1.Shut the welder off.

2.Connect the electrode cable from the LN-23P 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.5 shows the electrode connected for negative polarity.

3.Connect the K350-1 adapter to the amphenol on the LN-23P and the 14-pin amphenol of the Commander 300 as indicated in Figure C.5.

4.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.

5.Set the VOLTMETER switch to negative.

6.Set the OUTPUT RANGE switch to “WIRE WELD- ING CV.”

7.Set the WELDING TERMINALS switch to “WELD-
