1.Shut the welder off.

2.Connect the electrode cable from the LN-8 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.

NOTE: Figure C.3 shows the electrode connected for positive polarity. To change polarity, shut the welder off and reverse the electrode and work cables at the Commander 500 output terminals.

3.Connect the K867 Universal Adapter to the K196 input cable and the 14-pin amphenol of the Commander 300 as indicated in Figure C.3. Make the proper connections for local or remote control according to Figure C.3.

4.Connect the K196 input cable to the LN-8.

5.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.

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

7.Set the OUTPUT RANGE switch to WIRE WELD-
