Interfaces for automation
WARNING
Do not carry out any unauthorised repairs or modifications!
To avoid injury and equipment damage, the unit must only be repaired or modified by
specialist, skilled persons!
The warranty becomes null and void in the event of unauthorised interference.
• Appoint only skilled persons for repair work (trained service personnel)!
Unsuitable control cables or incorrect input/output signal assignment can cause damage to the
machine. Use shielded control cables only.
5.6.1
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)!
These accessory components can be retrofitted as an option

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