CONNECTION OF THE LN-7 TO THE RANGER 10-LX USING K867 UNIVERSAL ADAPTER (SEE FIGURE C.4.)

1.Shut the welder off.

2.Connect the electrode cable from the LN-7 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 and duty cycle of application.

3.Connect the K867 Universal Adapter to the LN-7 wire feeder and the 14 pin amphenol of the RANGER 10-LX as indicated in Figure C.4. Make the proper connections for local or remote control according Figure C.4 and the following NOTES, indicated on the figure.

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.

CAUTION

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.

7.Place the WIRE FEEDER switch in the “WITH CON- TROL CABLE” position.

8.Adjust wire feed speed at the LN-7 and set the welding voltage with the output “CONTROL” to a CV (constant voltage) position at the welder.

NOTE: If optional remote control is used, place the output control switch in the “CONTROL REMOTE” position.
