KP4627-1 - Lincoln Electric Viking 1740/1840 Outside Cover Lenses (50-Pack)

Premium Protection for Your Viking Helmet

The Lincoln Electric KP4627-1 Bulk Outside Cover Lenses are an essential consumable for professional welders utilizing the VIKING™ 1740 and 1840 Series auto-darkening helmets. This bulk package contains 50 high-quality replacement lenses, designed to provide a cost-effective solution for busy fabrication shops and industrial environments where lens turnover is frequent. By purchasing in bulk, facilities can ensure that their welding operators always have access to clear, undamaged lenses, which is critical for maintaining both safety standards and work quality.

Superior Impact Resistance and Clarity

Manufactured from durable polycarbonate, these outside cover lenses are engineered to withstand the rigorous conditions of industrial welding. They serve as the primary shield for your helmet's sophisticated Auto-Darkening Filter (ADF), protecting it from molten spatter, high-velocity debris, and smoke residue. The lenses meet strict ANSI Z87.1+ and CSA Z94.3 standards, offering certified impact resistance that you can trust. Despite their rugged construction, they maintain exceptional optical clarity, ensuring that the welder's view of the puddle remains unobstructed and distortion-free.

Precision Fit and Easy Maintenance

Designed specifically for the Viking 1740 and 1840 shells, these lenses measure exactly 114 x 100 x 1.0 mm (4.5 x 3.94 x 0.04 in.). This precision sizing ensures a tight seal against the helmet gasket, preventing smoke and particulates from bypassing the lens and damaging the ADF or irritating the welder's eyes. Regular replacement of the outside cover lens is vital; a pitted or scratched lens can cause arc flare and reduce visibility, leading to eye strain and poor weld defects. With this 50-pack, maintenance becomes a seamless part of the daily routine, keeping your equipment in peak condition.

Industrial Grade Reliability

Lincoln Electric is a global leader in welding technology, and their accessories reflect the same commitment to quality as their machines. These cover lenses are an integral part of the Personal Protective Equipment (PPE) system, ensuring that the high-performance optics of the Viking series are preserved. Whether for structural welding, heavy fabrication, or general maintenance, the KP4627-1 lenses provide the reliability professionals demand.
