I talk to a girl at support for speedgals. she said a tv remote will make it darken of you click the remote. It used for $480. with shipping.
I'll try useing it with the ADFLO, and try to get used to it. I think it better for my health, then have welding problems and going to a DR. that cost a lot and problay can help the welding person very much. Thanks for your help. Jim
