How to choose a reliable auto-darkening welding helmet
Bouyean2025-09-24
With industrial development and the increasing demand for welding operations, the impact of occupational hazards on welders has drawn growing attention. As a crucial piece of eye and face protection during welding, welding helmets effectively prevent arc light from harming the health of the operator's eyes and face. Therefore, selecting a welding helmet with excellent protective performance is essential. So, how does one choose a good welding helmet? What factors should be considered?
1. Selection of the Shade Number for the Welding Filter Lens
In auto-darkening welding helmets, the ADF (Auto-Darkening Filter) is the core component. Once the sensors automatically detect the arc light, the liquid crystal darkening screen quickly turns dark, ensuring safety and reliability. Before striking the arc, the workpiece is clearly visible, and the lens darkens automatically the moment the arc is initiated. During preparation, the lens remains in a light state for easy observation by the welder. It switches to the dark state within 0.1 ms of arc ignition, eliminating the need to manually change lenses with different shade numbers, thereby significantly improving welding efficiency. Additionally, ADFs often offer multiple shade numbers to accommodate various welding operations, ensuring a clear view in the light state and a sharper view of the molten pool during welding in the dark state. The choice of ADF shade number relates to many factors, such as the welding method and process. It is advisable to choose an auto-darkening welding helmet with a wide shade number range to meet the needs of various welding methods. Furthermore, some helmets with stepless adjustment functionality allow for fine-tuning to any value within a continuous range, addressing individual differences.
2. Selection of Helmet Structure Type
Based on structure, welding protective helmets can be divided into hand-held and headgear-mounted types. The most significant advantage of hand-held welding helmets is their low cost, but their drawbacks are also evident: they prevent the use of both hands for precise welding operations and are unsuitable for welding in confined spaces. For welding tasks requiring higher quality or performed in special positions, headgear-mounted welding helmets offer distinct advantages. They free both hands, ensuring efficient and high-quality welding work.
