Safety instructions for fume extraction (in accordance with DIN EN ISO 21904)

From the first time it is used, the unit contains harmful dust that can settle on surfaces and get into the ambient air. The respiratory system can be damaged if inhaled.

Check and wear your personal protective equipment.

Only use the unit in rooms which are sufficiently ventilated.

Make sure that all the seals on the unit are free of dirt.

Always only operate the unit with the designated filters.

Remove dust deposits in the surrounding area immediately using an industrial vacuum cleaner of dust class H or a damp cloth.

The extraction of substances and materials which are combustible, aggressive, chemical or contain oil vapors as well as aluminum or magnesium dusts can lead to fire and explosion due to chemical reactions. Serious injuries and irreparable damage to the unit can be the result.

Only ever use the unit as intended.

Ensure that all components have been properly installed on the fume extraction torch.

Ensure that the fume extraction torch is connected to the fume extraction system prior to use.

Use the fume extraction torch only with a fume extraction system that has been approved for use in the respective country.

Observe the local occupational health and safety regulations and guidelines.

Check the extraction hoses at regular intervals, at least once a week, for damage and contamination.

Note that the applied vacuum depends on the geographic altitude of the operation site.

Observe the warning signals and indicators on the fume extraction system. Warning signals and indicators can imply a saturated filter or a problem with/damage to the fume extraction torch.

Replace the extraction-specific wear parts at regular intervals. The replacement interval required depends on the application conditions.

Opening the air regulator is only intended to briefly reduce the volume flow at the suction nozzle. Close the air regulator immediately afterwards. The air regulator must be closed to ensure efficient capture of fumes.

Observe the instructions on the adapter label for connecting components.

When welding under particularly oily ambient conditions, creepage distances consisting of metal oxides from the welding fume can form locally on fume-carrying surfaces, which are potentially electrically conductive. Therefore, clean the welding fume-carrying surfaces on the fume extraction torch regularly.

Note that when additional exhaust air hoses or exhaust air hoses from other manufacturers are used, there can be a loss of pressure in the fume extraction torch. The components connected must be suitable for the device and guarantee the required minimum volume flow. Check the components regularly or a proper fit, leaks and blockages due to dust deposits.

Heed the requirements of DIN EN ISO 21904 as far as the minimum volume flow is concerned. If the extraction volume flow is too high, this can lead to welding faults. Check the extraction volume flow on the extraction nozzle with the aid of a suitable test rig (depending on the manufacturer).
