The Udhyogi 6PAU (KT Automation reference KTI15018001FSUM) welding face shield is an industrial eye and face protection assembly engineered for seamless integration into multi-tier personal protective equipment (PPE) systems. Built around a 280 g dark green PVC wrap-around frame, the shield provides full facial coverage while maintaining mechanical and geometric compatibility with industrial headgear, optical filter plates, and corrective eyewear.
Industrial Safety Helmet Compatibility
The 6PAU welding shield is engineered with a universal type clip attachment mechanism designed to mount directly to protective industrial hard hats. The mounting assembly is specifically designed to be worn with the Udyogi 'Ultra' safety helmet, locking securely onto the helmet brim to deliver stable head-and-face integration during active operations. The universal clip architecture allows the assembly to deploy directly over the helmet shell without compromising the stability, weight distribution, or head retention of the helmet suspension system.
Welding Filter Lens and Window Interchangeability
Supplied as an unfilled frame without glass, the 6PAU features a dual-layer flip-type front window designed to house two standard viewing plates: a passive clear protective cover glass and an optical DIN filter glass. This flip-front mechanism enables operators to alternate instantly between active welding and slag inspection or grinding without detaching the shield from the helmet assembly.
- Aperture Dimensions: Accommodates standard welding filter plates measuring 4-1/4 inch x 3-1/4 inch (4.25 x 3.25 inch / 4^1.2 x 3^1.2 inch).
- Filter Configuration: Dual-slot retention mechanism designed to secure both a clear safety backing glass and an interchangeable DIN shade welding filter simultaneously.
- Radiation and Optical Attenuation: When paired with appropriate DIN filter glass, the system completely blocks infrared (IR) emissions from welding arcs and delivers 99% to 99.9% ultraviolet (UV) protection.
- Certified Optical Quality: Validated for zero distortion under EN 166 optical quality metrics, covering astigmatic refractive power, prismatic refractive power, and light diffusion.
Prescription Eyewear Integration (OTG Compatibility)
The wrap-around dark green PVC body is engineered with extended stand-off distance across the bridge and ocular regions, ensuring complete over-the-glasses (OTG) clearance. The internal cavity fits over standard prescription spectacles with zero contact against prescription frames, temples, or lenses. This provides complete high-speed impact protection, liquid splash deflection, and hot spatter exclusion for operators wearing corrective eyewear beneath the shield.
Process and Industrial Application Matrix
The 6PAU visor is certified to standard EN 166 and ANSI Z87.1 for mechanical high-speed impact resistance against small and medium flying fragments, making it compatible with severe hot-work operations across multiple heavy industries:
| Industry Sector | Compatible Thermal Processes | Target Hazards |
|---|---|---|
| Automotive Manufacturing | Spot welding, soldering | Weld spatters, molten micro-droplets, mechanical flash |
| Chemical Processing | Heavy, medium, and light gas welding | Chemical splashes, thermal radiation, radiant gas emissions |
| Pharmaceutical Engineering | ARC welding installations | High-intensity optical radiation, arc flash spatters |
| Cement & Construction | Atomic hydrogen welding, torch brazing, heavy/medium/light cutting | High-speed impact fragments, intense thermal heat, slag debris |
