Question

Quizplus · Accepted Answer

A smoke extraction nozzle can help control fumes by capturing the smoke and directing it away from the welder's face. A filter screen or small fan may help to some extent, but may not be as effective in removing the fumes from the welding area. A dust mask is not sufficient for controlling fumes as it only protects the welder's respiratory system and does not remove the fumes from the surrounding area.
