Sounds a lot like your lens/helmet is randomly switching off and going 'bright' on you. I would not expect an argon/gas problem.Attenurb wrote:No change, still got occasional flashes so bright it overwhelmed even the darkest setting [12] on my autohelmet. I got afterimage like gas welding w/out goggles.
I'd first do a sanity check on that:
- Battery/ies of the lens OK?
- Light sensor(s) not getting covered by your work or angles?
- Light sensors not dirty?
How old is the helmet? May be that the lens electronics are simply going bad if it's older.
