600 CONTROL CIRCUIT
POLARITY SWITCH to NEGATIVE.
e. Reverse the leads at the back of the ammeter and
voltmeter on the wire feeder automatic control box.
CONNECTING THE
IDEALARC DC-600
Note: For optimum performance use the NA-5 with Idealarc DC-
600 codes 8288 and above.
1. Disconnect main AC input power to the Idealarc DC-600.
2. Set the Idealarc DC-600 ON/OFF PUSH BUTTON to OFF.
3. Connect the wire feeder control cable leads to the Idealarc
DC-600 amphenol/terminal strip as shown in Figure C.6.

TO WORK
Note: If using a K215 control cable, connect control cable leads
#75, #76, and #77 to the matching #75, #76, and #77 terminals on
the terminal strip of the Idealarc DC- 600.
4. Connect the wire feeder control cable ground lead to the
frame terminal marked (
Note: The Idealarc DC-600 must be properly grounded.
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 connection 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.

6. Connect NA-5 wire feeder control jumpers on Voltage
Control Board. See NA-5 Operator's Manual.
a. Connect red jumper on Voltage Control Board to pin "S."
b. Connect white jumper on Voltage Control Board to pin "B."
Note: The connection diagram shown in Figure C.6 shows the
electrode connected for positive polarity.
To change polarity:
a. Set the Idealarc DC-600 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-600 CONTROL CIRCUIT
POLARITY SWITCH to NEGATIVE.
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 OR LN-9 TO THE
IDEALARC DC-600
1. Disconnect AC input power to the Idealarc DC-600.
2. Set the Idealarc DC-600 ON/OFF PUSH BUTTON to OFF.
3. Connect the wire feeder control cable leads to the Idealarc
DC-600 amphenol/terminal strip as shown in Figure C.7.
4. Connect the wire feeder control cable ground lead to the
frame terminal marked (
Note: The Idealarc DC-600 must be properly grounded.
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 connection 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.
a. White jumper on Voltage Control Board to pin "S."
b. Blue jumper on Voltage Control Board to pin "B."
Note: On earlier units, the blue jumper on Voltage Control Board
is connected to Pin "B" on Start Board.
Note: The connection diagram shown in Figure C.7 shows the
electrode connected for positive polarity.
To change polarity:
a. Set the Idealarc DC-600 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-600 CONTROL CIRCUIT
POLARITY SWITCH to NEGATIVE.
