How to ensure effective at-source welding fume extraction using extraction arms for local exhaust ventilation
Placing an extraction arm in the right spot sounds simple, but it's one of the most common ways welding fume control falls short in practice. Even quality equipment underperforms if it's positioned too far from the arc, angled wrong, or too cumbersome for welders to adjust between passes. This piece breaks down what actually determines capture efficiency at the source, and when at-source extraction needs to be paired with other ventilation strategies to fully protect your team.
This guide from Nederman covers how extraction arms capture welding fumes at the source, why positioning (not just equipment choice) drives performance, and where at-source extraction alone falls short in high-volume or multi-process shops. Read the full article on Nederman's Knowledge Center.
