CONNECTION OF THE LN-7 TO THE

RANGER 305D USING K584 CONTROL

CABLE

(SEE FIGURE C.5.)

NOTE: If your LN-7 comes equipped with a K291 or
K404 input cable, refer to CONNECTIONS OF THE
LN-7 Using K867 UNIVERSALADAPTER, rather than
this discussion, to connect your Ranger 305D for wire
feed welding.
1. Shut the welder off.
2. Connect the electrode cable from the K584-XX
Control Cable to the “+” terminal of the welder and
to the LN-7 wire feeder. Connect the work cable
to the “-” terminal of the welder.
NOTE: Figure C.5 shows the electrode connected for
positive polarity. To change polarity, shut the welder
off and reverse the electrode and work cables at the
output terminals.
NOTE: Welding cable must be sized for current and
duty cycle of application.
3. Connect the input cable from the K584-XX Control
Cable to the 14-pin amphenol on the Ranger 305D
and the input cable plug on the LN-7.
4. Set the “VOLTMETER”switch to “+” or “-” depend-
ing on the polarity chosen.
5. Set the “MODE” switch to the “CV-WIRE” position.
6. Place the “IDLER” switch in the “HIGH” position.
Any increase of the high idle engine RPMby changing
the governor setting or overriding the throttle linkage
will cause an increase in the AC auxiliary voltage. If
thisvoltage goes over 140 volts, wire feeder control cir-
cuit may be damaged. The engine governor setting is
preset at the factory - do not adjust above RPM speci-
fications listed in this manual.
------------------------------------------------------------------------
7. Place the “WELD TERMINALS” switch in the
“REMOTELYCONTROLLED” position.
8. Adjust the wire feed speed at the LN-7 and adjust
the welding voltage with the optional remote con-
trol is used.
9. Set theARC control to “0” initially and adjust to
suit.
