Function
Supervision of gas/liquid cooling
The input is monitored during the weld start and during the welding.
An active signal indicates a satisfactory gas and liquid flow.
If the signal disappears, welding in progress is interrupted, an error
message is shown and the robot stops.
Supervision of current
The input is monitored during the weld start, during the welding and
during the filling time. An active signal indicates a satisfactory
welding current.
If the signal disappears, welding in progress is interrupted, an error
message is presented and the robot stops.
Wire feed on
The input is only activated for manual feed of a new welding wire.
Process off
The input is activated to block the welding during the test running of
the welding program. The robot then executes program without
connecting the welding instruction via outputs 7-9.
Weaving off
The input is activating for blocking a weaving motion during welding
in progress. The robot then executes the weaving instructions as
ordinary motions.
Voltage on
An active signal connects the welding equipment.
Wire feed on
An active signal connects the wire feeder.
Gas on
An active signal connects the flow of protective gas.
