Interfaces for automation
The welding power sources feature a very high standard of safety.
This safety standard is also maintained when peripheral equipment is connected for automatic welding if
this peripheral equipment fulfils the same criteria, particularly with regard to isolation from the mains
supply.
This is ensured by the use of transformers according to VDE 0551.
The welding machines are prepared for automated operation as standard.
Use only shielded control leads.
