ELECTRIC ARC WELDING SHIELD (OPTO-ELECTRONIC)
Read these instructions carefully before using your Optoelectronic welding shield. In order to ensure that this product meets your needs, it should be used and
maintained correctly, as indicated in this manual.
1.INTRODUCTION
The BARRIER optoelectronic welding shield (BARRIBL reference) comprises the BARRIHL helmet and the BARRILQ LCD auto-darkening solar lens. Both items
are manufactured according to directive 89/686/EC, and to standards EN175:1997 regarding the helmet and EN379:2009 for the LCD screen. BARRIER offers
complete protection of the head and eyes against ultraviolet and infrared rays emitted during welding operations. The lens can be switched from the clear state (shade 4)
to dark states (shades 9 to 13).
2.INSTRUCTIONS FOR USE
BARRIER may be used for all welding work but should NOT be used as protection against oxy-acetylene cutting (blowtorch) and laser welding. Do not use for
applications other than those for which it has been designed.
It is very important to read these instructions carefully and to comply with the various stages of use described below, at the risk of incurring serious eye injury.
(1) Checking the product: Before using the optoelectronic welding shield for the first time, it is important to:
- Examine the product carefully and check its marking. Ensure that the product was manufactured by Delta Plus Group, that the helmet is marked BARRIHLand that it
is fitted with its LCD lens marked BARRILQ;
- Examine the product carefully and ensure there is no damage, including on the inner and outer faces of the LCD screen, its solar sensor, its shell as well as its harness;
- Ensure that the whole product and its accessories are properly assembled and ready for use (see. figure p40);
- Check the operation of the product by putting it as close as possible to an electric arc. It should switch automatically from the clear to the dark state, otherwise it is
damaged;
- Remove the protective film from the screen before use.
If the product is not conformed, please contact us.
(2) Assembly: If you need to dismantle your BARRIER product and then reassemble it, refer to drawing P40. The product should be assembled carefully (do
not omit or leave any parts unassembled),
- Mount the headgear assembly;
- Fit the LCD lens in place. The BARRIER model is equipped with a BARRILQ reference LCD lens;
- The protective screen should be fitted in front of the welding shield in front of the LCD lens. The outer face of the LCD lens should not come into direct contact with
the welding arc. To install flatten it into the slock and put on the 2 fastener peices (from inside to outside of the mask), then screw them in.
(3) Adjusting the BARRIHLreference helmet: You can adjust the headgear assembly using its button (press and rotate) to tighten to fit your head size. Then
try on the shield before using it for work. For a finer adjustment of your field of vision you can also modify the position of the stud located under the left and right-hand
screw of the headgear assembly.
(4) Adjusting the BARRILQ reference LCD lens: The LCD lens is equipped with 3 adjustable buttons. For optimum performances of the shield it is
important to adjust them properly, according to your work conditions. The three functions are the shade adjustment to the dark state, switchover time and sensitivity:
- Sensitivity, (SENSITIVITY) button: Use it to adjust the filter to different light levels in various welding process. We recommend a Mid-range sensitivity setting for
most applications.
Set sensitivity according to lighting condition:
At position "LOW" when the surrounding light is bright and at position "HI" when the surrounding is dim.
Select sensitivity according to welding current:
At position "LOW" during high current welding and at position "HI" during low current welding.
- Scale or shade number, (SHADE NO) button: Adjust the shade according to the intensity of the current & the welding process you are using. The darkest shade is
13, the lightest is 9. Adjust the button according to the desired shade (see table 3).
- Switchover time, (DELAY) button: Adjust the delay button to an appropriate position. The switchover time is about 0.6s. Position "I" indicates that there is little
reaction time, i.e. there is no or relatively little time between the dark and clear state. This position is mostly used for spot welding. Note: the two other positions "-"
and "+" indicate respectively a fast "-" or slow "+" reaction time. The fast reaction time is about 0.2 second; the slow reaction time is about 1 second. You can adjust
the desired switchover time, within this range, according to your conditions of use.
You should be noted the conditions in which your LCD filter is to be used (see table 3).
(5) Minimal strength: The welding helmet complies with the minimum strength requirements of the standard EN175:1997
(6) Replace batteries: The ADF filter uses two CR2450 lithium batteries. We should change the battery immediately when the light indicative LOW
BATTERY is on. Open the 2 battery compartments in the direction indicated above. Replace old batteries with new ones. The anode (+) battery must remain at the
top. Insert the 2 compartments, then check that the LCD filter functions correctly.

3.STORAGE AND MAINTENANCE

 Store your equipment in a clean, cool, dry place in its original packaging;
 Keep the photoelectric cell clean;
 After use check the protective screen. You can wipe it, if necessary, with a soft clean cloth or clean with a mild detergent or alcohol.
 The protective screen might be damaged (scratches / cracks). It should then be replaced (BARRIPPIN reference). Remove the protective film before replacing it;
 Your product should be checked regularly by qualified people.

4.WARNING AND PRECAUTION

 If the LCD lens does not darken when you use it, if there is no reaction during welding, if the lens flashes and/or is unstable, if the lens darkens but returns to the clear
state, then the LCD lens may be damaged. It should not be used. Contact us and replace it immediately;
 If the LCD lens shatters or can no longer switch from the clear to the dark state when you use it, change it immediately;
 Never use a damaged screen;
 Do not modify this product, only use the accessories designed for it. Contact us for further information;
 Keep your workplace clean and tidy. Cluttered workplaces cause accidents;
 The work place should be well lit. Work in dry conditions not in damp environments away from gas or inflammable liquids;
 Dress appropriately with welding clothes, gloves and non-slip shoes. Avoid wearing jewellery and loose clothing:
 Keep out of the reach of children;
 Parts which may come into contact with wearer's skin and could cause allergic reactions to susceptible individuals;
 The LCD lens shall only be used in conjunction with a suitable backing ocular;
 Read the instructions and the markings on the products carefully.
Attention: The above warnings and precautions for use cannot cover all possible situations. The user should be aware of the risks run and should use his best
