CONNECTION OF THE LN-25 WITH K431 REMOTE OPTION TO THE V350-PRO.

NOTE: AN LN-25 CAN ONLY BE USED WITH A FAC- TORY OR “CE” VERSION OF THE V350-PRO.

1.Remove input power to the V350-PRO.

2.Connect the electrode cable to the output terminal of polarity required by the electrode. Connect the work lead to the other terminal. Welding cable must be sized for current and duty cycle of the application.

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.Set the voltmeter switch to the electrode polarity chosen.

6.Set the “MODE” to the “CV-WIRE” position.

7.Set “WELD TERMINALS SELECT” to the “REMOTE” position.

8.Set the “ARC CONTROL” to the “O” position and then adjust to suit.
