oxy-acetylene welding and cutting safety goggles

oxy-acetylene welding safety goggles lying on a black background. These are specialized personal protective equipment (PPE) commonly bundled together in dual sets for gas welding, torch brazing, cutting, or soldering. Here is a breakdown of the two items shown: 1. Fixed-Lens Welding Goggles (Top Left) • Design: Features a continuous, stationary protective plate built directly into a flexible, dark teal PVC body. • Functionality: Provides full-time eye defense with a permanent Shade #5 infrared (IR) filter. They are equipped with baffled ventilation ports to allow airflow while keeping stray sparks and bright perimeter flashes away from your eyes. 2. Flip-Up Front Welding Goggles (Bottom Right) • Design: Designed with a dual-lens system comprising 50mm circular viewing apertures. • Functionality: This design features a convenient hinged lift-front frame. • Flipped Down: The outer Shade #5 dark lenses shield your vision during high-intensity gas torch work. • Flipped Up: Flipping the outer lenses up reveals clear inner polycarbonate lenses underneath. This allows the user to immediately transition to chipping, weld inspections, or grinding without having to remove the entire goggle assembly.
