CONNECTION OF THE LN-7 TO THE

SA-250 WITH K623-1 WIRE FEED MODULE USING K584 INPUT CABLE ASSEMBLY (SEE FIGURE C.2.)

1.Shut the welder off.

2.Connect the electrode cable from the LN-7 to the “+” terminal of the welder. Connect the work cable to the “CV-” terminal of the welder.

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

NOTE: Figure C.2 shows the electrode connected for positive polarity. To change polarity, shut the welder off and reverse the electrode and work cables at the SA-250 output terminals.

3.Connect the input cable from the K584-XX Input Cable Assembly to the 14 pin amphenol on the K864 adapter and the input cable plug on the LN- 7.

4.Connect the K864 adapter to the 14 pin amphenol on the SA-250.

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. Adjust wire feed speed at the LN-7.

NOTE: For remote control, a K857 control is required. Connect it to the K864 adapter.

CAUTION

When the welder is in local control, the electrode is always “HOT.”
