Step Delay welding fitler lens Features introduction and advantage

During the welding, ADF is normally in the dark state 13, 14 or dark state 10, 11 to protect the welder's eyes from strong welding arc, when the welding work completed welding arc disappeared, the normal ADF shade will directly change from dark state to bright state in 0.1 to 1 second short time , which make the eyes needs to adapt to the extreme brightness change from dark to bright in very short seconds and make eyes discomfort. The step delay function perfectly solves this pain point, after the end of welding, ADF is not directly changed from dark state to bright state, but first change from dark state to shade 5, and then turns to light state, so that the eye has an adaptation process and feels more comfortable
