Welding Helmet Solar Powered Auto Darkening Protective Shield with Variable Shade from DIN9 to DIN13

Auto-Darkening Welding Helemts 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.

Features:
Suitable for ARC, TIG, MIG, Spot, Micro, Wire, AC, DC, and Plasma Welders and Plasma Cutters. 
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 weldine 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 car: 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 set per-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. 
The helmet utilizes high performance solar cells as power supply and has 2 built-in 3V lithium batteries as power back-up. No change of battery is required. And the battery life is raised to a new limit. Under normal welding conditions, users can expect a battery has a lifetime of 2 years. 
Variable shade(DIN)from DIN9 to DIN 13 is adjusted at the turn of a shade knob(shade variable). 
The product is in fully conformity with related DIN, EN safety standards and ANSI Z87.1-1989 standards. 
The ultra high performance of UV/IR Auto-Darkening filters provide full protection for the user's eye & face against UV/IR radiation during the entire welding process, even in the light state. The UV/IR protection level is up to Shade 16(DIN)at all times. It makes welders feel comfortable in welding wording.
