The welding program should be adjusted for carrying out the first welding spot followed by the
adjustment that allows the achieving of the required current with the starting diameter of the electrodes:
15 kA.
Now the welding process can begin. Current will change according to the programmed increment rule.
The graph below shows its pattern.
