described below, keep in mind that the settings from previous use remain in
effect until you make a change and use the Enter key to register a new value.
This means that if you want to achieve a weld time of 2 seconds, for
example, you will need to ensure that other entries in the Energy menu will
allow a 2-second weld before an Energy setting is reached (and ultrasonics
are terminated).
TIME SETTINGS
There are six time parameters, or timers, that can be set. They are accessed
by pressing the Time key which allows specification of the following time
parameters. The first menu display will show the following:
Weld Time – sets the duration of time for which ultrasonic vibrations are
applied to the parts. A time value must be entered in order to weld.
Press the Time key again (and successively after each menu display) to
advance to these next screen displays:
Hold Time – sets the duration of time for which pressure is maintained to
ensure proper bonding of the parts, after the actual weld time and with
ultrasonics off. (This allows the weld to cool.)
Delay Time – sets the duration of time allotted for pressure to build up after
the parts have been contacted and before the application of ultrasonic
vibrations to the horn.
Afterburst Time – sets the duration of time for another application of
ultrasonic vibrations to the horn (for “shake-off”) to ensure that the parts
being assembled do not adhere to the horn.
Time Limit Low – sets the low time alarm examination point (as a tolerance
limit). A time alarm will be triggered if the actual weld time is less than this
value. The time low alarm will show on the Alarm Screen display and will be
indicated by a flashing LED on the Time key. By specifying values for this
limit and the Time Limit High, a weld time “window” is created that defines a
”good weld.” (If no alarms are triggered – the weld cycle occurred within the
designated time limits.)
Time Limit High – sets the high time alarm examination point. A time alarm
will be triggered if the actual weld time is greater than this value. The time
high alarm will show on the Alarm Screen display and will be indicated by a
flashing LED on the Time key.
NOTE: If no time is set, an
error message (“Set Weld
Timer”) will display
prompting a parameter
entry.
