PAPR welding helmet Dräger X-Plore 8000
The Dräger X-plore 8000 PAPR welding helmet is particularly suitable for long welding periods, providing both respiratory protection against particles and smoke emissions and eye protection against welding arcs.
The visor of this welding powered air purifying helmet is equipped with an automatic welding filter ADF 9-13 covering most of the welder's safety requirements. It is suitable for all welding types like arc welding (especially low amperage TIG), plasma (welding and cutting), tacking and grinding. Detailed description
Toxicity of welding fumes
Welding fumes are Group 2B classified "possible carcinogens" by the International Agency for Research on Cancer (IARC). The carcinogenic agents involved are not fully identified given the number and diversity of compounds present in welding fumes.
The chemical composition of welding fumes depends on the nature of the base metal and the surface coating, as well as the used process used, including the filler metal and the used wires or electrodes. The main metal fumes or dust involved are chromium oxides, iron, nickel and cadmium. Presence of grease or paint on the metal to be welded generates carcinogenic decomposition products, such as formalin or certain polycyclic aromatic hydrocarbons (PAHs).
The welding helmet with powered air
In welding facilities local exhaust ventilation techniques should be used. Failing this and / or in addition, a personal protective device is strongly recommended such as the use of a PAPR welding helmet (particularly comfortable solution and suitable for long duration work) with a specific hood.
A powered air purifying respirator's motor draws ambient air through filters and propels it into the head protector (welding helmet) via a corrugated hose. The PAPR device decreases the breathing effort and thus reduces fatigue generated by using a conventional air purifying respirator such as a gas mask. It is a respiratory system particularly suitable for long, strenuous and regular work and / or in case of high temperatures. The overpressure generated in the PAPR welding helmet guarantees a high Nominal Protection Factor.
What type of welding filters?
Two types of respiratory protection filters can be fitted to a PAPR welding helmet:
P3 filters (or PSL for solid and liquid particles), able to filter 99.97% of dust and metal particles such as oxides of chromium, iron, nickel and cadmium)
A2-P3 combined filters, strongly recommended in case of grease or paints presence on the metal to be welded. Indeed, brought to high temperatures, paints, greases and varnishes on the parts to be welded give off toxic fumes and vapors such as formalin or certain polycyclic aromatic hydrocarbons (PAHs).
