Put up a welding curtain around someone that is welding near you i the shop. It does help. As for the tapping the stinger before you get the helmet down, that's just mistiming. Wen you get welding alot, the lift up and flipping down messes with the side screw adjustment and it sometimes gets tighter. Tight enough that you don't nod your head hard enough and it doesn't come down all the way. Thus, getting a little extra sun tanning on your face. LOL Most of the time, it's either accidental or jut plain not paying any attention. But sometime, just sometimes, it's our own fault and we are dead to rights guilty just as JWB has said. We have all been there and we all will most likely be there again. And again, and again... It's just our natural reaction to cut corners to pick up some time so we just "Hillbilly" the job.........
