Capacitive welder and method for charging same

A method of charging a capacitive welder, the capacitive welder including:

• a charging circuit having a switching element;
• a welding transformer having a primary winding and a secondary winding;
• a capacitor to which an input electric power is introduced via the charging circuit;
• a discharge switching element connected in parallel with the primary winding and the capacitor, the primary winding being connected in series to the capacitor;
• a bypass switching element connected in parallel with the primary winding;
• and
• welding electrodes connected in parallel with the secondary winding of the welding transformer,
• the method comprising:
• bringing the welding transformer into a reset allowing state by causing a reset current to flow into the primary winding using the input electric power introduced through the charging circuit without supplying an ON signal to the bypass switching element;
• and then supplying the ON signal to the bypass switching element such that the capacitor is charged through the bypass switching element by the input electric power introduced through the charging circuit.
