Looking at the video in the "welding thin metal" bit of the tutorial, am I right in thinking the video is shot through an automatic helmet? If so they must be the best thing since sliced bread! Has anyone experience of the automatic helmets from welduk.com?
I got one off ebay, and it broke in the first few days stopped auto darkening so as I'm only training I sacked it off and got a Miller fixed shade which I can uprate if I get a full time job welding
