I thought mine was doing that when using high current, but it turned out to be the red glow on the metal that kept the screen dark. Is there a "sensitivity" control on your mask?
Tbh, It seems to take a little time to lighten when first switched on - so it could be a poor connection in the helmet, but yes, I thought that it may be reacting to a hot spot on the work piece at first: until it stopped reacting straight-way when using from 'cold'.
I havn't played with the sensitivity knob since I set it years ago: but I will have a fiddle with it next time I'm near my welder.....
