CONNECTING THE LN-7 WIRE FEEDER TO
THE IDEALARC DC-1000
1.
Set the IDEALARC DC-1000 ON/OFF PUSH
BUTTON to OFF.
2.
Disconnect main AC input power to the IDE-
ALARC DC-1000.
3
Connect the wire feeder control cable leads to the
IDEALARC DC-1000 terminal strip as shown in
Figure C.5.
4.
Connect the wire feeder control cable ground lead
to the frame terminal marked .
5.
PERFORM THIS STEP ONLY IF THE LN-7 IS
EQUIPPED WITH A METER KIT.
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: If the work cable length is less than 25 feet
and the connections to the work piece are secure,
then wire feeder control cable lead #21 can be con-
nected directly to the DC-1000 terminal strip.
NOTE: An S-16586-X remote voltage sensing work
lead is available for this purpose.
b.
Keep the #21 lead electrically separate
from the work cable circuit and connection.
c.
Tape the #21 lead to work cable for ease
of use.
6.
Connect the welding cables as shown in Figure
C.5.
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.5
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
POLARITY SWITCH to NEGATIVE.
