PURPOSE:To prevent defective welding by providing a comparator to control so that an electric current is not supplied to a welding head when the size of a charging current for a battery is compared with a reference value and the charging current is higher than the reference value. CONSTITUTION:The welding equipment is provided with the welding head 5 to weld parts, the battery 4 to carry the current to this welding head and a charging circuit 7 to charge this battery 4. The welding equipment is further provided with a detection circuit 8 to detect the size of the charging current of this charging circuit 7 and the comparator 10 to control so that the current is not carried to the above welding head when the size of the above charging current is compared with the reference value and the above charging current is higher than the reference value. Consequently, defective welding can be prevented and further, the welding equipment for the hybrid integrated circuit capable of prolonging the service life of the battery can be embodied. |
