non auto darkening welding helmets apply advanced light detection technology and liquid crystal technology of the new welding mask. It is composed of light changing screen, side window and helmet. The working principle is that the photoelectric sensing circuit inside the mask detects the light generated during welding (mainly infrared or ultraviolet), amplifies it, triggers the control circuit of liquid crystal, and applies the corresponding driving signal to the liquid crystal of the mask (transmissive TN liquid crystal) according to the preset light transmission rate.
Liquid crystal as a light valve will change its transmittance. non auto darkening welding helmets has the advantage that the probe senses the arc light, the LCD screen quickly becomes dark, safe and reliable, you can clearly see the welded workpiece before the arc starts, the arc starts instantly and automatically darkens. Make hands completely free, greatly enhance the efficiency of work, to ensure the quality of welding, and effectively filter out the welding process to produce infrared and ultraviolet radiation harmful to the human eye. At the same time, the strong light will be reduced to the weak light that the human eye can bear.
The emergence of non-auto darkening welding helmets provides the possibility for companies to improve welding quality and efficiency. Higher welding quality, welding efficiency, and professional satisfaction of welders will have a positive impact on a company's ability to compete in the market.
Shine Science Technology is here to tell you what to look out for when using non-auto darkening welding helmets!
1, non auto darkening welding helmets can not be used for high-intensity supine welding, supine cutting operations, because the operation there is a risk of burning molten metal dripping. When wearing welding dust masks, be careful to avoid welding masks affect the dust mask airtightness.
2, use non auto darkening welding helmets please refer to the instructions for use, in used in the arc welding, gas welding operations, to protect the wearer's eyes and face from harmful visible light, ultraviolet, infrared radiation, as well as sparks and splashes of injury.
3, do not store non auto darkening welding helmets frame case in close proximity to heat sources or moisture; do not use alcohol, gasoline or thinner to clean the frame case, do not immerse it in water.
4. Use original parts, such as internal protective lenses and external protective lenses, according to the product part number in the manual of non auto darkening welding helmets as far as possible. Using other products instead may damage the product protection function and make the warranty invalid, or lead to the use of the product effect and product protection level and certification does not match.
5、After the frame is broken or scratched, it affects the field of view and seriously reduces the protection ability, so please replace it as soon as possible.
6, if there are wearing nearsighted glasses and other products to be noted that when non auto darkening welding helmets are subjected to severe impact may produce deformation, which leads to contact between the mask and glasses, causing injury to the user.
7, in order to ensure that the non auto darkening welding helmets face screen works properly, the light-sensitive probe on the face 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 screen work, you can press the button, the LED indicator flashes to indicate that the circuit board and buttons work properly. non auto darkening welding helmets use the various points of caution, but also need to gradually confirm to ensure better use of it to do a good job of safety protection.
The above is the use of non-auto darkening welding helmets related to the operation of precautions, if you have any questions or need to buy such protection products, you can consult with the staff of Shine Science Technology Oh!
