The Optrel Weldcap Hard is a lightweight, auto-darkening welding cap system designed specifically for workers who already wear a standard industrial hard hat. It combines the mobility and comfort of the Weldcap platform with full compatibility for safety helmets, making it ideal for construction sites, fabrication environments, and industrial maintenance work where head protection is mandatory. This system allows users to quickly mount or remove welding protection without switching helmets, making it especially useful for multi-task workflows involving welding, grinding, inspection, and general metalworking. Key Features Hard Hat Integration System The Weldcap Hard is engineered to mount directly onto standard industrial safety helmets. Benefits: Compatible with most ANSI/EN standard hard hats Quick attachment and removal system Allows welding protection without replacing existing PPE Works with hearing protection and earmuffs Auto-Darkening Welding Lens The integrated lens automatically adjusts between light and dark states depending on arc detection. Light State: Shade 3 (clear visibility for grinding and setup) Dark State: Shade 9–12 (welding protection range) Wide-angle arc detection sensor for improved responsiveness UV/IR protection at all times Expanded Field of View The ergonomic lens design provides a significantly wider viewing area than traditional welding lenses. Up to ~270% wider field of vision compared to standard 2x4 lenses Nose-cutout design brings optics closer to the eye Improved peripheral awareness Better control in tight or overhead positions Lightweight Design Despite its industrial functionality, the Weldcap Hard remains extremely light. Approx. weight: ~400 g Reduces neck strain during extended use Comfortable for all-day wear in production environments Grinding Mode A dedicated grind mode allows the lens to remain in a bright shade 3 state. Benefits: No need to remove helmet for grinding Faster workflow transitions Safer visibility during prep work Flame-Resistant Textile Construction The textile components are made from flame-retardant materials designed for industrial welding environments. Meets EN ISO 11611 (Class 1, A1 + A2) Removable and replaceable textile sections Washable for extended service life Technical Specifications Specification Value Product Number 1008.002 Light State Shade 3 Welding Shade Range 9–12 Optical Class 1 / 1 / 2 / 2 Sensors Wide-angle detection sensor Switching Time ~0.16 ms (light to dark) Fast Response (55°C) ~0.110 ms Dark-to-Light Delay ~0.3 sec Power Supply 2 × CR2032 batteries Viewing Angle Down +37° Viewing Angle Side +25° Impact Rating EN 175 F (45 m/s) Operating Temp -10°C to +60°C Storage Temp -20°C to +80°C Weight ~400 g Material Flame-retardant textile + rigid plastic shell Warranty 2 years Applications Structural steel fabrication Construction site welding MIG/MAG welding (GMAW) TIG welding (GTAW) Stick welding (SMAW) Flux-core welding Plasma cutting Maintenance welding Industrial repair work Grinding and preparation tasks Benefits Works directly with existing hard hats (no need for separate helmet) Extremely lightweight compared to traditional welding helmets Fast conversion between welding and non-welding tasks Wide field of view improves precision and safety Ideal for multi-task industrial environments Comfortable for long shifts in the field Limitations Smaller optical system compared to full premium welding helmets Not designed for laser welding applications Less enclosed protection than full-face welding helmets Dependent on compatibility with existing hard hat system
