Some dust created by power sanding, sawing, grinding, drilling, and other construction
activities contains chemicals known to cause cancer, birth defects or other reproductive
harm. Some examples of these chemicals are:
• Lead from lead-based paints,
• Crystalline silica from bricks and cement and other masonry products, and
• Arsenic and chromium from chemically-treated lumber.
Your risk from these exposures varies, depending on how often you do this type of
work. To reduce your exposure to these chemicals: work in a well ventilated area, and
work with approved safety equipment, such as those dust masks that are specially
designed to filter out microscopic particles.
Auto-darkening welding helmets
are designed to protect the eye
and face from sparks, spatter, and
harmful radiation under normal
welding conditions. Auto-darkening
filter automatically changes from a
light state to a dark state when an
arc is struck, and it returns to the
light state when welding stops.
Auto-darkening welding helmets
are ready for use. Before starting
to weld, adjust the position of the
headband and select the correct
shade number for your application.
Severe personal injury could occur if
the user fails to follow the mentioned
warnings, and/or fails to
follow the operating instructions.

Before using the helmet for welding ensure you have read and understand the safety instructions.
Instructions For Use
• The helmet comes fully assembled. Before starting to weld, adjust the helmet to fit the user properly.
• Adjusting The Fit Of The Helmet
The overall circumference of the headband can be made larger or smaller by rotating the knob on the back of
the headband. ( See adjustment "Y" in fig. 1) This can be done while wearing the helmet and allows just the right
tension to be set to keep the helmet firmly on the head without it being too tight.
• If the headband is riding too high or too low on your head, adjust the strap which passes over the top of your
head. To do this, release the end of the band by pushing the locking pin out of the hole in the band. Slide the two
portions of the band to a greater or lesser width as required and push the locking pin through the nearest hole.
(See adjustment "W" in fig. 1)
• Test the fit of the headband by lifting up and closing down the helmet a few times while wearing it. If the
headband moves while tilting, readjust it until it is stable.
• Adjusting Distance Between Helmet And Face
Step 1: Undo the block nut (See"T" in fig. 1) to adjust the distance
between the helmet and your face in the down position.
Step 2: Retighten the block nut when adjustment is complete.
• Adjusting The Viewing Angle Position
Please see fig. 2a and 2b.
