The present application relates to a welding apparatus and an auto-darkening welding helmet (1) therefor. The auto-darkening welding helmet (1) comprises a helmet casing (10); an auto-darkening filter (20) secured on the helmet casing (10); a wireless communication module (100b) and a control circuit (700) which are installed on and/in the helmet casing (10), wherein the wireless communication module (100b) is able to be in wireless data communication with an external apparatus, and based on data received from the external apparatus, the control circuit (700) is able to set an operating parameter of the auto-darkening filter and/or a prompt message, and wherein the auto-darkening filter (20) is able to be operated independently of the external apparatus.

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. And reduces the pressure on welder's head after the mask shell is flipped up.
