three polarization filters are included in an auto darkening helmet. a polarization filter is a filter that reduces the amount of light that enters. now, test the lens a few times to make sure it darkens appropriately to the arc light produced during the weld. of course, you need to know your process’s voltage and amperage levels. To achieve the best results, twist the knobs on the helmet to increase sensitivity as much as you desire. the charging source can be either a light bulb or a high power lamp. step 2: now you need to check for your charging source. the basic concept behind covering the light detector is to avoid any source of light to hinder the process of charging. Step 1: seal the helmet light detector using any masking tape. once your arc is activated, uv light generated by the arc charges the solar panel for the welding hood, which then powers all the electronics.

the battery is designed to power the hood or mask initially for when you start the welding arc.

What’s are the changes in the Version 1.2.3 firmware? If the camera’s firmware is already Version 1.2.3, it is not necessary to update the firmware. The Version 1.2.3 firmware being released this time is for cameras with firmware up to Version 1.2.2.
