(SEE FIGURE C.1)
NOTE: When you use the Ranger 305D with non-Lincoln Electric wire feeders
or with certain earlier models of Lincoln wire feeders, you will require the
K867 Universal Adapter. The following discussion and connection
diagram explain in general how to make the proper connections.
1. Shut the welder off.
2. Connect the electrode cable from the wire feeder 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.
3. Connect the K867 Universal Adapter to the 14-pin amphenol of the
Ranger 305D as shown in Figure
C.1. Make the proper
connections for local or remote
control according to Figure C.1.
and the following NOTES, indicated on the figure:
A. These leads are not used for the Ranger 305D. Insulate
each unused lead individually.
B. For wire feeders that return a signal for welding output,
use an isolation relay to close leads 2 and 4.
C. Refer to the Operation section of this manual for
maximum wire feeder auxiliary current draw.
4. Set the "MODE" switch to the "CV-WIRE" position.
5. Place the "IDLER" switch in the "AUTO" position.
C UTION
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 circuit may be damaged. The engine governor setting is
preset at the factory - do not adjust above RPM specifications listed in
this manual.
6. Set the "VOLTMETER" switch to "+" or "-" depending on the
polarity chosen.
7. Set the ARC control to "0" initially and adjust to suit.
8. Adjust wire feed speed at the wire feeder.
