摘要： A dust collector that collects welding fumes includes: a tank that stores water in a non-full state; a first tower that stands upright from an upper surface of the tank, and is configured to receive air containing the welding fumes from an upper part of the first tower and to guide the air to the tank; a second tower that stands upright from the upper surface of the tank, and is configured such that air discharged from the tank passes through the second tower; a bottleneck structure portion in which a vertically intermediate part of the first tower is narrowed; a mist generator configured to generate mist in the first tower; and a filter housed in the second tower.
