5.9.1 Automation interface
WARNING
No function of the external interrupt equipment (emergency stop switch)!
If the emergency stop circuit has been set up using an external interrupt equipment
connected to the interface for automated welding, the machine must be configured for
this setup. If this is not observed, the power source will ignore the external interrupt
equipment and will not shut down!
• Remove jumper 1 on the corresponding control board (to be done only by qualified service
personnel)!

The operating mode is specified by the wire feeder (the start / stop function corresponds to the opera-
tion of the torch trigger and is used, for instance, in mechanized applications).
