Auto dark repair

[rich the mechanic]

After starting out with a hand held mask and then moving to a head mounted manual mask I got an Ebay cheapy solar auto dark (on or off) to try to see if I got on with it and was quite impressed however the other evening it started to play up and having borrowed a spare from work thought I would open up the lens cartridge to see whats inside as the lens wasn't darkening properly and had a permenant diagonal dark line to find it did have a pair of batteries inside so a little reshaping of the frame and some solering removed the dead batteries and added some wires pair of penny batteries and all clear on the lens and back to working condition checked with the tv remote just need to test tommorow if no probs a trip to Maplin for some proper battery holders and a couple of switches and I'll be able to turn it off as I don't weld as much as I would like.
