MULTI-PROCESS SWITCH

The MULTI-PROCESS SWITCH gives you the ability
to:
• Switch between "stick welding or air/carbon arc
cutting" and using a semi-automatic or automatic
wire feeder.
• Change the polarity of a semi-automatic or auto-
matic wire feeder without changing any electrical
cable connections.

The MULTI-PROCESS SWITCH has two sets of output
terminals. You connect the wire feeder unit cables to
the set of terminals on the left side of the box and the
stick or air/carbon arc cables to the set of terminals on
the right side (facing the front of the machine) as
shown in Figure C.1.
When the MULTI-PROCESS SWITCH is in the "Stick
or Air/Carbon Arc"
terminals are energized. The wire feeder nozzle or
gun and electrode are not electrically "hot" when in this
mode.
Follow these steps to install the MULTI-PROCESS
SWITCH:
1. Confirm that the IDEALARC DC-600 ON/OFF
PUSH BUTTON is in the OFF position.
2. Disconnect main AC input power to the IDE-
ALARC DC-600.
3. Open the terminal strip access door located on the
Case Front Assembly.
4. Remove the two front, middle screws that secure
the two side panels of the machine. See Figure
C.2.
