①Try to use original parts according to the product part number in the manual for an auto darkening welding helmet, such as an automatic dimmer screen and external protective sheet. Replacing with other products 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.

②Auto darkening welding helmet cannot be used for high-strength overhead welding and overhead cutting operations, because there is a risk of molten metal dripping and burning.

③Do not mix and use lenses of different brands at will, which will weaken the protection performance of the product.

④To ensure the normal operation of the auto darkening welding helmet, the photosensitive probe on the dimmer screen must be kept clean and protected from other substances.

⑤Do not immerse the dimmer screen in liquid for cleaning, and do not pour detergent on it.

⑥If it is necessary to check whether the circuit board and buttons of the dimmer screen work, you can press the button. If the LED indicator flashes, it indicates that the circuit board and buttons work normally.
