CONNECTION OF THE LN-7 TO THE
COMMANDER 500 USING K867
UNIVERSAL ADAPTER (SEE FIGURE C.1.)

Shut the welder off.

Connect the electrode cable from the LN-7 to the
“+” terminal of the welder. Connect the work cable
to the “-” terminal of the welder.

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

NOTE: Figure C.1 shows the electrode connected for
positive polarity. To change polarity, shut the welder off
and reverse the electrode and work cables at the
Commander 500 output terminals.

Connect the K867 Universal Adapter to the K291 or
K404 input cable and the 14-pin amphenol of the
Commander 500 as indicated in Figure C.1. Make
the proper connections for local or remote control
according to Figure C.1.

Connect the K291 or K404 input cable to the LN-7.

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 cir-
cuits may be damaged. The engine governor setting is
preset at the factory—do not adjust above RPM speci-
fications listed in this manual.

Set the VOLTMETER switch to “+” or “-” depend-
ing on the polarity chosen.

Set the OUTPUT RANGE switch to WIRE WELD-
ING CV.

Set the WELDING TERMINALS switch to WELD-
ING TERMINAL REMOTELY CONTROLLED.

Adjust wire feed speed at the LN-7.
