The device generates a maximum sound power level of <80 dB(A) (ref. 1pW)
when idling and in the cooling phase following operation at the maximum per-
missible operating point under maximum rated load conditions according to
EN 60974-1.
It is not possible to provide a workplace-related emission value during welding
(or cutting) as this is influenced by both the process and the environment. All
manner of different welding parameters come into play, including the welding
process (MIG/MAG, TIG welding), the type of power selected (DC or AC), the
power range, the type of weld metal, the resonance characteristics of the
workpiece, the workplace environment, etc.
The fumes produced during welding contain harmful gases and vapours.
Welding fumes contain substances that may, under certain circumstances,
cause birth defects or cancer.
Keep your face away from welding fumes and gases.
Fumes and hazardous gases
- must not be breathed in
- must be extracted from the working area using appropriate methods.
Ensure an adequate supply of fresh air.
Otherwise, a protective mask with an air supply must be worn.
Close the shielding gas cylinder valve or main gas supply if no welding is tak-
ing place.
If there is any doubt about whether the extraction system is powerful enough,
then the measured toxic emission values should be compared with the permis-
sible limit values.
The following components are responsible, amongst other things, for the de-
gree of toxicity of welding fumes:
- Metals used for the workpiece
- Electrodes
- Coatings
- Cleaners, degreasers, etc.
The relevant material safety data sheets and manufacturer's specifications for
the listed components should therefore be studied carefully.
Flammable vapours (e.g. solvent fumes) should be kept away from the arc's
radiation area.
Flying sparks may cause fires or explosions.
Never weld close to flammable materials.
Flammable materials must be at least 11 metres (36 ft. 1.07 in.) away from the
arc, or alternatively covered with an approved cover.
A suitable, tested fire extinguisher must be available and ready for use.
Sparks and pieces of hot metal may also get into adjacent areas through small
gaps or openings. Take appropriate precautions to prevent any danger of in-
jury or fire.
