Abstract: The present disclosure provides a head-mounted welding mask, which includes a mask shell, a head-mounted mechanism, and a flip device, the flip device includes a knob which is connected to the mask shell, a link mechanism which is connected to the knob, and a base which is connected to the head-mounted mechanism, the link mechanism is disposed on the base, when the knob is moved, the knob drives the link mechanism to reciprocate in an arc, so that the mask shell flips relative to the head-mounted mechanism, and the barycenter of the mask shell moves into a predetermined range that is determined based on the gravity line where the barycenter of the head-mounted mechanism is located. The flip device changes the position of the barycenter of the mask shell through the movement of the link mechanism, so that the barycenter of the mask shell moves into a predetermined range that is determined based on the gravity line where the barycenter of the head-mounted mechanism is located.
