CONNECTION OF THE LN-8 TO THE COMMANDER 400 USING K595 INPUT CABLE ASSEMBLY (SEE FIGURE C.4.)

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 “CV- Wire” terminal of the welder.

NOTE: Welding cable must be sized for current and duty cycle of application.

NOTE: Figure C.4 shows the electrode connected for positive polarity. To change polarity, shut the welder off and reverse the electrode and work cables at the Commander 400 output terminals.

3.Connect the K595-XX Input Cable Assembly to the LN-8.

4.Connect the K595-XX to the 14 pin amphenol on the Commander 400.

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 LOCAL/REMOTE switch to “REMOTE.”

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

8.Set the RANGE switch to “WIRE WELDING CV.”

9.Set the WELDING TERMINALS switch to “WELD-

ING TERMINALS REMOTELY CONTROLLED.”
