Have you ever had your face and neck sunburned or deeply tanned while wearing your welding helmet? It sounds counter-intuitive. The helmet is supposed to protect you. Why isn’t it?
My wife noticed that I was looking deeply tanned after several days of welding. I also had what looked like sunburn on the sides of my neck. In addition, I had a white band at my hair-line which could only have come from the welding helmet since that is where the front part of the head-gear sits on my head. My nose is especially sensitive to sunburn and had been tingling.
