7.9 Welding voltage/current monitor
In case of using welding voltage/current monitor function,
use the provided welding voltage/current monitor terminals.
Connecting to the monitor terminals
(1) Remove the terminal cover at the lower part of the con-
troller front panel.
(2) The monitor terminal is located on the left side of the
output terminal.
