Claim 4:
5. A welding helmet, comprising:
an arc detection system configured to detect one or more welding arcs that occur during one or more welding operations;
control circuitry configured to lighten or darken a lens assembly of the welding helmet based at least in part on the one or more welding arcs detected by the arc detection system, and to record a duration of an amount of time the one or more welding arcs are present according to the arc detection system, wherein the control circuitry is configured to record only the time of the one or more welding arcs detected by the arc detection system that have an arc intensity value greater than a predetermined threshold arc intensity; and wherein the predetermined threshold arc intensity is higher than a threshold intensity level where the lens assembly transitions between a lightened state and a darkened state; and
a storage device configured to store a sum of the duration of the welding arcs over a defined period of time.
