CONNECTION OF THE LN-8 TO THE
COMMANDER 300 USING K867
UNIVERSAL ADAPTER (SEE FIGURE C.3.)
1. Shut the welder off.
2. Connect the electrode cable from the LN-8 to the
“+” terminal of the welder. Connect the work cable
to the “CV- Wire” 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
Commander 300 output terminals.
3. Connect the K867 Universal Adapter to the K196
input cable and the 14-pin amphenol of the
Commander 300 as indicated in Figure C.3. Make
the proper connections for local or remote control
according to Figure C.3.
4. Connect the K196 input cable to the LN-8.
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. Set the LOCAL/REMOTE switch to “REMOTE.”
7. Set the VOLTMETER switch to “+” or “-” depend-
ing on the polarity chosen.
8. Set the OUTPUT RANGE switch to “WIRE
WELDING CV.”
9. Set the WELDING TERMINALS switch to
“WELDING TERMINALS REMOTELY CON-
TROLLED.”
10. Adjust wire feed speed and voltage at the LN-8.
11. Adjust the ARC CONTROL to the desired level
(“soft” or “crisp”).
