For welders who frequently replace the helmet battery, "re-adjusting parameters every time the battery is replaced" is a tedious hassle. Custom settings that match their own operating methods, such as light-shielding level, sensitivity, and delay time, often reset to zero when the power is cut off, requiring repeated knob adjustments to adapt to personal habits each time. The AUTO-MEMORY (Auto Memory) function is the helmet's thoughtful assistant that helps welders "retain settings". From the diagram, we can clearly understand its working logic: before replacing the battery, the helmet has been adjusted to parameters suitable for the work (e.g., Shade level 9, Sensitivity, and Delay time 3). Even if the helmet is temporarily powered off during battery replacement, after installing a new battery, AUTO-MEMORY will automatically restore the previously saved parameters. The settings on the panel will be exactly the same as before the battery replacement, eliminating the need for repeated manual adjustments. The practicality of this function lies in the details: Time-saving: There is no need to spend a few minutes adjusting parameters every time the battery is replaced; you can start working immediately after installing the new battery. Habit consistency: Custom parameters match the welder's own welding techniques. The memory function ensures consistent parameters for each work session, avoiding welding quality issues caused by parameter changes. Adaptation to frequent battery replacement: For welders who work for long hours and consume battery power quickly, there is no need to repeatedly troubleshoot settings, which saves trouble and maintains a stable work rhythm. In short, AUTO-MEMORY turns the hassle of "battery replacement = re-adjusting parameters" into the convenience of "immediate use after battery replacement". It is a detailed feature that makes welding operations more smooth.
