Protecting your- When welding, you expose yourself to numerous dangers. In addition to these operating
self and others instructions, the safety rules of the manufacturer of the entire welding system must also be
observed.
Keep all persons, especially children, out of the working area while any devices are in op-
eration or welding is in progress. If, however, there are people in the vicinity,

EMC measures

In certain cases, even though a device complies with the standard limit values for emis-
sions, it may affect the application area for which it was designed (e.g. when there is sen-
sitive equipment at the same location, or if the site where the device is installed is close to
either radio or television receivers).
If this is the case, then the operator is obliged to take appropriate action to rectify the situ-
ation.
Check for possible problems, and check and evaluate neighbouring devices' resistance to
interference according to national and international requirements:

Ensure that all covers are closed and fitted properly
Keep all covers closed
make them aware of all the dangers and health risks (crushing from mechanically-
powered parts, injury from cleaning cutter / cleaning brush, flying shavings and similar
matter, escaping compressed air/parting agent mixture, flying sparks, dazzling by arc,
inhaling of harmful welding fumes, noise, possible danger from mains or welding cur-
rent, etc),
provide suitable protective equipment or
erect suitable safety screens/curtains.
Are only designed for use in industrial settings
Can cause line-bound and radiated interference in other areas
Satisfy the emissions criteria for residential and industrial areas. This is also true for
residential areas in which the energy is supplied from the public low-voltage mains.
Safety devices
Power, signal and data transfer lines
IT and telecommunications devices
Measuring and calibrating devices
Mains supply
- If electromagnetic interference arises despite correct mains connection, addition-
al measures are necessary (e.g. use a suitable line filter).
Control lines
- must be kept as short as possible
- must run close together (to avoid EMF problems)
- must be kept well apart from other leads
Equipotential bonding
Shield, if necessary
- Shield off other nearby devices
- Shield off entire welding installation
