The LOKERMANN ALIA VISTA is an auto-darkening welding helmet designed for enhanced face and eye protection during welding, cutting, spraying, and arc gouging. It incorporates advanced integrated technology, including LCD, optoelectronics detection, solar power, and microelectronics, to provide a safe, fast, and reliable auto-darkening experience. The helmet allows operators to keep both hands free, improving efficiency and weld quality by enabling accurate arc striking while protecting against sparks, spatter, and harmful radiation.

Function Description

The helmet's core function is to automatically darken the filter when an arc is struck, protecting the operator's eyes from intense light and UV/IR radiation. It then returns to a light state after welding, allowing for clear vision. The "Real Vision Technology" (ALTAVISTA HD) aims to provide improved clarity across the full spectrum of colors, enabling users to weld and grind with precision without needing to remove the helmet. This technology is designed to enhance weld quality, efficiency, and safety.

The helmet features an "ADF Saving Mode" with auto-on and auto-off functions to conserve power and extend the life of the Auto-Darkening Filter (ADF). The ADF automatically switches off when ambient light is below 3 LUX and switches on (entering stand-by mode) when ambient light is above 10 LUX.

An "Extra Heat Stability" function blocks the ADF in a dark state if the working temperature reaches 120°C. The device is designed to operate stably and maintain performance up to 100°C, ensuring welder safety even in severe conditions.
