Safety Goggles SMT-221

The technical specifications and functional applications for both the SMT-221 welding goggles. Both models are engineered for industrial durability but serve distinct safety roles.

SMT-221: Double Lens Flip-Front Goggles

The SMT-221 is a specialized protective tool designed for high-heat environments where users must frequently transition between high-intensity light and standard visibility.

• Construction & Materials: The body is crafted from high-impact plastic with a green-colored frame and a secondary black frame for the lens housing.

• Dual-Lens System: It features a unique “double” lens design:

  • Outer Lens: A Dark Tinted Black Shade made of polycarbonate, used to filter intense light during welding or cutting.

  • Inner Lens: A clear polycarbonate lens that remains in place even when the front is flipped up, providing continuous impact protection.

• Ventilation & Fit: The green body is designed to provide a secure seal against the face, while integrated vents help manage airflow.

• Primary Use Cases: Ideal for gas welding, brazing, and oxy-fuel cutting.
