This might be a dumb question but do welding helmets expire? I’ve got a helmet that I used 21 years ago that hasn’t been used since. Don’t know if I’ll use it again.
Is it an auto dimming or old school single shade? Auto dimming the electronics might be fickle after all those years. The old school single shade will outlive all of us.
I have a Lincoln auto at home and work bought me a nice Miller auto dimming. Electronics are more picky on the Miller, but I didn't buy it so yea.
Many glass single shade ones have replaceable lenses. My Miller single shade is 35 years old, minimum, and I don’t weld enough to have a sore neck from using it…
The only concern that I'm aware of is with the coated plastic lenses (ex. Gold lenses). If the coating is damaged,then the lense is junk - burns and damage to your eyes can result.
If memory serves, I've used #10 and #11 glass....and 11 was dark.
Our instructor expressed faith in glass' track record.
"How long does 'fast glass' take to darken?", was the question in the early '09's.
