Wiring to wire feeder
This section explains how to connect the voltage detection cable at the base metal side to the wire feeder.
1.
Check that input power is turned off with the disconnect switch connected to the welding power source.
2.
Remove the right side panel of the wire feeder.
3.
Connect the voltage detection cable at the base metal side to the terminal board in the wire feeder (wire No.
310).
●
Use the voltage detection cable at the base metal side via the blind bush with film.
4.
Restore the right side panel of the wire feeder.
Wiring of voltage detection cable is complete.
