Review on YesWelder Auto-Darkening Welding Helmet with Powered Features by Mike Palma

I bought two of these hoods, full color and big screen, it's great, it's very light. HOWEVER I can't get the auto dimming to work with DC TIG, it works fine with AC TIG but when I switch to DC I flicker a few times before I even start adding filler wire. I spent an hour last night getting them both to auto dim based on some suggestions here, changing batteries etc and neither of them work on DC for me. Last night I went to bed with a headache and teary eyes. I will send them back to Amazon
