PRODUCT FEATURES :
¦ This model 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 1/30,000 sec.
¦ Dark to clear delay adjustment: Operator can vary the time for the filter to return to clear state.
¦ Outside sensitivity adjustable can make the operators more convenient while operating.
¦ At the moment of stopping welding, the filter screen automatically changes from dark to light state according to your per-set delay time.( Turning the time-setting switch to the "short"position~then, it can vary at 0.25s - 0.35s; Turning the time-setting switch to the "middle"position--then, it can vary at 0.35s - 0.5s; Turning the time-setting switch to the "long" position -- then, it can vary at 0.5s - 0.8s ).
¦ "WELDING"/ "GRINDING" can be selective.
¦ 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 more than 6 years.
¦ Variable shade (DIN) from DIN9 (9) to DIN13(12) is adjusted at the turn of a shade knob (shade variable).
¦ The product is in full conformity with related DIN, ISO, EN safety standards and ANSI Z87.1-2003 standards.
¦ The ultra high performance of UV/IR Auto-Darkening filters provide full protection for the user's eye & face a against UV/IR radiation during the entire welding process, even in the light state. The UV/IR protection level is up to Shade16(DIN) at all times. It makes welders feel comfortable in welding working.
