Meandering weld-
ing flows
EMC measures
Arrange for the mains and device supply to be checked regularly by a qualified
electrician to ensure the PE conductor is functioning properly.
The device must only be operated on a mains supply with a PE conductor and
a socket with an earth contact.
If the device is operated on a mains without a PE conductor and in a socket
without an earth contact, this will be deemed gross negligence. The manufac-
turer shall not be liable for any damage resulting from such improper use.
If necessary, provide an adequate earth connection for the workpiece.
Switch off unused devices.
Before working on the device, switch it off and pull out the mains plug.
Attach a clearly legible and easy-to-understand warning sign to the device to
prevent anyone from plugging the mains plug back in and switching it on
again.
After opening the device:
-
discharge all live components
- ensure that all components in the device are de-energised
If work on live parts is required, appoint a second person to switch off the main
switch at the right moment.
If the following instructions are ignored, meandering welding flows can devel-
op with the following consequences:
-
Fire hazard
- Overheating of parts connected to the workpiece
- Irreparable damage to PE conductors
- Damage to device and other electrical equipment
Warning, electromagnetic field Electromagnetic fields may pose as yet un-
known risks to health.
It is the operator's responsibility to ensure that no electromagnetic interference
occurs in electrical and electronic devices.
If electromagnetic interference is detected, the operator is obliged to take ac-
tion to rectify the situation.
Check for possible problems, and check and evaluate neighbouring devices'
resistance to interference according to national and international require-
ments:
-
Safety features
- power, signal and data transfer lines
- IT and telecommunications devices
- measuring and calibrating devices
- the health of neighbouring persons
