Abstract
PURPOSE: To prevent the degradation in welding quality and reduce equipment cost by monitoring the secondary voltage and electric current of a power transformer, and controlling the electricity conduction timing for each welding machine in such a way that the load current does not exceed set values.
CONSTITUTION: A potential transformer 31 and a current transformer 32 are provided on the secondary side of a power transformer 20, and the secondary voltage and current of the transformer 20 are inputted respectively to a voltage detecting part 33 and a current detecting part 34. These data are inputted to a permissible current detecting part 35, by which the secondary current lowering below the permissible drop voltage is calculated. This current value is inputted to a welding machine selection command part 37. The welding conditions for materials 11aW11z to be welded are beforehand set in a welding condition setting part 40 for every welding machine. The start signals for the respective welding machines are inputted to a start command input part 36, and in a command part 37, the permissible current value and the sum of the set current values of the welding machines inputted with the start signal and the set current values of the welding machines under working are compared. When the permissible value is large, electricity is conducted to the welding machines simultaneously, and if it is smaller, the welding is started after the end of the electricity conduction to the other welding machines.
