An automatic darkening filter with adaptive parameter adjustment includes: a welding arc intensity detection unit configured to provide a first signal for determining the welding arc intensity; a solar power supply module configured to provide electric energy for the welding arc intensity detection unit and provide a second signal for determining the ambient light intensity; and a CPU and a light valve, the CPU being configured to calculate a difference between the welding arc intensity and the ambient light intensity based on the first and second signals, and control the scale number of the light valve based on the difference. The automatic darkening filter can realize the automatic adjustment of the scale number, and in the adjustment process, the welding arc intensity signal can be revised based on the ambient light intensity, which can effectively ensure the accuracy of the final determination of the scale number.

A voltaic arc processing apparatus and method are described for processing metal workpieces, like MMA electrode welding, TIG/MIG/MAG welding, plasma welding, plasma cuts, etc., in which a welding mask includes a protective head covering worn by an operator to protect eyesight from a very intense light emission produced during processing, two or more cameras arranged outside the protective head covering to send the images of the processing to a screen arranged inside the protective head covering and visible by the operator, wherein the operator can set one or more operating parameters of the processing that are displayed on the screen.

A welding hood for protecting an operator's face comprising a face protective shield having a rearward side configured for receiving the operator's face and a viewing opening extending through the shield. The viewing opening is located in front of the eyes of the operator while the hood is fixed to the operator's head. An eye box is located adjacent the viewing opening and extends inwardly from the rearward side of the shield to block reflective arc flashes, sunlight, and/or shop-lighting from entering the operator's field of view during welding. The welding hood includes a light mounted to the face protective shield for shining light outward from a front side of the face protective shield, a cooling fan mounted adjacent the rearward side of the shield, and a clear protective member mounted within the eye box and adjacent the operator's eyes.
