Jasic JH-HD User Manual
Information manual for the Jasic JH-HD welder protective helmets complying with Par.1.4 of Appendix ll of
the EC regulations. The Jasic JH-HD welding helmets are high quality products that contribute to the comfort
and safety of the welder. The Jasic JH-HD welding helmet may be used only in connection with arc welding.
Table 1 below shows how to choose the most suitable shade level:

Information
The Jasic JH-HD welding helmet gives reliable protection for the eyes whilst electric arc welding. It offers
permanent protection against UV/IR rays, heat & sparks in any state from clear to dark. The protection
shades of the Jasic JH-HD welding helmet have been chosen to avoid eye damage caused by the welding
arc.
Do not look directly at welding rays with unprotected eyes when the arc strikes. This can cause a painful
inflammation of the cornea and irreparable damage to the lens of the eye leading to cataracts.
The Jasic JH-HD helmet allows the welder to see the point of arc strike more precisely. This leads to real
time saving. The helmet does not have to be flipped up and down during welding allowing both hands to be
kept free. The helmet is lightweight thus reducing user fatigue.
Range of application:
The Jasic JH-HD welding helmet can be used for the following applications:
Electrode
MIG
MAG
TIG (>5 A)
It is not suitable for use with laser systems and oxy-acetylene (gas welding) applications.
Potentially not suitable for overhead welding, a risk assessment should be carried out to determine suitability

for the application.
When pulse welding aluminum and stainless steel, it is essential that the welding helmet is kept a minimum
distance of 300mm from the weld and where welding runs are greater than 5 minutes it is recommended that
a heat reflective spatter lens be fitted (HR BL07). Failure to observe these criteria may invalidate the product
warranty.
The welding filter must not be used for any other purpose other than welding. It should never be used as
sunglasses whilst driving as this could lead to incorrect identification of traffic light colours.
The welding filters operate well under extreme low lighting and very strong sunlight.
Operation
Adjustment of headgear:
The Jasic JH-HD welding helmet is equipped with a comfortable headgear that can be adjusted in three
different ways.

Servicing and maintenance
The Jasic JH-HD welding helmet should not be dropped. Do not place heavy objects or tools (hammers etc.)
on or inside the helmet so as not to damage the electro-optical filter.
Always make sure that the helmet is equipped with an outside and inner lens (in front of the filter on the
outside and on the inside behind the filter). These protection lenses must be replaced if damaged in any way
(see overleaf). They are consumables and should be checked and replaced regularly.
The filter should be cleaned when changing the protection lenses. This can be done by any of the following
ways:
•Wipe with a clean, dry piece of cloth
•Clean with a piece of smooth cloth moistened with pure alcohol
•Clean with a commercial disinfectant
•If used properly the welding filter requires no further maintenance during its lifetime
If a filter should be replaced on the Jasic JH-HD welding helmet, use exclusively certified products
(DIN-CE marks). Only Wilkinson Star welding filters can be used in these helmets.
The filter itself contains no special or toxic products and can be disposed of in the same way as other
electronic devices.
Replacing the outer spatter lens:

Ensure that the helmet is always equipped with an outside lens (before the filter, on the outside of the
helmet) and an inner lens (behind the filter, inside the helmet). These protection lenses must be replaced if
broken, damaged or covered with welding spatter to such an extent that vision is impaired. Inner & outer
lenses are consumables and must be replaced regularly with certified Wilkinson Star spare parts (CE
marked).
Before using the Jasic JH-HD 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.
Inserting and removing a new protection lens:
To insert / remove the front protection lens – from the front of the helmet, simply pull the lens out from the
bottom finger aperture. Insertion is from the front – just ensure the new lens is inserted correctly into the
slots.
ADF settings:
To allow the filter to switch, the sensors on the front of the filter must not be covered. The filter then switches
to the dark state when the arc strikes and to the clear state when it stops. The filter switches to the light state
when the welding arc stops.
How to set the shade:
Select the shade by pressing the shade button. The shade number is indicated as a number in the centre of
the display.
The most suitable setting can be found on the chart in this manual or chosen using your experience. This
setting can also be made manually during the welding process.
Higher shade=darker Lower shade=clearer
Before using the filter we recommend the following adjustments are made:
Turn the sensitivity to the max setting by pressing the sensitivity button (each press increases sensitivity).
Depending upon the surrounding light the filter will switch to the dark state or will flicker (if the surrounding
light is very low, the filter may not switch to the dark state). Press the sensitivity button until the filter switches
to the clear state. Sensitivity is indicated as bars in the left corner of the display.
The filter is now set to its optimum sensitivity (according to the surrounding light conditions).
Setting the delay; The clearing delay can be adjusted manually by pressing the delay button between a
fast clear (0.1 sec) and a slow clear (1.0 sec) this is achieved by pressing the button until the display
shows desired delay.

Filter testing:
Before using the welding helmet, the auto darkening filter (ADF) and helmet needs to be checked according
to the following procedure:
Check outer protection lens is clean and can be seen through.
Ensure the sensors are covered in any way and are clean.
Once these checks have been carried out you can now test the ADF.
Select the darkest shade (shade 13) by pressing the shade button shade indicated as a number in the
centre of the display and set the sensitivity to the highest setting. Now point the sensor towards a light
source, such as, an overhead light, lamp etc. The ADF should now switch to the dark state (please note
if the ADF is stored in a dark area away from light, it may need to be left out in strong light for 20 minutes
to absorb power. After 20 minutes, if the ADF still does not react, there is an issue with the sensor. Once
the filter is in the dark state you can check the shade variation is functioning correctly, simply turn the
shade knob anti-clockwise. By doing this, the shade should get lighter. If the shade does not appear to
alter then you have an issue with the shade variation.
To test the delay function set the delay to the maximum setting. Now move the filter sensor away from the
light source. It should take 1 second to return to the light state. Now alter the delay setting to the minimum
and repeat the process, the time taken to return to the clear state should be 0.1 second. If the ADF does not
react in this way then there is an issue with the delay function.
To test the sensitivity set the sensitivity to the minimum setting and point the ADF at the light source you
used to test the other functions (if filter switches to dark state move away until the filter returns to clear state).
Slowly turn the sensitivity clockwise until the filter switches to dark state (if it does not then move closer to
the light until it reacts). If the ADF does not react then there is an issue with the light sensors.
If any of the functions fail during test or in use then please do not use the ADF and contact your local
distributor.
Warning
The auto darkening filters fitted in the Jasic JH-HD helmets are not waterproof and will not work properly if
they have been in contact with water.
Welding helmets and filters only resist a certain amount of heat. Please do not place them near naked
flames or hot work areas etc.
