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, use or service this equipment.

3.Connect the K867 Universal Adapter to the 14-pin amphenol of the Ranger 250 as shown in Figure C.1. Make the proper connections for local or remote control according to Figure C.1 and the fol- lowing NOTES, indicated on the figure:

A.These leads are not used for the Ranger 250. 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.

CONNECTION OF THE RANGER 250 TO WIRE FEEDERS USING K867 UNIVERSAL ADAPTER (SEE FIGURE C.1)

NOTE: When you use the Ranger 250 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 con- nection 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.

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- cuits may be damaged. The engine governor setting is preset at the factory – do not adjust above RPM spec- ifications listed in this manual.

6.Set the “VOLTMETER” switch to “+” or “-” depend- ing 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.
