CONNECTING THE LN-8 OR LN-9 TO THE IDEALARC DC-400 (TERMINAL STRIP)

1.Disconnect main AC input power to the Idealarc DC-400.

2.Set the Idealarc DC-400 POWER toggle switch to the OFF (0) position.

3.Connect the wire feeder control cable leads to the Idealarc DC-400 terminal strip as shown in Figure C.9.

4.Connect the wire feeder control cable ground lead

to the frame terminal marked .

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.

NOTE: The connection diagram shown in Figure C.9 shows the electrode connected for positive polarity. To change polarity:

a.Set the Idealarc DC-400 POWER toggle switch to the OFF (0) position.

b.Move the electrode cable to the negative (-) output terminal.

c.Move the work cable to the positive (+) output terminal.

d.Set the VOLTMETER toggle switch to negative (-).

7.Set the OUTPUT CONTROL switch to the “Remote” position and the OUTPUT TERMINALS switch to the “Remote” position.
