Technology details
Outer and inner cover lenses
Cover lenses are the first line of defence for the advanced auto-darkening filter (ADF). The outer lens takes the impact of spatter and sparks and protects the cassette from permanent damage, while the inner lens protects it from dust and moisture on the face side. Over time, scratches and clouding reduce their clarity, which impairs vision and increases eye fatigue. Replacing these parts regularly restores the perfect clarity and sharpness typical of True-Color technology. It is a basic step for precise work, safety and eye protection.
Ergonomic nose pad
The nose pad in the Weldcap® cap is a key ergonomic part with two main functions. First, it provides stable and comfortable support, spreading the weight and minimising pressure points during long working hours. Second, its precisely designed shape is an integral part of the design that widens the field of view: it keeps the ADF at the optimum distance from the eyes. Replacing a worn pad restores the original comfort and ensures that the unique panoramic optics of the Weldcap® are fully used. It is a simple job that directly improves comfort and efficiency every working day.
Reliable ADF power supply
The auto-darkening filter in the Weldcap® cap is powered by two CR2032 lithium batteries that supply energy to the sensors and liquid crystals. Batteries running flat during work mean not only unplanned downtime but also the risk of eye exposure when the arc is struck. A spare set of batteries in the starter kit is a simple safeguard against this. It lets you swap them immediately and get back to work, keeps the protection working without interruption and avoids costly breaks. It means reliability and peace of mind at the workplace.
