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.

CAUTION

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

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 UNIVERSAL ADAPTER, 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.
