c. PULSATION / INTERVAL 1 to 3
Set the number of repetitions
PULSATION (01 to 19)
and the downtime (
INT1
to
3
) in
WE1
to
3
(See the figure below). However, when the number of repetitions is set to 01, the downtime
does not work.

•
When performing a welding with the setting
PULSATION
to
02
or more and
INT1
to
3
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 02 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 the MONITOR screen.
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 the
MONITOR SET
screen.)
d. WELD TRANS FREQ
Sets the frequency of the welding transformer to be used. It can be set 600 Hz to 1000 Hz in
units of 100 Hz. If a value greater than 1000Hz is entered, a SET ERROR will result upon
firing.
