CONNECTION OF THE LN-25 TO THE
CLASSIC II USING K867 UNIVERSAL
ADAPTER (SEE FIGURE C.3.)

1. Shut the welder off.

2. Connect the electrode cable from the LN-25 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.3 shows the electrode connected for

positive polarity. To change polarity, shut the
welder off and reverse the electrode and work
cables at the Classic II output terminals.
Reverse the LN-25 polarity switch.

3. Connect the K867 Universal adapter to the K432-L

cable and the 14 pin amphenol of the Classic II as
indicated in Figure C.3.

4. Connect the K433 to the LN-25. Mount the K433

to the welder according to instructions included
with the K433 kit.

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 and voltage at the LN-25.
