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.

CONNECTION OF THE RANGER 10-LX TO
WIRE FEEDERS USING K867 UNIVERSAL
ADAPTER (SEE FIGURE C.1)
NOTE: When you use the RANGER 10-LX with
non-Lincoln Electric wire feeders or with
certain earlier models of Lincoln wire feed-
ers, 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 10-LX 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
10-LX. 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 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.
