Welding mask Solar Automatic Li battery Electric DIN4/9-13 TIG MIG Welding helmet Auto Darkening

Function:Auto-Darkening Welding Helmets are designed to protect the eye and face from sparks, spatter, and harmful radiation under normal welding conditions auto-darkening filter automatically changes from a light state to a dark state when an arc is struck. And it returns to the light state when welding stops.* Auto-Darkening Welding Helmets is designed & equipped with a special turnover(up & down)headband mechanism. When welder turns over the helmet to welder's head top, the headband mechanism makes helmet's gravity center to be more lower, and be coincided with the center of welder’s head. The design of welding helmet greatly lowers the fatigue of welder’s head(& neck)and make welder feel more comfortable than before while at working.* At the moment of starting welding, it automatically changes filter screen from clear to dark in only 1/25,000 sec.* Dark to clear delay adjustment: Operator can vary the time for the filter to return to clear state. * Sensitivity can be adjustable by turning the sensitivity-setting switch to high(low) position.* At the moment of stopping welding, the filter screen automatically changes from dark to light state according to your setper-delay time. (Turning the time-setting switch to the “Short” position, then, it can vary at 0.1s～0.3s; Turning the time,setting switch to the “long” position, then, it can vary at 0.6s~0.8s.)
