Description

Video welding mask

Technical Field

The application relates to the field of welding operation protection, and particularly relates to a welding mask.

Background

Conventionally, a known welding mask is composed of an observation window, a filter, a protective sheet, a mask, and the like. There are ordinary non-variable light face mask and automatic variable light face mask.

Common non-variable light masks have dark lenses to filter and attenuate the harmful and intense light generated by welding. The larger the lens number, the darker the color, the better the protective effect, but the poorer the visibility. The smaller the lens number, the lighter the color, and the poorer the protective effect. The color of the lens is not adjustable for the same mask, and in the welding process, particularly by current welding, the light intensity generated by different currents is different, and sometimes the use effect is poor. For safety protection, lenses with larger numbers are generally used, and the use feeling and the efficiency are low.

The automatic dimming mask detects arcing by a sensor, and the liquid crystal screen is instantly darkened to filter and weaken harmful light and strong light generated by welding. Such masks can adjust the darkness of the changing light, work relatively well with the non-changing light, but also trade off protection against visibility. In addition, the automatic light-changing mask on the market has uneven quality, high-quality basic foreign manufacturers have extremely high price, low quality cannot achieve the protection effect, and the automatic light-changing mask is relatively few in domestic use.

The basic principle of the common non-variable light mask and the automatic light mask is that harmful light is passed through a dark color lens, the light-changing delay problem of the automatic light mask is solved, the harmful light cannot be completely filtered, and the harm to welding workers cannot be completely avoided.

In conclusion, the existing masks on the market have poor protection and visibility. In addition, it is not particularly convenient to adjust to different requirements.
