ESAB’s Aristo Tech 5-13 auto-darkening helmet features the latest digital lens technology, with an internal LCD display and precise control over the shade level (DIN 5 to 13), sensitivity (eight levels) and delay (0.1 to 3.5s). Adjustments to the shade and sensitivity levels are made using controls on the outside of the shell, which are easy to operate even when wearing gloves. Together the helmet and headgear weigh just 450g – considerably lighter than comparable welding helmets – and the solar powered headgear has a heat and ratch-resistant coating. A special moulding process creates a convex lens that still retains Class 1 optical levels. Options include versions prepared to accept a fresh air feed and/or hard hat, magnifying lenses and hearing protection.
