There are many different factors that influence worker exposure to welding fumes, including the welding process used, the base and filler metals, the composition of the welding electrodes, the welding area (confined or well-ventilated), and whether the workshop uses ventilation or welding fume extraction equipment.

To minimize pollution and health impacts, many facilities have installed welding fume extractors. Among these, mobile welding fume extractors are widely used due to their advanced technology, convenience, mobility, adjustability, and ease of operation.
