WARNING!
The fumes given off during welding
contain gases and vapours that are
harmful to health.
This can result in serious injury.
▶
It is not permissible to carry out
welding if the extractor unit is not
switched on.
In situations where it is not possible to
get down to - or below - the MWC
(max. workplace concentration) values,
an extra fume-extractor system must
be installed.
Guideline values for fume extraction
units:
- Extraction capacity: 50-100 m³/h
- Negative pressure: 5,000-20,000
