This Optrel Panoramaxx & Helix shade + 1 lens attaches directly to the inward facing side of the auto darkening filter, replacing the standard ADF inner lens - extending the shade level by 1. Suitable for all Optrel Panoramaxx and Helix welding helmets.
Replacing the standard ADF inner lens for all Helix and Panoramaxx welding helmets, the shade + 1 lens increases shade levels by a factor of one. For example, a welding helmet with an ADF featuring an inactive shade level of 3 would be increased to 4 and shade levels of 8-13 would be increased 9-14.
