♦
Never look into the LED lamp or its reflections without eye protection; always use a protective shield
or safety goggles with suitable protective glass.
Keep others, in particular children, away during operation of the devices and execution of the welding process.
However, if persons are in close proximity inform them of all dangers (risk of dazzling by arc, risk of injury due
to flying sparks, welding fumes that are harmful to health, possible dangers due to mains or welding current),
♦
make suitable means of protection available, or
♦
install protective walls and curtains.
Note that the device's raw materials that could come into contact with the operator's skin may cause allergic
reactions in susceptible people.
4.4 Danger due to harmful gases and vapours
Welding work produces fumes that contain health-endangering gases and vapours.
Welding fumes contain substances that may cause birth defects and cancer under
certain circumstances.
The fumes and harmful gases produced
♦
must not be inhaled
♦
must be extracted from the working area using suitable equipment.
Ensure a sufficient fresh air supply - air flow rate of min. 20 m³/h. With insufficient ventilation, use a
respiratory protection mask with air supply. When welding is not taking place, close the valve of the protection
gas canister or the main gas supply. If you are unsure whether the extraction capacity is sufficient, compare
the measured hazardous substance emission values with the permissible exposure limit values.
The following components all contribute to the degree of harmfulness of the welding fumes:
♦
The metals used for the workpiece
♦
Electrodes
♦
Coatings
♦
Welding wires
♦
Unsuitable cleaning substances and similar
Please consider the respective material safety data sheets and manufacturer’s instructions for the components
listed. Keep flammable vapours (e.g. solvent vapours) away from the radiation range of the arc.
4.5 Danger due to flying sparks
Flying sparks can trigger fires and explosions. Never weld in close proximity
to flammable materials. Flammable materials must be kept at least 10 metres away
from the arc, or covered with a tested and approved cover. Keep suitable, tested fire extinguishers at hand.
Sparks and hot metal parts may also penetrate neighbouring areas through small cracks and openings.
Implement appropriate measures so that no risk of injury and fire can arise. Do not weld in areas at risk of fire
or explosion, or in connected tanks, barrels or pipes, if these have not been prepared in accordance with the
respective national and international standards. It is prohibited to weld in tanks that contain or have contained
gases, fuels, mineral oils or similar. Residues pose a risk of explosion.
