- Abstract: Automatic dimming electric welding mask
- The automatic dimming electric welding mask is one of the types of electric welding masks, which is mainly used to protect the operator's glasses and face during the welding process. Compared with ordinary welding masks, the biggest advantage of automatic dimming electric welding is that the welding mask is an automatic dimming mask. Through the developed filtering technology, various arc lights are filtered to protect glasses.
Precautions
1. The automatic variable photoelectric welding mask cannot be used for high-strength overhead welding and overhead cutting operations, because there is a risk of molten metal dropping and burning during the operation. When wearing the welding dust mask, pay attention to avoid the influence of the welding mask Anti-dust masks Tightness of.
2. Please refer to the instructions when using the automatic variable photoelectric welding mask to protect the wearer's eyes and face from harmful visible light, ultraviolet, infrared radiation, sparks and splashes when using it for arc welding and gas welding operations.
3. Please do not use it for any welding operation without training on the use of automatic photoelectric welding mask.
4. Do not use other brands of automatic photoelectric welding mask lenses randomly, which will weaken the protection performance of the product.
5. Try to use original parts according to the product part number in the manual of automatic variable photoelectric welding mask, such as internal protection lens and external protection lens. Using other products instead may damage the product protection function and invalidate the warranty, or cause the product use effect to be inconsistent with the product protection level and certification.
6. If the frame is broken or scratched, it will affect the field of vision and seriously reduce the protection ability, so please replace it as soon as possible.
7. The operating temperature is - 5 ℃ (23 ° F) to+55 ℃ (131 ° F). When the ambient temperature is low, the reaction speed of the liquid crystal material in the frame group will be reduced, but its various protective properties will not be affected.
8. The outer protective film must be installed on the surface of the frame box. Failure to install the protective film may cause damage to the frame box.
9. Regularly replace the sweat band, and replace the worn parts with the parts provided by the supplier.
10. Do not store the mirror frame box of automatic variable photoelectric welding mask near heat source or damp place; Do not use alcohol, gasoline or thinner to clean the frame box, and do not immerse it in water.
11. The protective piece shall be replaced after being broken or scratched, and the filter piece shall not be contacted during replacement.
12. If products such as myopia glasses are worn, it should be noted that when the automatic variable photoelectric welding mask is seriously impacted, it may be deformed, which will cause contact between the mask and glasses, causing injury to users.
The automatic variable photoelectric welding mask is suitable for argon arc welding and other gas shielded welding operated by both hands. It can improve the welding quality, save auxiliary welding workers, reduce the idle time of the welder, greatly improve the working efficiency and workpiece quality, and is an advanced necessary protective equipment in the electric welding industry.
Principle
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 during the use of the 3M automatic variable photoelectric welding mask until the indicator of the sensitivity to be selected lights up.
If the filter does not dim during welding, increase the sensitivity setting until the filter can steadily dim during welding. If an excessively high sensitivity is selected, the filter may remain dark due to the presence of surrounding light after the welding operation.
If this happens, reduce the sensitivity of the filter until the filter can be dimmed or lightened as required.
Replacement method
Replace the outer protective sheet: remove the silver front cover, remove the outer protective sheet to be replaced, and install the new outer protective sheet on the welding filter.
Replace the welding filter: remove the welding filter and install a new welding filter.
Replace 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.
Battery replacement: The filter must be removed from the welding cap before battery replacement. Pull out the battery case (use a screwdriver if necessary), take out the old battery, discard the old battery according to local regulations, insert the new battery into the battery case, and push the battery case back to its original position. (Note that all settings will be restored to the factory settings of the product. You need to reset the parameters of the automatic dimming lens.)
Note: Waste batteries and product parts should be disposed according to local laws and regulations. The automatic welding surface screen should be treated as electronic waste.
Check after replacement
In order to ensure the normal operation of the automatic variable photoelectric welding surface screen, the photosensitive probe on the automatic variable photoelectric welding surface screen must be kept clean and 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 key points of the precautions for the use of the automatic variable photoelectric welding mask also need to be confirmed step by step to ensure better safety protection.
