Product Features

1. During welding, the visual clarity is high, allowing for a clear observation of the weld points to ensure the quality of the welding.

2. Novel and attractive design, ultra-lightweight and durable shell.

3. Dual-filtering to prevent harmful radiation from ultraviolet and infrared light produced by electric arcs, as well as the eye damage caused by the intense light of welding.

Packing Quantity (pcs): 20

The price of the color box packaging is +5 yuan per piece.

Characteristics:

 1. Reliable light change, light change time less than 1/10,000 seconds

  2. Advanced filter technology, uniform light transmission, clear imaging

  3. When not exposed to light, the shade number is 3, providing sufficient light for preparation work and precise polishing.
