CONNECTION OF THE LN-7 TO THE
CLASSIC III OR CLASSIC IIID (EQUIPPED
WITH K623-1 WIRE FEED MODULE)
USING K584 INPUT CABLE ASSEMBLY
(SEE FIGURE C.2.)

1. Shut the welder off.

2. Connect the electrode cable from the LN-7 to the

“+” terminal of the welder. Connect the work cable
to the “CV-” terminal of the welder.

NOTE: Welding cable must be sized for current and
duty cycle of application.

NOTE: Figure C.2 shows the electrode connected for
positive polarity. To change polarity, shut the welder
off and reverse the electrode and work cables at the

Classic III or Classic IIID

output terminals.

3. Connect the input cable from the K584-XX Input

Cable Assembly to the 14 pin amphenol on the
K864 adapter and the input cable plug on the LN-
7.

4. Connect the K864 adapter to the 14 pin amphenol

on the

Classic III or Classic IIID

5. Place the IDLER switch in the “HIGH” position.

Any increase of the high idle engine RPM by changing
the governor setting or overriding the throttle linkage
will cause an increase in the AC auxiliary voltage. If
this voltage goes over 140 volts, wire feeder control
circuits may be damaged. The engine governor set-
ting is preset at the factory — do not adjust above
RPM specifications listed in this manual.

6. Adjust wire feed speed at the LN-7.

NOTE: For remote control, a K857 control is required.
Connect it to the K864 adapter.

When the welder is in local control, the electrode is
always “HOT.”
