The adjustable shade control ranges from 9 to 13, selected via a convenient rotary knob on the side of the helmet, allowing precise customisation for different welding applications and material thicknesses. An inactive shade of 4 provides safe visibility when not actively welding. Solar cell power eliminates the need for battery replacement, ensuring reliable operation throughout the working day. Built for workshop versatility, the integrated grinding function enables users to switch between welding and grinding tasks without removing the helmet, improving workflow efficiency.
