The figures below show graphs of the current with the automatic spot weld function
active in 2t and 4t/4bilevel mode; the first impulse, shaded, is the only one performed
if the spot weld function is set to single repetition (value of the Pause parameter equal
to 0), while all the others are performed only if the spot weld function is set to multiple
repetitions (value of the Pause parameter not 0).
