Use of automatic darkening welding mask and replacement of accessories

Auto-darkening welding mask is a new type of eye protection, which is an auxiliary tool in the welding process. Compared with the head-mounted welding mask, it is more convenient and does not occupy the hands of the welder. The welding workpiece can be clearly seen when the welding is not performed. The lens turns black at the moment when the arc starts, effectively blocking the strong arc light, red and ultraviolet rays and other strong light. radiation.

1. The automatic darkening welding mask cannot be used for high-intensity overhead welding and overhead cutting operations, because the operation has the risk of dripping and burning of molten metal. When wearing a welding dust mask, pay attention to avoid the welding mask from affecting the airtightness of the dust mask.

2. When using the auto-darkening welding mask, please refer to the instructions for use to protect the wearer's eyes and face from harmful visible light, ultraviolet, infrared radiation, as well as sparks and splashes during arc welding and gas welding operations.

3. Please do not use it for any electric welding operation without training on the use of the auto-darkening welding mask.

4. Do not mix and match other brands of auto-darkening welding mask lenses, which will attenuate the protective performance of the product.

5. Try to use the original parts according to the product part number in the manual of the auto-darkening welding mask, such as inner protective lens and outer protective lens. Substitution with other products may impair the protection of the product and void the warranty, or cause the product to be used inconsistently with the product protection level and certification.

6. After the frame is broken or scratched, it will affect the field of view and seriously reduce the protection ability, so please replace it as soon as possible.

7. The operating temperature is -5°C (23°F) to +55°C (131°F). When the ambient temperature is low, the response speed of the liquid crystal material in the frame group will be reduced, but it will not affect its various protections performance.

8. Be sure to install an outer protective sheet on the outside of the frame case. Failure to install the protective sheet may cause damage to the frame case.

9. Replace the sweatband regularly, and replace worn parts with parts provided by the supplier.

10. Do not store the auto-darkening welding mask frame case near heat sources or moisture; do not use alcohol, gasoline or thinner to clean the frame case, and do not immerse it in water.

11. The protective sheet should be replaced when it is broken or scratched, and do not touch the filter sheet during replacement.

12. If you wear products such as myopia glasses, pay attention, when the automatic darkening welding mask is severely impacted, it may be deformed, which will cause the mask to contact the glasses and cause harm to the user.

The automatic darkening welding mask is suitable for argon arc welding and other gas shielded welding operated by two hands. It can improve the welding quality, save welding auxiliary workers, reduce the idle time of the welding machine, and greatly improve the work efficiency and workpiece quality. It is a comparison in the electric welding industry. Advanced essential protective equipment.

The automatic darkening welding mask is the same as the hand-held welding mask, which is used for welding protection, but it is different from the traditional mask. It uses the special effect of liquid crystal to be transparent before welding arc, and can clearly observe the state of the welding torch and welding parts. It instantly transforms into an opaque state, automatically completes the blocking of strong light, and plays a role in personal safety protection for welders.

principle

During the use of the auto-darkening welding mask, the sensitivity of the photosensitive probe (the probe can detect the welding arc light) can be set according to different welding operation modes and stations, until the indicator light of the sensitivity to be selected is on.

If the filter does not dim during welding, turn up the sensitivity setting until the filter dims steadily during welding. If a sensitivity is too high, the filter may remain dark after the welding operation due to ambient light.

If this happens, reduce the sensitivity of the filter until the filter can be darkened or lightened as desired.

Replacement method

Replacing the outer protective sheet: Remove the silver front cover, remove the outer protective sheet that needs to be replaced, and install the new outer protective sheet on the welding filter.

Replacing the welding filter: Remove the welding filter and install a new welding filter.

Replacing the inner protective sheet: Remove the inner protective sheet, tear off the protective film of the inner protective sheet, and install the inner protective sheet into the head cover.

Replacing the battery: The filter must be removed from the solder cap before changing the battery. Pull out the battery compartment (use a screwdriver if necessary), remove the old battery and dispose of it according to local regulations, insert the new battery into the battery compartment, and push the battery compartment back to its original position. (Note that all settings will be restored to the factory settings of the product, and you need to reset the parameters of the auto-dimming lens.)

Note: Waste batteries and product parts should be disposed of in accordance with local laws and regulations. Automatic welding visors should be disposed of as electronic waste.

Check after replacement

In order to ensure the normal operation of the automatic lightening welding screen, the photosensitive probe on the automatic lightening welding screen must be kept clean, and ensure that it is not blocked by other substances. If you need to check whether the circuit board and buttons of the panel are working, you can press the button, and the LED indicator flashes to indicate that the circuit board and buttons are working normally. The main points of the precautions for the use of automatic dimming welding masks also need to be confirmed step by step to ensure better use of it for safety protection.

Because the automatic dimming welding mask provides the welder with a clear vision before welding and accurately locates the welding point, the welding quality and production efficiency of the welder have been greatly improved.
