The automatic photo-variable welding mask is one of the types of welding masks, and is mainly used to protect glasses and face of workers during the electrician welding process. The biggest advantage of the auto-changing photo-welding welding mask is that it is an auto-durable face screen. The filter technology developed filters various arcs to achieve the function of protecting glasses.

Use caution

1. The auto-changing welding mask cannot be used for high-strength overhead welding and bottom-cutting operations because there is a risk that the molten metal will drip and burn. Wear electric welding dust masks, we must pay attention to avoid the welding mask affect the tightness of the dust mask.

2. When using the auto-variable welding mask, please refer to the instructions for use. It is used to protect the eyes and face of the wearer from harmful visible light, ultraviolet rays, infrared radiation, and sparks and splashes during arc welding and gas welding operations.

3. Do not use for any welding operation before training on the use of automatic photo welding mask.

4. Do not mix and match other brands of auto-welding mask lenses at random, which will cause the product's protective performance to attenuate.

5. Use original parts, such as internal protective lenses and external protective lenses, as much as possible according to the part number of the product in the auto-changing welding mask manual. Replacement with other products may damage the product protection function and invalidate the warranty, or cause the product to use inconsistent with the product protection class and certification.

6. The impact of the crushing or scratching of the frame on the field of vision and the serious reduction in protection capabilities, 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 reaction rate 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 insert the outer protection sheet on the outside of the frame box. Failure to install the protection sheet may cause damage to the frame box.

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

10. Do not store the auto-transform mask frame box in a place near heat or moisture; do not use alcohol, benzine or thinner to clean the frame box, and do not immerse it in water.

11. The protective sheet should be replaced after crushing or scratching. Do not touch the filter lens during replacement.

12. If you wear a product such as myopia, be aware that when the auto-welding mask is severely impacted, it may deform, causing the mask to come into contact with the glasses and cause injury to the user.

The automatic photo-variable welding mask is suitable for argon-arc welding and other gas-shielded welding of two-handed operation, which can improve welding quality, save welding assistants, reduce welding machine idle time, and greatly improve work efficiency and workpiece quality. It is a comparison of the welding industry. Advanced essential protective equipment.

principle

During the use of the auto-variable light 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 work stations until the sensitivity indicator light to be selected is on.

If the filter is not darkened during the soldering, increase the sensitivity setting until the filter stabilizes the light during the welding operation. If you choose a too high sensitivity, the filter may remain dark after the end of the welding operation due to the presence of ambient light.

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

Replacement method

Replace 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.

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 sheet of the inner protective sheet, and install the inner protective sheet into the hood.

Replacing the battery: The filter must be removed from the solder cap before replacing the battery. Pull out the battery cartridge (use a screwdriver if necessary), remove the old battery and discard the old one in accordance with 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 and you will need to reset the parameters of the auto-altering lens.)

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

Check after replacement

In order to ensure the normal operation of the automatic photo-luminescence welding screen, the photosensitive probe on the screen of the auto-changing photo-welding surface must be kept clean and protected from other materials. If it is necessary to check whether the circuit board and buttons of the front panel work, press the button. When the LED indicator flashes, it indicates that the circuit board and buttons work normally. It is also necessary to gradually confirm the various points of the precautions for the use of automatic photo-variable welding masks to ensure better use of it for safety protection.
