CONNECTION OF THE LN-25 TO THE
RANGER 305D WITH 42 VOLT REMOTEOUTPUT CONTROL MODULE(SEE FIGURE C.3.)
1. Shut the welder off.
2. Connect the electrode cable from the K626-XX
Input CableAssembly to the “-” terminal of the
welder and to the LN-25 Wire Feeder. Connect
the work cable to the “+” terminal of the welder.
NOTE: Figure C.3 shows the electrode connected for
negative polarity. To change polarity, shut the welder
off and reverse the electrode and work cables at the
Ranger 305D output terminals.
NOTE: Welding cable must be sized for current and
duty cycle of application.
3. Connect the input cable from the K626-XX Input
Cable Assembly to the 14-pin amphenol on the
Ranger 305D and the input cable plug on the LN-
25.
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 “AUTO” or “HIGH”
position as desired.
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 wire feed speed and voltage at the LN-25.
9. Set theARC control to “0” initially and adjust to
suit.
