12. Connect the left cable from the MULTI-PROCESS SWITCH
(facing the front of the machine) to the Idealarc DC-600
negative (-) output terminal. See Figure C.4.
13. Connect the wire feeder electrode and work cables. See
Figure C.4.
a. Insert the wire feeder electrode and work cables through
the strain relief loop on the left side of the Idealarc DC-
600 (facing the front of the machine).
b. Connect the wire feeder electrode and work cables to
the electrode and work terminals on the left side of the
MULTI-PROCESS SWITCH.
Note: When using Dual Process Kits K317 or K318,
connect the electrode and work cables to these terminals
instead of the power source output terminals. See
connection diagrams for details.
14. Connect wire feeder control cable to the amphenol/terminal
strip of the Idealarc DC-600.
Note: Connect the control cable ground lead to the frame
terminal marked ( ).
Note: See the connection diagram for the wire feeder being
used for connection instructions.
15. Connect stick or air/carbon arc electrode and work cable.
See Figure C.4.
a. Insert the electrode and work cables through the strain
relief loop on the right side (facing the front of the
machine) of the Idealarc DC-600.
b. Connect the electrode cable to the "Positive" terminal on
the right side of the MULTI-PROCESS SWITCH.
c. Connect the work cable to the "Negative" terminal on
the right side of the MULTI-PROCESS SWITCH.
Note: The instructions above are for connecting the stick
polarity positive. To change the polarity, turn the Idealarc
DC-600 OFF, and reverse the cables.
Note: When it is not necessary to have separate ground
cables for stick and semi-automatic or automatic welding,
connect a jumper from the MULTI-PROCESS SWITCH
"Work" terminal to the MULTI-PROCESS SWITCH
"negative" terminal. See Figure C.4.
To operate the MULTI-PROCESS SWITCH, refer to the operating
instructions on the switch nameplate.
UNDERCARRIAGE (KA1236, KA1237)
The IDEALARC DC-600 is designed for use with the Lincoln
Undercarriage. Complete installation instructions are included
with the undercarriage. When any of the undercarriages are

installed, the Idealarc DC-600 lift bail is no longer functional. Do
not attempt to lift the machine with the undercarriage attached.
The undercarriage is designed for moving the machine by hand
only. Mechanised towing can lead to injury and/or damage to the
Idealarc DC-600.
METERS
Voltmeter and ammeter are factory installed.

PARALLELING KIT FOR DC-600

Kit AT4000 - field installation only, permits paralleling of two DC-
600's for welding currents of up to 1200 amps, 100% duty cycle.
(See instructions shipped with the kit for installation and
operation.)
CONNECTIONS FOR SEMI-AUTOMATIC
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,
or connect to amphenol plug base.
4. Connect the automatic wire feeder control cable to the
amphenol/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
42/115-volt AC power to the wire feeding equipment. The circuit
has a 1000 volt ampere rating. An 8-amp slow blow fuse on the
machin300/e'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 amphenol/terminal strip as shown in Figure C.5.
4. Connect the wire feeder control cable ground lead to the
frame terminal marked (
Note: The Idealarc DC-600 must be properly grounded.
