3. Pwodwi Features
The YESWELDER LYG-Q910D welding helmet incorporates advanced features for enhanced safety and performance.

Imaj 3.1: Plis paseview of the helmet's key advantages including True Color, Anti-Blue Ray, Fast Darkening, Replaceable Battery, PP-Strong Material, and LED Light.
3.1. Auto-Darkening Filter
Equipped with 4 arc sensors, the auto-darkening filter provides a rapid switching time of 1/30,000 seconds, ensuring immediate eye protection upon arc ignition. The digital control panel allows for precise adjustment of sensitivity and delay.
3.2. Panoramic View & True Color Technology
The helmet features a 3.94" x 3.27" main viewing area complemented by side views (DIN5, non-auto-darkening) for a 180° panoramic field of vision. True Color technology provides a clear and natural view of the workpiece, enhancing visibility and reducing eye strain. The optical clarity rating is 1/1/1/1.

3.5. Dual Power Sources
The helmet is powered by a combination of solar panel technology and a replaceable CR2450 lithium battery, ensuring long service life and energy efficiency. It includes automatic sleep and shutdown functions to conserve power.
3.6. Durabilité
Constructed from PP-strong material, the helmet is designed for fall resistance, impact resistance, corrosion resistance, and flame resistance, providing robust protection in demanding work environments.
4. Enstalasyon ak Ajisteman
4.1. Headgear Adjustment
Proper adjustment of the headgear is crucial for comfort and stability. Use the various adjustment points to achieve a secure and balanced fit.
- Ajisteman gwosè: Use the knob at the back of the headgear to adjust the headband's circumference to fit your head.
- Ajisteman Distans: Adjust the distance between the helmet and your face for optimal observation and comfort.
- Ajisteman Ang: The helmet's angle knob allows adjustment to any desired viewang ang.
- Tightness Adjustment: The headband's fixing knob eases adjustment and prevents the helmet from falling off during use.
