When welding metals, there are a number of emissions which, on the one hand, cause the legally prescribed MAK values (“maximale Arbeitsplatz-Konzentration”: maximum workplace concentration) to rise above the permissible threshold value and, due to toxic and / or disease-causing ingredients, represent a health risk for the personnel in the processing area. This fact obliges companies in the welding industry in particular to ensure effective air filtering and ventilation in the areas concerned. Because not only the welder himself is affected by the harmful emissions, but also the rest of the staff in the production hall, who are exposed to the welding fumes.
In addition to a large number of stationary fume extraction systems, the torch-integrated fume extraction (fume extraction torches) is one of the most effective and mobile methods that can be used. Welding with fume extraction torches is definitely a challenge when it comes to the handling.
So how can you weld correctly with fume extraction torches? What do you need to pay attention to?
