CONNECTION OF LINCOLN ELECTRIC WIRE FEEDERS

WARNING
ELECTRIC SHOCK can kill.
• Do not operate with panels open.
• Disconnect NEGATIVE (-) BATTERY
LEAD before servicing.
• Do not touch electrically live parts.
MOVING PARTS can injure.
• Keep guards in place.
• Keep away from moving parts.
• Only qualified personnel should install,

CONNECTION OF THE RANGER 9 TO
WIRE FEEDERS USING K867 UNIVERSAL
ADAPTER (SEE FIGURE C.1)
NOTE: When you use the RANGER 9 with non-
Lincoln Electric wire feeders or with cer-
tain earlier models of Lincoln wire feeders,
you will require the K867 Univeral 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 "ELECTRODE" terminal of the welder. Connect
the work cable to the "TO WORK" terminal of the
welder.

NOTE: Welding cable must be sized for current
3. Connect the K867 Universal Adapter to the 14 pin
amphenol of the RANGER 9 as shown in Figure F.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 9.
Insulate each unused lead individually.
B. For wire feeders that return a signal for weld-
ing output, use an isolation relay to close leads
2 and 4.
C. Refer to the OPER-
ATION section of this manual for maximum
auxiliary current draw.
4. Set the welder "polarity" switch to the desired
polarity, either DC (-) or DC (+).
5. Set the "RANGE" switch to the "WIRE FEED" posi-
tion.
6. Place the "IDLER" switch in the "HIGH" position.
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
circuits may be damaged. The engine governor set-
ting is preset at the factory — do not adjust above
RPM specifications listed in this manual.
