Should I be concerned with auto darkening helmet?
I have been using my auto darknening helmet for Arc and MIG welding for years and it's been fine. I have just gotten myself a TIG welder and am finding that the lens darkens quickly when the arc is struck but on the down slope the lens lightens before the arc has completely stopped. This means I get a brief period where the lens isn't darkened but the arc is still lit. It's not giving any accute vision issue but should I be concerned about any long term effects?
My understand is that whether the lens is darkened or not my eyes are protected from the damaging UV radiation.
