d.Tape the #21 lead to work cable for ease of use.

6.Connect the welding cables as shown in Figure C.1.

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

NOTE: The connection diagram shown in Figure C.1 shows the 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.Set the IDEALARC DC-1000 CONTROL CIRCUIT POLARITY SWITCH to NEGA- TIVE.

e.Reverse the leads at the back of the ammeter and voltmeter on the wire feeder automatic control box.

CONNECTING THE NA-5 TO THE IDEALARC DC-1000

NOTE: For optimum performance, use the NA-5 with IDEALARC DC-1000 codes 8288 and above.

1.Disconnect main AC input power to the IDE- ALARC DC-1000.

2.Set the IDEALARC DC-1000 ON/OFF PUSH BUTTON to OFF.

3.Connect the wire feeder control cable leads to the IDEALARC DC-1000 terminal strip as shown in Figure C.2.

NOTE: If using a K215 control cable, connect con- trol cable leads #75 to #75 on the terminal strip, #76 to #74 on the terminal strip, and #77 to #73 on the terminal strip.

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 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.

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 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 the 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.”

7.Connect the welding cables as shown in Figure C.2.

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