auto dark welding helmets what U use

HF and a no name that had ''Chameleon'' on the electronics. The Chameleon had some sort of rechargeable battery that went south so I got it for $2 at a swap meet. I installed a few button cells and it works fine. HF works as well with a 2X larger window. I have a drop light I use to illuminate the piece as it goes pretty F'n dark, and I started using a white soapstone marker to mark the seam as I cant make it out under the shade.
