IDEALARC DC-600
CONNECTIONS FOR SEMI-AUTO-
MATIC OR AUTOMATIC WIRE
FEEDER CONTROL
1.
Set the ON/OFF PUSH BUTTON to OFF.
2.
Locate and open the hinged access door on the
Front Case Assembly.
3.
Insert control cable through the strain relief box
connector and pull enough cable through to reach
the terminal strip.
4.
Connect the automatic wire feeder control cable to
the terminal strip. See corresponding connection
diagram in this Section of the manual, or the
instructions included with the wire feeder.
5.
Connect the wire feeder grounding wire to the
chassis ground screw marked with the symbol ( ).
NOTE: The IDEALARC DC-600 Auxiliary Power
Circuit supplies 115-volt AC power to the wire feed-
ing equipment. The circuit has a 1000 volt ampere
rating. An 8-amp slow blow fuse on the machine’s
control panel protects the auxiliary power supply
from excessive overloads.
CONNECTING THE NA-3 IDEALARC DC-600
1.
Disconnect main AC input power to the IDEALARC
DC-600.
2.
Set 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.5.
4.

CONNECTION TO THE IDEALARC DC-600
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: The connection diagram shown in Figure C.5
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.
e.
Reverse the leads at the back of the ammeter
and voltmeter on the wire feeder automatic
control box.
