K3118-2 - Lincoln Electric Shade 3 Narrow Cutting & Grinding Goggles

Technical Overview of Lincoln Electric K3118-2 Goggles

The Lincoln Electric K3118-2 Cutting & Grinding Goggles are engineered to provide specialized eye protection for industrial environments requiring moderate light filtration and high-impact resistance. These goggles feature a Shade 3 green lens, which is the industry standard for oxy-fuel cutting, brazing, and heavy grinding operations. Unlike clear safety glasses, the Shade 3 lens filters out bright glare and low-level UV/IR radiation generated during these processes, reducing eye strain and preventing temporary vision impairment known as "welder's flash" from lower-intensity sources.

Structurally, the K3118-2 is distinguished by its "Narrow" fit design. This form factor is critical for operators who require a tighter seal around the orbital area or who are working in confined spaces where bulkier goggles might snag or interfere with other equipment. The frame is constructed to provide a 100% surface seal against the face, effectively isolating the eyes from airborne hazards such as sparks, metal spatter, sand, dirt, and high-velocity particles generated during chipping and machining. This seal is superior to open-side safety glasses, offering comprehensive protection from all angles.

Compliance and durability are central to the design of these goggles. They meet or exceed ANSI Z87.1 (United States) and CSA Z94.3 (Canada) standards, certifying their ability to withstand high-mass and high-velocity impacts. The lenses are treated with an anti-scratch coating, a vital feature for grinding environments where abrasive dust is prevalent. This coating preserves optical clarity over time, ensuring that the operator's vision remains uncompromised. The goggles are strictly for cutting and grinding applications and are not suitable for arc welding processes (MIG, TIG, Stick) which require significantly darker shades (typically Shade 9-13).
