Abstract: An electrostatic coating apparatus includes: a spray gun configured to spray a coating material onto a coating object; a voltage application device configured to apply a high voltage to the spray gun; and a current measurement device configured to measure electric current flowing through the spray gun. When the spray gun, which is in a state of not spraying the coating material onto the coating object and is under application of the high voltage from the voltage application device, is located at a distance from the coating object, the electric current flowing through the spray gun is measured by the current measurement device. A grounded state of the coating object is checked, based on the measured electric current. This shortens the time required for checking the grounded state, while allowing for downsizing and simplified configuration of production equipment and reduction of equipment cost.

Abstract: 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.
