Hello all, still kinda new at this welding stuff. I have a harbor freight auto darkening helmet and a passive helmet that has the 2x4 inch lens. I sometimes have a hard time seeing what I'm welding with the auto darkening helmet because of the green tint. the passive helmet has a shaded flip lens that goes over the clear lens. I actually like the passive helmet because it doesn't have the green tint when I strike the arc and the image is much clearer. however I'm having a hell of a time flipping the helmet down properly. sometimes it doesn't go all the way down. I want to get the hang of this since I've flash myself a few times when I inadvertently touched the metal before I could flip the lens down in time. does the helmet need to be adjusted a certain way? thanks
