Abstract
Described herein are examples of smart welding helmets with arc time tracking verification and lens maintenance detection. In some examples, the arc time tracking verification checks whether certain conditions are satisfied before tracking the arc time. This may make arc time tracking more reliable by preventing tracking during certain false positive arc detection scenarios. In some examples, the lens maintenance detection notifies an operator to clean and/or replace their lens when the lens becomes substantially occluded (e.g., due to weld spatter) and/or has been in use for a certain amount of time (and/or arc time). This may assist operators who become too engrossed in their work to notice the gradual diminishment in visibility that can be caused by slow build up of weld spatter, debris, and/or other particulates on the cover lens.
