Abstract
Disclosed is a welding helmet including an anti-blinding device to selectively control a welding operation and a grinding operation, and more particularly, a welding helmet, which stably protects the welder's eyes and enables easy switching of the anti-blinding device from a welding operation mode to a grinding operation mode or vice versa without taking off the welding helmet. In addition to the anti-blinding device to protect the welder's eyes from light emitted from a welding or cutting torch during a welding or grinding operation, a switch is provided at an outer surface of the welding helmet to allow a welder to conveniently select a welding operation mode or a grinding operation mode without taking off the welding helmet.
