IMPORTANT SAFET INSTRUCTIONS
The purpose of safety rules is to attract your
attention to possible dangers. The safety symbols
and the explanations with them, require your
careful attention and understanding. The safety
warnings do not by themselves eliminate any
danger. The instruction or warnings they give are
not substitutes for proper accident prevention
measures.
SAFET ALERT S MBOL. Indicates
danger, caution or warning. ay be used
in conjunction with other symbols or
pictures.
Failure to obey a safety warning can result in
serious injury to yourself or to others. Always follow
the safety precautions to reduce the risk of fire,
electric shock and personal injury.
Do not attempt to operate this product until you
have read thoroughly and completely understood
the safety rules, etc. contained in this manual.
Failure to comply can result in accidents involving
fire, electric shock or serious personal injury. Save
this Owners Operating anual and review it
frequently for continual safe operation and for
instructing others who may use this product.
WARNING
To reduce the risk of injury, the user must
read and understand the operator’s
manual.
SAFET INSTRUCTIONS
WARNING. This helmet is not suitable
for use with laser or gas-welding.
Ensure all workshop safety rules, regulations, and
conditions are complied with when using welding
equipment. The helmet will not offer protection
against mis-use of workshop tools, equipment, or
accessories.
aintain the helmet in good condition and protect
cartridge from liquid and dirt contact.
Never open or tamper with the shade cartridge.
Select the shade level before use.
Ensure the front cover lens is securely in place
before use.
Fit the helmet and adjust the head band so the
helmet will sit as low and near to your face as
possible.
Use helmet only in temperatures ranging from
-20ºC to 65ºC (-4ºF to 149ºF).
The eye protective plate in helmet is not
unbreakable. Helmet will not protect you against
severe impact hazards (such as, but not limited to)
fragmenting abrasive discs/grinding wheels, stones
and other grinding tools, explosive devices or
corrosive fluids. The helmet will only protect the
eyes and face from radiation and sparks.
Remove ill fitting clothing, remove ties, watches,
rings, and other loose jewellery.
aintain correct balance and footing. Ensure the
floor is not slippery and wear non slip shoes.
Keep children and unauthorised persons away
from the working area.
WARNING. DO NOT use the helmet if
damaged or you suspect it may be
faulty.
DO NOT use helmet unless you have been
instructed in its use by a qualified person.
DO NOT get the helmet wet or use in damp or wet
locations.
DO NOT leave work place with helmet in lowered
position, as bright light source may darken
cartridge unexpectedly.
DO NOT place the helmet on a hot surface.
DO NOT use helmet without front cover lens and
frame fitted. To do so will invalidate your warranty.
Clean helmet and store the helmet in a safe, dry,
childproof location.
The materials of the helmet may, when coming into
contact with the wearers skin, cause an allergic
reaction to susceptible individuals.
Before welding always inspect the cartridge filter to
ensure that it is not damaged. To test the filter prior
to welding, direct the front of the cartridge filter to a
bright light source which will cause the lens to
darken. Then using your hand rapidly cover and
uncover the sensor. The filter should lighten
momentarily then return to a dark state.

IMPORTANT SAFET INSTRUCTIONS
DANGER. If, at any time, the face plate
in the cartridge fails to darken when
exposed to a welding spark, DO NOT
USE.
Remove cartridge and return to your dealer for
checking. Continued use of the product knowing
that the auto darkening feature is not functioning
may damage your eyes and cause blindness.
Continued use of the helmet which is not
functioning will invalidate the warranty and could
prohibit a successful claim on any insurance
company.
Never carry out repairs on or modifications to the
welding helmet. These may only be carried out by
trained experts.

ADJUSTING THE HELMET
WARNING. Before using the helmet for
welding ensure you have read and
understood the safety instructions. The
helmet comes ready assembled but
before it can be used it must be adjusted
to fit the user properly.
ADJUSTING THE FIT OF THE HELMET
The overall circumference of the headband can be
made larger or smaller by pushing in and rotating
the knob on the back of the headband (See
adjustment ‘A’ in Fig.1). This can be done whilst
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 pip 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 pip through the nearest hole (See
adjustment ‘B’ in Fig.1).
Test the fit of the headband by lifting up and closing
down the helmet a few times whilst wearing it. If the
headband moves whilst tilting re-adjust it until it is
stable.
ADJUSTING THE HELMET TILT
If the cartridge window is not aligned with the eyes
when the helmet is in the lowered position adjust
the tilt of the helmet in relation to the headband.
Referring to Fig.2 loosen the knob ‘C’ adjacent to
the tilt plate ‘D’. Lift the tilt lever ‘E’ off tilt pip ‘D’ and
rotate it to the required position. Please note there
are 5 tilt pip postions. Retighten the clamp knob ‘C’.

ADJUSTING THE HELMET
DISTANCE OF HARNESS FROM FILTER LENS
There are 3 positions possible that the harness can
be set upon to achieve the desired distance
between the welders eyes and the filter lens, Fig.3.
Ensure that the plastic protection film is removed
from both the front and rear cover lenses before
use.

OPERATING INSTRUCTIONS
Ensure that the plastic protection film is removed
from both the front and rear cover lenses.
Press the test button. If the lens does not darken,
check the batteries.
Adjust the welding helmet according to your
individual requirements.
SWITCHING ON
Select either cut (shade 5-9) or weld (shade 9-13)
on the switch (located inside the helmet on the top
right hand side of the filter) depending on your
application.
SWITCHING OFF/GRIND MODE
After the welding is complete, or to carry out
grinding after the weld; turn the filter to the off
(grind) position.
SENSITIVIT
The sensitivity can be adjusted
between 1 and 4.
If the welding current is too
small, turn it to a higher setting.
If the welding current is too high,
turn it to a lower setting.
DELA
The delay can be adjusted by
turning the dial to either 0.1
(fast) or 0.8 seconds (slow).
If the welding current is too high
and the molton pool is too bright,
you will need to turn the dial to a
higher setting.
For spot welding turn the dial to
a lower setting.
SHADE
The filter will automatically
change from the light state
(shade 4) to the dark state (see
below) when the welding or
cutting starts. The filter will
automatically return to a light
state when the welding stops
Cut: Shade 5-9
Weld: Shade 9-13
Note: Never block any of the sensors on the front
of the filter. This will stop the filter from
automatically changing to a dark state and could
cause damage to your eyes.
