Danger From Flying Sparks; Risks From Mains Current And Welding Current - Fronius Laser hybride Instructions De Service

Keep your face away from welding fumes and gases.
Fumes and hazardous gases
-
-
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 taking place.
If there is any doubt about whether the extraction capacity is sufficient, the measured toxic
emission values should be compared with the permissible limit values.
The following components are responsible, amongst other things, for the degree of toxicity
of welding fumes:
-
-
-
-
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 radiation area of
the laser and the arc.
Danger from fly- Flying sparks may cause fires or explosions.
ing sparks
Never weld close to flammable materials.
Flammable materials must be at least 11 m (35 ft.) away from the LaserHybrid welding pro-
cess, 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 injury or fire.
Welding must not be performed in areas that are subject to fire or explosion or near sealed
tanks, vessels or pipes unless these have been prepared in accordance with the relevant
national and international standards.
Do not carry out welding on containers that are being or have been used to store gases,
propellants, mineral oils or similar products. Residues pose an explosive hazard.
Risks from mains An electric shock is potentially life threatening and can be fatal.
current and weld-
Do not touch live parts either inside or outside the device.
ing current
During MIG/MAG welding and TIG welding, the welding wire, the wirespool, the feed rollers
and all pieces of metal that are in contact with the welding wire are live.
Always set the wirefeeder up on a sufficiently insulated surface or use a suitable, insulated
wirefeeder holder.
Make sure that you and others are protected with an adequately insulated, dry temporary
backing or cover for the earth or ground potential. This temporary backing or cover must
extend over the entire area between the body and the earth or ground potential.
must not be breathed in
must be extracted from the working area using appropriate methods.
