This product take our best and latest technonlogy of Tack Mode, Step Delay combine with our independent 6th Genations ships to bring best using experience and welding protection for users . 

Step Delay 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 eyesfrom 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

Tack Mode Features introduction and advantage
Generally, during spot welding, the welding arc will frequently switch between dark state and light state in a short period of time, so that the ADF filter also frequently switches between dark state and light state, making people eyes discomfort. Tack Mode function perfectly solves this pain point by making Shade5 to be the convert shade, when the spot welding arc disappears, ADF is not directly switched to the light state, but to shade 5, which greatly reduces the discomfort of the eyes caused by the big change of brightness and darkness, and also ensures the clarity of the view during welding work
