(for example in residential areas) may disturb other electric
devices.
 During welding electromagnetic problems can be caused
at:
– Mainscables, controlcables, connections for telecom-
munication
– TV/Radio
– Computer and other similar devices
– Protection devises as for example alarm systems
– Pacemakers and hearing aids
– Devices for measure and calibrate
– Devices with less protection against disturbances
If other devices are disturbed it may be necessary to pro-
tect additionally.
 The affected area can be bigger than your premises/pro-
