Labelling on the
product
W3 sticker
3.3 Intended use
The product is designed to extract and filter out the welding fumes
produced when welding metallic materials at the point of origin. In
general, the product can be used for all work processes in which welding
fumes are released. However, care must be taken that no glowing sparks
are drawn into the product.
Dimensions and further product details that must be observed can be
found in the technical data.
NOTE
Only products labelled with the W3 sticker have been tested and certified
accordingly. See also chapter Technical data: Welding fume class and
test standard.
NOTE
When welding alloyed or high-alloy steels with filler metals above 5%
chromium/nickel, carcinogenic CMR substances (carcinogenic,
mutagenic, reprotoxic) are released. In accordance with official
regulations, only tested and approved products may be operated in
Germany to extract these harmful smoke particles using the so-called
recirculation method.
Only products that meet the requirements of welding fume separation
class W3/IFA certified may be operated for the aforementioned welding
processes using the recirculation method.
When extracting welding fumes with carcinogenic components (e.g.
chromates, nickel oxides, etc.), the requirements of TRGS 560 (technical
rules for HAZMAT) and TRGS 528 (welding work) must be obeyed.
