The welding program must be set in order to carry out the first welding spot, which is with an
adjustment enabling to obtain the necessary current with the starting electrodes diameter:
15 kA.
Now the welding process can begin. Current will change according to the programmed
increment rule. The graph below shows its pattern.

On having completed the 4000 welding spots, the control unit stops the production cycle and
displays the following message:
STEPPER [164]
END
WARNING ON TOOLS T1
PUSH [///] TO RESET
Now the operator replaces the electrodes (or restores their original diameter) and clears the
spots counter relevant to the tool the electrodes of which were replaced to clear the stepper
calculations.
The TE700 resets the initial work parameters and begins a new stepper phase.
