EMC precautions
Particular danger
spots
It is the responsibility of the owner/operator to ensure that no
electromagnetic interference is caused to electrical and electronic
equipment.
If electromagnetic interference is found to be occurring, the owner/operator
is obliged to take all necessary measures to prevent this interference.
Examine and evaluate any possible electromagnetic problems that may
occur on equipment in the vicinity, and the degree of immunity of this
equipment, in accordance with national and international regulations:
- safety features
- mains, signal and data-transmission leads
- IT and telecoms equipment
- measurement and calibration devices
- the health of persons in the vicinity, e.g. users of heart pacemakers and
hearing aids
- users of heart pacemakers must take medical advice before going
anywhere near welding equipment or welding workplaces
Electromagnetic fields may cause as yet unknown damage to health.
Ancillary measures for preventing EMC problems:
a) Mains supply
- If electromagnetic interference still occurs, despite the fact that the
mains connection is in accordance with the regulations, take additional
measures (e.g. use a suitable mains filter).
b) Welding cables
- Keep these as short as possible
- Arrange them so that they run close together
- Lay them well away from other leads.
c) Equipotential bonding
d) Workpiece grounding (earthing)
- where necessary, run the connection to ground (earth) via suitable
capacitors.
e) Shielding, where necessary
- Shield other equipment in the vicinity
- Shield the entire welding installation.
Keep your hands, hair, clothing and tools well away from all moving parts,
e.g.:
- fans
- toothed wheels
- rollers
- shafts
- wire-spools and welding wires
Do not put your fingers anywhere near the rotating toothed wheels of the
wirefeed drive (MIG/MAG power sources).
Covers and sideguards may only be opened or removed for as long as is
absolutely necessary to carry out maintenance and repair work.
