CONNECTION OF THE LN-8 TO THE
RANGER 250 USING K595 CONTROL
CABLE (SEE FIGURE C.6.)
NOTE: If your LN-8 comes equipped with a K291 or
K404 input cable, refer to CONNECTION OF THE LN-
7 Using K867 UNIVERSAL ADAPTER, rather than this
discussion, to connect your Ranger 250 for wire feed
welding.
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 “-” terminal of the welder.
NOTE: Welding cable must be sized for current and
duty cycle of application.
NOTE: Figure C.6 shows the electrode connected for
positive polarity. To change polarity, shut the welder off
and reverse the electrode and work cables at the
Ranger 250 output terminals.
3. Connect the K595-XX Control Cable to the LN-8.
4. Connect the K595-XX to the 14-pin amphenol on
the Ranger 250.
5. Place the IDLER switch in the “HIGH” position.
An 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 spec-
ifications listed in this manual.
6. Set the “VOLTMETER” switch to “+” or “-” depend-
ing on the polarity chosen.
7. Set the “MODE” switch to “CV-WIRE.”
8. Set the “WELD TERMINALS” switch to “WELD
TERMINALS REMOTELY CONTROLLED.”
9. Adjust wire feed speed and voltage at the LN-8.
10. Adjust the “ARC” control to “0” initially and adjust
to suit.
