It is then possible to start the welding process. The welding current increases according to the set stepper
function. The following diagram shows the current variations:

On having completed the 4000 welding spots, the control unit stops the production cycle and displays the
following message:
MAX SPOTS NUMBER
At this point the operator replaces the electrodes (or resets their original diameter) and clears the spots counter,
by means of the proper key, to clear stepper calculations.
The TE470/TE480 resets the initial work parameters and begins a new increment phase.
