CONNECTION OF THE LN-25 TO THE COMMANDER 400 “ACROSS THE ARC” (SEE FIGURE C.6.)

1.Shut the welder off.

2.Connect the electrode cable from the LN-25 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.6 shows the electrode connected for negative polarity. To change polarity, shut the welder off and reverse the electrode and work cables at the Commander 400 output terminals. Reverse the LN-25 polarity switch.

3.Attach the single lead from the LN-25 control box to the work using the spring clip on the end of the lead. This is only a control lead — it carries no welding current.

4.Place the IDLER switch in the “AUTO” position.

CAUTION

If you are using an LN-25 without an internal contac- tor, the electrode will be “HOT” when the Commander 400 is started.

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

6.Set the WELDING TERMINALS switch to ‘WELD-

ING TERMINALS ALWAYS ON.”

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

8.Adjust wire feed speed at the LN-25.

9.Set the LOCAL/REMOTE switch to “REMOTE” if a K444-1 remote control is used.

CAUTION

Electrode is always “HOT.”
