Abstract
The welding filter device includes a light sensor, a microprocessor, a liquid crystal display, and a user interface. The light sensor senses light to generate a welding signal and a light source intensity signal. The microprocessor comprises a determining module, a control module, a regulating module, and a storage module. The determining module receives the welding signal and determines whether to activate a welding mechanism. The control module receives the light source intensity signal and outputs a control signal. The liquid crystal display presents a first display status according to the control signal. The user interface is used to generate a setting signal; wherein when the liquid crystal display presents the first display status, the regulating module receives the setting signal to regulate the settings so that the liquid crystal display presents a second display status. Furthermore, a method for controlling the welding filter device is also disclosed herein.
