Welding Glass

Product Description
The main component in welding masks and laser goggles is the welding lens, which also goes by welding glass, protective lens or welding goggle lens. Among welding hazards is eye damage from visible light that triggers flash blindness, leaving eyes red and tearful and in serious cases producing blind spots, so correct eye protection is essential.
Welding glass addresses exactly these dangers: it stops infrared and ultraviolet radiation from passing through effectively and reduces the incident visible light, yet workers looking through the lens can still observe the working condition clearly.
AUGTON GLASS stocks welding glass from DIN 4 to DIN 16 in clear, black, golden and silver. Standard sizes run from 75x98mm to 165x110mm, phi50mm rounds included, and custom sizes are made to order for mask manufacturers worldwide.
