Latest Patents
One of Mita's latest patents is the "Pulsed Arc Welding Method and Apparatus." This invention includes a short circuit detecting circuit that identifies the duration of a short circuit occurring between a consumable electrode and a base metal. It features a comparison circuit that evaluates the integrated or mean value of the short circuit time against a set value. A control circuit then adjusts the supply time of the pulse current and the base current based on this comparison, effectively controlling the arc length.
Another significant patent is the "Consumable-Electrode AC Gas Shield Arc Welding Method and Apparatus." This method utilizes alternating current across a consumable electrode and a base metal. It operates in three distinct periods: during the first period, the electrode is positive with a higher current level; in the second period, the current is reduced while maintaining a positive electrode; and in the third period, the electrode is negative at a lower current level. These cycles are repeated, ensuring optimal welding conditions.
