Fitted with solar power panel and two replaceable AAA batteries. Features sensitivity and delay speed control for switching from dark to light. This helps to prevent arc eye when welding at high power, while still providing fast switching for tack welding. Deluxe contoured helmet design gives full neck protection and protects lens from scratching when helmet is laid down. Features comfortable headband and non-slip quick-release ratchet mechanism. Suitable for MIG, TIG and arc welding. The helmet is not suitable for use with laser welding or gas welding/cutting and will not protect against explosive devices or corrosive liquids. Pitted or scratched cover lens reduce vision clarity, severely reduce impact protection and should be replaced immediately to prevent injury. Optional accessories: magnifier lens, soft bag for helmet.
