During operation
- Ensure that all covers are closed and fitted properly
- Keep all covers closed
Protecting your-
self and others
Anyone working with the device exposes themselves to numerous risks. In addition to
these Operating Instructions, the safety rules of the manufacturer of the entire welding sys-
tem 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:
- Make them aware of all the dangers and health risks (crushing from mechanically-
powered parts, injury from cleaning cutter, flying shavings and similar matter, escap-
ing compressed air/parting agent mixture, flying sparks, dazzling by arc, inhaling of
harmful welding fumes, noise, possible danger from mains or welding current, etc.)
- Provide suitable protective equipment
- Alternatively, erect suitable safety screens/curtains
EMC Device Clas-
sifications
Devices in emission class A:
- Are only designed for use in industrial settings
- Can cause line-bound and radiated interference in other areas
Devices in emission class B:
- 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.
EMC device classification as per the rating plate or technical data.
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:
- Safety devices
- Power, signal and data transfer lines
- IT and telecommunications devices
- Measuring and calibrating devices
Supporting measures for avoidance of EMC problems:
1. Mains supply
- If electromagnetic interference arises despite correct mains connection, addition-
al measures are necessary (e.g. use a suitable line filter).
2. 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
3. Equipotential bonding
4. Shield, if necessary
- Shield off other nearby devices
- Shield off entire welding installation
