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 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.
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."

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.
