I bought a second Auto Darkening helmet at Northern Tools the other day that was on sale for $44 and change and at the same time picked up a small Halogen work light. I was welding in a new floor into my Bud's old truck, using both and I had the same problems. The cheapo had adjustable settings as well and they made a difference so I just blew it off as not being adjusted correctly. My old Auto Darkening helmet, which has no adjustments, never showed any of these tendencies that caught my attention and I paid $85 for the lens only about 10 years ago. Can't wait to see if the Halogen light effects it.
