Abstract
Disclosed is a method for controlling a cartridge of a welding helmet having a function to display a welding operation time, which can protect the welder'"'"'s face from intense light generated during a welding or cutting operation and also, enable automated light transmittance adjustment and operation time setting on a per operation basis, enabling a welding operation to be more efficiently performed. In the method including welding operation, cutting operation, grinding operation and X-mode operation steps, which are automatically performed in sequence according to preset conditions and a light transmittance and operation time of a liquid crystal screen of the cartridge, a control unit calculates an operation time of the liquid crystal screen indicating how long the liquid crystal screen is kept dark, and the calculated operation time is stored in a memory unit so as to be displayed on a display unit in a life mode step.
