What is passive lens welding?
A passive lens is usually made from a glass or plastic piece coated to a specific level to help the lens filter out light. The benefit of using these helmets is that they always stay dark, making them ideal for long passes. Passive welding helmets also do not rely on sensors or batteries. This feature eliminates the risk of burns caused when batteries or sensors underperform. The only downside about using these helmets is that you will be moving your hood repeatedly, which is tiresome, especially when doing short passes.
Why do you need a helmet for welding?
This ability saves you the hassle of having to flip the lens up and down amidst welding, which can be tiresome. The helmet is also widely preferred when doing many short welds compared to using passive welding lenses.
How to test lens sensors?
The other DIY way of testing if your lens’ sensors are operating is to use infrared rays (IR) from an ordinary television’s remote control. During welding, the helmet sensors are usually triggered by the IR from the welding arc. The helmet’s sensors can also be triggered by IR from the television’s remote control. Once the helmet’s sensors detect the remote’s IR, the sensors automatically swing into action and darken the lens. This method effectively determines the helmet’s sensors’ ability to pick signals from sideways, below, and above.
