W3: That is why the IFA certificate is more a seal of quality than a pure test seal
A W3 certificate: This is what most manufacturers of welding fume extraction units want. Because behind this is a test mark that is only awarded to units that meet the highest requirements. In Germany, it is mandatory for some welding work. Internationally, it is now considered an important mark of quality. About the history and significance of one of the most important test marks for welders.
The optimum exhaust hood for optimum collection
Extraction systems should making working on pieces easier for welders. A correctly designed exhaust hood helps effectively secure occupational safety. The best extraction performance and the best filter technology are useless if the welding fumes do not find their way … >> more
Collect and separate: how to achieve effective occupational safety
Extraction and filter technology is fundamental to effective occupational safety. But the behavior of the welder is also significant. Thus collection efficiency is not the same as filtration efficiency. What good does it do occupational safety to use the best … >> more
