Set the number of repetitions in the field for weld time in the COOL1 and WELD2.
(See the figure below.)
Timing chart obtained when PULSATION is set to “3”
(Note) PULSATION
When performing a welding with the setting PULSATION to 2 or more and
COOL1 (cooling time) to 0, set the control system to the primary
constant-current effective value control or the primary constant-current peak
value control. If a welding is performed with the other controls, control and
monitored value may not function correctly.
When performing a welding with the setting PULSATION to 2 or more, only
the last welding data is displayed as the monitored value of WELD2 after
completion of sequence. In the timing chart above, the data of the third time
is displayed. (See (4) MONITOR Screen.) Also, if the current gets out of the
range of upper/lower limit judgment during repeated PULSATION operation,
a caution signal is output after completion of welding. (See (5) MONITOR
SET Screen.)
