LYG-W700A Fan-Cooled LED Auto-Darkening Welding Helmet

The YESWELDER LYG-W700A takes welding comfort and visibility to the next level with a built-in cooling fan, dual LED work lights, and true color optical clarity — all powered by a rechargeable lithium battery with solar assist. Built for TIG, MIG, Stick, Plasma Cutting, and Grinding.

Key Features

• Built-in Cooling Fan – Removes hot, stagnant air to keep you cooler and more comfortable throughout long welding sessions
• Dual LED Work Lights – 2-level adjustable white LEDs illuminate contours and edges of the workpiece, improving precision and safety in low-light environments
• True Color Lens – 1/1/1/1 Optical Clarity – Reduces traditional lime green tint for a natural, undistorted welding view with less eye strain
• Fast Auto-Darkening – <1/30,000s response time with 4 premium arc sensors
• Wide Shade Range – Light: DIN 4 | Dark: DIN 5–9 / DIN 9–13 (outside variable)
• USB Rechargeable + Solar Assist – 1200mAh lithium battery, fully charged in ~4 hours; solar assist extends battery life
• UV/IR Protection – Up to DIN 13
• Multi-Process Compatible – TIG, MIG, Stick, Plasma Cutting, and Grinding
• Ergonomic Headgear – Oversized comfort cushion with extensive adjustability for all-day wear
• Low Voltage Indicator + ADF Self-Check – Built-in diagnostics for reliable performance

Built-in Fan

The integrated cooling fan continuously removes hot, stagnant air from inside the helmet — keeping welders cooler and more comfortable throughout the welding process, even during extended sessions.

LED Work Lights

Two front-mounted white LEDs with 2 adjustable brightness levels increase visibility of workpiece contours and edges, making precision welding easier and the work environment safer at night.

Independent Power System

• Helmet: Rechargeable 1200mAh lithium battery + solar assist — fully charges in ~4 hours (indicator turns green when fully charged)
• Fan & LED: USB rechargeable, independent from the helmet ADF power supply

True Color View

True Color technology preserves the 1/1/1/1 optical clarity rating while significantly reducing the traditional lime green tint — delivering a cleaner, more natural view of the weld pool for better accuracy and reduced eye fatigue.
