CONNECTING THE LN-9 WIRE FEEDER 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.4.

4.Connect the wire feeder control cable ground lead

to the frame terminal marked .

CAUTION

The IDEALARC DC-1000 must be properly grounded.

____________________________________________________

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 elecrically 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 #74 on the terminal strip.

8.Connect lead #77(C) to #73 on the terminal strip.

9.Connect the welding cables as shown in Figure C.4.

Note: Welding cables must be of proper capacity for the current and duty cycle for immediate and future applications.

10.Connect LN-9 wire feeder jumpers on voltage board as follows: See LN-9 operator’s manual.

a.White jumper on voltage board to pin “S”

b.Blue jumper on voltage board (later mod- els) or on start board (earlier models) to pin “B”.

11.Set the DC-1000 output control switch to the ”Output Control Remote” position.

NOTE: The connection diagram shown in figure C-4 shows 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.Position the positive-negative switch on the power source to correspond to the polarity of the electrode cable connection.

e.Refer to LN-9 operating manual for required polarity connections.
