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.

Mobile extraction units for professional welders: 8 criteria that define good entry-level models

For many welders, the price also counts when buying a mobile extraction unit. However, even inexpensive entry-level units provide effective protection for industrial welding applications. At comparable entry-level prices, even the basic equipment differs greatly in some cases. What mobile extraction units are capable of today.
