Hello. First post here.
I just got a 250ex tig and a fabricator mask. It's pretty sweet getting to learn on the 250ex, but I have a problem (I'm probably just doing something wrong). I think it's the mask (because without the mask, the arc doesn't seem to get drastically brighter or dimmer when watching the reflection on the wall)
When welding some 24ga sheet metal @ 20-30 amps, the shade level on the mask instantly jumps from pretty shaded, to hardly shaded. When the shade level jumps down, it's not a blinding light, but the light is bright enough where it's hard to see my weld area anymore. I was welding yesterday night with my friend (who has some weld experience, but none with an auto dimming mask), and he had the same problem. I tried to make sure the sensors were right perpendicular to the arc, but I don't think that made a considerable difference.
sensitivity was set to 3 bars
shade level was 8
delay was fast
