Sonics FM - Manual (Page 33)

The following is an example where four jobs are to be sequenced and one set
of parameters (Job 1) is to occur twice in the sequence. The sequence is as
follows:
The LCD screen will show the following displays as the jobs are sequenced:
Display for first cycle READY 1 STEP #1
second cycle READY 2 STEP #2
third cycle READY 1 STEP #3
fourth cycle READY 5 STEP #4
NOTE: Sequence repeats, going back to first cycle.
CAL PULSE
The microprocessor controlled welder calibrates itself prior to each weld
cycle. The use of the calibrator (cal) pulse enables the machine to
automatically monitor the idle losses in the converter/ booster/horn assembly
just as the head begins its descent to the part. The system adds the energy
necessary to vibrate the horn in air, to the total energy programmed to weld
a part. The cal pulse is utilized only in the Constant Energy mode, although
it is activated during all modes of operation. Occasionally, it is necessary to
turn the cal pulse off. For example, in order to place a part into the horn prior
to welding (i.e.; vacuum horns), the cal pulse can be turned on and off from
the front panel.
Press the INFO key 8 times from the READY 1 mode. The display will read
either “CAL PULSE IS ON” or CAL PULSE IS OFF.” Press the CE key, (which
will act as a toggle) and the cal pulse will be either turned on or turned off.
The system will acknowledge by showing the new (on or off) setting on the
LCD display.
