NOTE: AN LN-7 CAN ONLY BE USED WITH A FAC- TORY OR “CE” VERSION OF THE V350-PRO. IF YOUR LN-7 COMES EQUIPPED WITH A K291 OR K404 INPUT CABLE, REFER TO THE CONNECTION OF THE LN-7 USING K867 UNIVERSAL ADAPTER.

1.Remove input power to the V350-PRO.

2.Connect the electrode cable from the K480 control cable to the “+” terminal of the welder and to the LN-7 wire feeder. Connect the work cable to the “-” terminal of the welder.

NOTE: Figure C.5 shows the electrode connected for positive polarity. To change polarity, shut the welder off and reverse the electrode and work cables at the output terminals.

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

3.Connect the input cable from the K480 control cable to the (115VAC) 14 pin amphenol on the V350-PRO and the input cable plug on the LN-7.

4.Set the “VOLTMETER” switch to “+” or “-” depending on the polarity chosen.

5.Set “CONTROL SELECT” to “REMOTE”.
