LYG-0V-900B Flip-up Auto-darkening Welding Helmet

The YESWELDER LYG-0V-900B is a professional flip-up auto-darkening welding helmet featuring a separate clear grinding shield — flip the lens up for grinding and non-welding tasks, flip it down for welding and cutting. Designed for welders who switch between processes frequently without changing helmets.

Key Features

• Flip-Up Auto-Darkening Lens – Quick-release front cover lens reduces lens changes and extends helmet lifespan; self-locks at the upright position for hands-free non-welding work
• Clear Grind Shield – Large 10.62" × 5.42" clear grinding shield provides full face protection during grinding and other tasks, reducing eye strain and injury risk
• Panoramic Side View – Shade 5.0 fixed side windows for enhanced situational awareness on the job site
• True Color Lens – 1/1/1/1 Optical Clarity – Natural, undistorted view for precision welding
• Fast Auto-Darkening – <1/30,000s response time, arc-sensing (not brightness-sensing) for reliable activation; auto shut-off after 3 minutes
• Wide Shade Range – Dark: DIN 5–9 / DIN 9–13 (outside variable)
• 4 Arc Sensors – Consistent darkening across all welding processes
• Rechargeable Lithium + Solar – 300mAh battery, 2-hour charge for up to 10 days of use
• UV/IR Protection – Up to DIN 16
• Lightweight, Well-Balanced Design – Reduces neck torque and operator fatigue for improved short-term comfort and long-term health
• Ergonomic Headgear – Large pivoting backing and multiple head straps avoid pressure points and over-tightening, even in downward applications
• Low Voltage Indicator + ADF Self-Check – Built-in diagnostics for reliable performance

Flip-Up Design

The quick-release flip-up lens lets you switch instantly between welding and grinding without removing your helmet. The lens self-locks at the upright position, keeping it securely out of the way during non-welding tasks — increasing efficiency and reducing downtime on the job.

Clear Grind Shield

The separate clear grinding shield provides a wide, unobstructed viewing area for grinding, cutting prep, and other tasks. Reduces eye strain and protects against debris without switching to a separate face shield.

Panoramic View

Fixed Shade 5.0 side windows give you a sense of your surroundings while welding — improving spatial awareness and safety in busy work environments.

Auto-Darkening Lens

The ADF activates by sensing the arc directly — not just brightness — for more reliable darkening in challenging lighting conditions. Auto shut-down after 3 minutes of inactivity extends battery life.
