To adjust the lens darkness, turn the Shade Control Knob (on the left side of the helmet) to select the desired shade level from 9–13. Refer to the Shade Guide Chart in the manual to determine the recommended shade setting for your welding application.
Important: Before welding, test the auto-darkening lens. While wearing the helmet, briefly strike an arc while looking slightly away from it. The lens should darken evenly. Do not use the helmet if the lens does not darken properly.
