Face Shield Use for Welding:
Purpose: Protects against:
Arc flash: Intense UV and infrared light from welding arcs, which can cause "welder’s flash" (painful eye burns).
Sparks and spatter: Molten metal particles that can burn skin or cause fires.
Debris: Flying particles from grinding or cutting.
 
Features:
Visor: Made of tinted, impact-resistant polycarbonate (e.g., shade 3–14, depending on welding type like MIG, TIG, or stick).
Headgear: Adjustable for comfort and secure fit.
Auto-darkening: Many modern shields have lenses that darken instantly when an arc is struck, improving visibility and convenience.
 
Standards: Must meet safety standards like ANSI Z87.1 (U.S.) or EN 175 (Europe) for impact and optical clarity.
 
Applications: Used in arc welding (MIG, TIG, stick), plasma cutting, and sometimes oxy-fuel welding. Not typically needed for low-intensity tasks like soldering.
