darkening filter goes dark after an arc occurs and clears when welding is
complete.
The helmet provides a complete protection against UV/IR
(ultraviolet/infrared) radiation even with shade deactivated. Two
sensors guarantee correct operation of the helmet under all conditions
and in all positions.
The helmet can be used right away. It has only to be adjusted to welder's
head size, and the correct operating parameters have to be set.
WARNING! The welding helmet conforms to welding
safety standards.
Safe use of this product requires appropriate
welding training. It should be used by trained welders only.
Do not use the helmet without a protective glass or filter.
Do not use the helmet if any of its elements are damaged. Use at
oo
ambient temperatures of -5 C to +55 C.
WARNING!
This welding helmet must not be used for cutting
with laser or oxyacetylene torches. The helmet does
not protect against explosive or corrosive substances.
The helmet does not protect against heavy impact, for example
with grinding discs.
Never put the helmet on hot surfaces.

Auto darkening welding helmet LAHTI PRO L1540500 is intended for
face and eye protection against sparks, spatter, and harmful radiation in
welding works. Conforms to EN 379:2003+A1:2009, EN 175:1997 and
Regulation 2016/425.
