Signal
Gives the compensation value of the arc
voltage when set to "Synergic."
(When set to "independent," the arc volt-
age is sent directly.)
Gives the set value of the output current
(wire feeding amount) for the welding
source.
Performs the wire inching.
Withdraws the wire.
Instructions to start/stop the welding.
Sends the output terminal voltage of the
welding source.
The wire stick detection voltage
(approx.15 V) is input from the robot side.
