So I got flash burned like 15-20 times prolly at my welding class tonight. Speedglass auto darkeners dont like TIG welding I guess. Id be welding alone then all of a sudden i see full arc...AHHHH peices of crap, and it wasnt the batterys cuz the teacher had some and we swaped them out and it still did it. Must justbe the way the photosensors are or somethin. Anyway, cold wet cloth on my eyes when I go to bed right. Anyone else got any ideas that will help?
