Two auto-darkening welding filters are available from Hornell. The Speedglas 9002V and 9002X feature a new electronics unit that enables the user to adjust the filters , sensitivity and delay (switching back to the light shade after welding stops). The welding filter's 'optical density' the degree of light that penetrates the filter can be adjusted too.
