NOTE: The connection diagram shown in Figure C.2
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.
Refer to NA-5 operator’s manual for proper
control box polarity connections.
NOTE: For proper NA-5 operation, the electrode
cables must be secured under the clamp bar on the
left side of the NA-5 Control Box.
CONNECTING THE LN-8 TO THE
IDEALARC DC-1000
1.
Set the ON/OFF PUSH BUTTON to the OFF pos-
tion.
2.

DC-1000 terminal strip. See Figure C.3.
4.
Connect the wire feeder control cable ground lead
to the frame terminal marked .
5.
Extend the wire feeder control cable #21 lead so it
can be connected directly to the work piece.
a.
