Westward 4UZY8 Auto-Darkening Helmet

The Westward 4UZY8 is an auto-darkening welding helmet built for welders who need hands-free arc detection. It uses two arc sensors to switch the LCD lens from light state 3 to dark when an arc is struck. The helmet suits general fabrication, maintenance and repair work where automatic darkening speeds up workflow.

EN379 1/1/1/2 Optical Class Limits

The lens meets EN379 classification 1/1/1/2, meaning optical clarity and diffusion are rated 1 while angular dependence and light transmission variation are rated 1 and 2 respectively. This defines the practical viewing quality: the filter stays consistent when you tilt your head, but the rating does not guarantee the darkest shade range for very high-amperage processes. Grind mode is not included, so the lens will not stay light for grinding tasks.

Nylon Shell with Westward Suspension

The shell is moulded from black nylon 23 cm wide and ships with a protective front cover lens and a CR2330 lithium battery rated for 2 500 hours. Power is supplemented by a solar cell, reducing battery changes. The compatible suspension is Westward part 45M952, so replacement headgear is sourced from the same brand. California Proposition 65 warnings apply for cancer and reproductive harm.

Questions about this item

Which shade range does the auto-darkening filter cover?

The filter switches from a light state of 3 to a dark state of 10, covering the range needed for most arc welding processes.

What does the EN379 1/1/1/2 rating tell me about optical quality?

It rates optical class 1, diffusion of light class 1, variations in luminous transmittance class 1 and angle dependence class 2, meaning very clear viewing with slight angle sensitivity.

How long will the CR2330 lithium cell last before replacement?

The battery is rated for 2 500 hours of operation, and the helmet also uses solar power to extend running time.
