4. Connect the wire feeder control cable ground lead
to the frame terminal marked (
NOTE: The IDEALARC DC-600 must be properly
grounded.
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. Tape the bolted connec-
tion 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
connected directly to the DC-600 terminal
