DIY Welding Helmet Auto-Darkening ADF700S fix

4/9-13  1/3/3  EN379
ANSI Z87.1




Welding is just a hobby of mine, in my free time I play around with my welding machine, I hardly use my helmet, I event kept it in the box along with the manuals, my welding helmet is about 4 years old. Last week when i was about to use it to weld some stuff, the auto-darkening is acting strange, it flickers, gets delayed until it wouldn't work anymore, I even left it under the sun to charge the battery, still no luck... :(


So heres how I fixed my auto-darkening lens.
