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 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 con-
nection 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."
FIGURE C.7 - LN-8 OR LN-9 WIRE FEEDER
CONNECTION TO THE IDEALARC DC-600
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 CIR-
CUIT POLARITY SWITCH to NEGATIVE.
