SAFETY PRECAUTIONS

This headshield is not suitable for laser welding, laser cutting or overhead 
welding applications or for oxy-acetylene.

The protective plate in this headshield is breakable and will not protect 
against impact hazards.

This headshield is designed for use in grinding, arc welding or cutting 
applications such as MIG/MAG, TIG, MMA, Plasma Arc, and Carbon Arc.

Use this headshield for face and eye protection against harmful rays, 
sparks and spatter from welding and cutting.

Never place this product on a hot surface.

In the event of failure, the headshield remains protection against UV and IR 
radiation.

Do not make any modifications to this product. Protection can be seriously 
impaired if modifications are made.

When necessary, use identical replacement parts. This will ensure that the 
safety of the product is maintained.

Do not use without the protective plate installed. Do not use if any part of 
the headshield is cracked or broken.

Do not use this headshield for welding outside the range of DIN 9-13. Harm 
to the eyes and impaired eyesight may result. Always select the correct 
setting before use.

PREPARATION & USE

ADJUSTING THE HEADBAND TO FIT

1. The headband should be adjusted both in diameter and height to fit the 

wearer’s head. To do this, press the adjustment knob on the back of the 
headband and turn the nut either left or right to expand or contract the 
headband.

2. The top headband can be adjusted by bending the strap and positioning 

the peg in the appropriate hole.

3. When the headband adjusting nuts are tight, the angle of tilt can be 

quickly and repeatably adjusted using the adjusting tab, by placing it on 
the chosen peg on the headband.
