welding. It offers permanent protection against UV/IR rays, heat & sparks
in any state from the clear to dark.
The welding helmet can be used for the following applications:
• Electrode
• MIG
• Mag
• Tig
The welding filters operate well under extreme low lighting and very
strong sunlight.

Claims of any kind for damages caused by improper use are excluded.
2.2 Reasonably foreseeable misuse
The device is intended exclusively as protection for the eyes against UV/IR
rays, heat & sparks in any state from the clear to dark whilst arc welding.
They are not suitable for use with laser systems and oxy-acetylene (gas
welding) applications. The welding filter must not be used for any other
purpose other than welding. They should never be used as sunglasses
when driving as this could lead to incorrect identification of the colour of
traffic light.

must be instructed with regard to the safety requirements, safety regula-
tions and operational instructions which must be applied in their work.

4. Function and use
Welding helmets afford reliable protection for the eyes whilst electric
arc welding. They offer permanent protection against UV/IR rays, heat &
sparks in any state from the clear to dark. The protection shades of the
welding helmets have been chosen to avoid eye damage caused by the
welding arc.
Welding helmets allow the welder to see the point of arc strike more pre-
cisely. This leads to a real time saving. The helmet does not have to be flip-
ped up and down during welding, both hands are kept free and because of
the helmets lightweight fatigue is reduced.
The helmet is available in 2 options. The helmet can be supplied with or
without UVIR shade 5 side windows – the side windows giving the user a
degree of side vision whilst still giving protection from the welding rays.
4.1 Operation
Before using the helmet for the first time the protective films must be
removed from the front spatter lens. The films cannot be removed from
the front spatter lens with the lens in place. Please follow the instructions
below to remove the spatter lens, see chapter „5.1 Replacing the outer
spatter lens“ on page 13
