Classic Series Filter Auto Darkening Welding Helmet Made in China

Foowoo is a Professional Auto Darkening Welding Helmet manufacturer and supplier in China. We have our own factories and production lines. Classic Series Filter Auto Darkening Welding Helmet is a core product in the field of industrial protection. It utilizes advanced optical technology to intelligently adjust the welding arc light, achieving a balance between safety protection and visual optimization.

Technical Principles and Core Functions

1. Automatic Light Adjustment Mechanism

The mask is equipped with an optical sensor that continuously monitors the ambient light intensity. It uses electrochromic (EC) or liquid crystal (LCD) technology to adjust the light density in milliseconds.

2. Fine Spectral Filtering

◦ UV/IR Blocking: Utilizing multi-layer coating technology, the transmittance of UV (313-365nm) is less than 0.0001%, and the transmittance of IR (780-2000nm) is less than 0.02%. This meets the EN 175/DIN 15 protection level.

◦ Visible Light Optimization: High-end models can use true color display technology to restore the true color of the weld pool (such as orange-red gradient, blue-purple hot zone), improving the accuracy of weld judgment, and are particularly suitable for TIG thin piece welding and new energy battery welding.

3. Intelligent Scene Adaptation

Supports multiple mode switching:

◦ Welding Mode (Shade 9-13): Suitable for high current MIG/MAG welding, with dark gray lenses providing strong shading.

◦ Grinding Mode (Shade 3-5): Reduces light density to facilitate observation of the workpiece surface treatment status.

◦ Spot Welding Mode (TW): Dynamically adjusts the shading number to reduce visual fatigue caused by frequent arc ignition.

Core Classification and Applicable Scenarios

1. Basic Filters

◦ Fixed Light Blocking Number: Such as Shade 10-13, suitable for conventional manual arc welding, with lower cost but limited flexibility.

◦ Manual Adjustable Type: Supports manual switching of dark state light blocking numbers (such as Shade 9-13), suitable for different welding currents.

2. Intelligent Adjustment Filters

◦ Adaptive Light Blocking Number: Automatically matches the dark state level based on arc light intensity (such as Shade 8-14).

◦ True Color Display Filter: Utilizes multi-layer narrowband filtering + color gamut compensation algorithm.
