EMF measures
Safety measures
at the installation
location and dur-
ing transport
Supporting measures for avoidance of EMC problems:
1. Mains supply
- If electromagnetic interference arises despite correct mains connec-
tion, additional measures are necessary (e.g. use a suitable line fil-
ter).
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
Electromagnetic fields may pose as yet unknown risks to health:
- effects on the health of others in the vicinity, e.g. wearers of pacemakers
and hearing aids
- wearers of pacemakers must seek advice from their doctor before ap-
proaching the device or any welding that is in progress
- for safety reasons, keep distances between the welding cables and the
welder's head/torso as large as possible
- do not carry welding cables and hosepacks over the shoulders or wind
them around any part of the body
A device toppling over could easily kill someone. Place the device horizontally
on a level, firm and solid surface and anchor it securely to prevent it toppling
over.
Special regulations apply in rooms at risk of fire or explosion
- Observe relevant national and international regulations.
Use internal directives and checks to ensure that the workplace environment
is always clean and clearly laid out.
When transporting the device, observe the relevant national and local guide-
lines and accident prevention regulations. This applies especially to guidelines
regarding the risks arising during transport.
After transporting the device, it must be visually inspected for damage before
commissioning. Any damage must be repaired by trained service technicians
before commissioning the device.
