CONNECTION OF THE LN-25 TO THE
V350-PRO "ACROSS THE ARC" WITH
OPTIONAL 6 PIN K857 REMOTE CON-
TROL.
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. Connect the K857 remote control to the 6-pin
amphenol on the V350-PRO.
4. 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.
