Built upon the proven 5400 Series elastomeric full-face platform, this specialized configuration includes a factory-mounted or shade-adaptable flip-up welding shield over the high-impact polycarbonate lens. Crafted from a soft, non-allergenic elastomeric material with a 4-strap headband suspension harness, it ensures a tight, comfortable face seal while shielding the operator against hazardous welding fumes, metal spatter, infrared\/ultraviolet radiation, and airborne particulates via dual N-Series threaded cartridge connectors.\u003c\/p\u003e\n\u003chr\u003e\n\u003ch3\u003eTechnical Specifications \u0026amp;
