Danger From Flying Sparks; Dangers From Welding Current - Fronius ActiveCharger 1000 Operating Instructions Manual

Ensure an adequate supply of fresh air with a ventilation rate of at least 20 m³/hour.
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 arc's radiation area.
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 metres (36 ft. 1.07 in.) away from the arc, or al-
ternatively 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.
Dangers from
An electric shock is potentially life threatening and can be fatal.
welding current
Do not touch live parts either inside or outside the device.
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.
All cables and leads must be secured, undamaged, insulated and adequately dimen-
sioned. Loose connections, scorched, damaged or inadequately dimensioned cables and
leads must be replaced immediately.
Do not sling cables or leads around the body or parts of the body.
The electrode (rod electrode, tungsten electrode, welding wire, etc.) must
-
-
Double the open circuit voltage of a power source can occur between the welding elec-
trodes of two power sources. Touching the potentials of both electrodes at the same time
may be fatal under certain circumstances.
Metals used for the workpiece
Electrodes
Coatings
Cleaners, degreasers, etc.
never be immersed in liquid for cooling
never be touched when the power source is switched on.
