Welding Helmet Auto-darkening GEKO

GEKO Auto-Darkening Welding Mask

The auto-darkening welding helmet is designed to protect the eyes and face during welding from sparks, splashes, and harmful UV and IR radiation. The mask is suitable for welding with all methods using an electric arc - shielded metal arc welding (SMAW) with covered electrodes, as well as semi-automatic gas-shielded welding (MIG-MAG) and tungsten inert gas welding (TIG). Additionally, TIG welding (-) with low current (20A) is also possible.

In the filter cassette, there are two photosensors that react to the welding arc's light, automatically identifying the start of welding and activating the auto-darkening function. After completing the work, the filter automatically returns to the clear state. The auto-darkening filter is powered by a built-in battery charged by solar cells.

The possibility to adjust parameters and the mask's size allows for proper adaptation of the product to the type of work and customer expectations.
