CONNECTION OF THE LN-23P TO THE
CLASSIC III OR CLASSIC IIID

(EQUIPPED

WITH K623-1 WIRE FEED MODULE)

USING

THE K-350-1 ADAPTER KIT (SEE FIGURE
C.5)

1. Shut the welder off.

2. Connect the electrode cable from the LN-23P to the

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

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

3. Mount the K350-1 adapter per instructions included

with the adapter.

4. Connect the LN-23P to the K350-1 adapter as indi-

cated in Figure C.5. The adapter allows two wire
feeders to be connected. If only one is used, con-
nect it to Feeder “A” terminal strip.

5. Connect the adapter cable from the K350-1 to the

14-pin amphenol on the Classic III or Classic IIID
wire feed module.

The output terminals are energized when the engine is
running. The CV output will be de-energized only if
WFM mode switch is in remote position.

6. Connect control lead marked “21” to the work as

indicated in Figure C.5.

7. Set the CURRENT RANGE SELECTOR switch to

the 190-120 (middle) position for most common
processes. This may be changed if a different arc
characteristic is preferred.

8. Set the LOCAL/REMOTE control toggle switch to

REMOTE.

9. Set the IDLER switch to the AUTO position. The

HIGH position may be required when welding with
low current processes.

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 specification listed in the manual.
