Caution!
Use this welding shield ONLY for face and eye protection against
harmful rays, sparks and spatter from welding and cutting. The
protection plates are strong but not unbreakable. This shield will
not protect against severe impact hazards, such as fragmenting
grinding wheels or abrasive discs, explosive devices or corrosive
liquids. Machine guards or eye splash protection must be used
when these hazards are present, or as specified by local regula-
tions.
The Welding Shield is heat resistant and approved against stan-
dard requirements for flammability but can catch fire or melt in
contact with open flame or very hot surfaces. Keep the helmet
clean to minimise this risk.
The manufacturer is not responsible for any modifications to the
welding filter or fittings into other welding shields than Speedglas
9000 welding shields.
Protection can be seriously impaired if unapproved modifications
are made.
Persons who suffer from allergic skin reactions should make the
correct choice of headband material before using the product.
Wearers of ophthalmic spectacles should be aware that in the
case of severe impact hazards the deformation of the shield might
cause the inside of the shield to come into contact with the spec-
tacles creating a hazard for the wearer.
In all welding processes the arc should only be viewed with the
correct dark shade.
