The ability to specify Time and Energy affords maximum control of the weld

process. However, when entering your specifications in the various menus

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 five 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. (“Delay Timer” must be selected as the trigger mode

see page 22 – and a value equal to or greater than 0 must be set.)

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: A review of the

Basic Weld Cycle Time

Line on page 49 gives

additional information

on how the weld cycle

and settings operate.

NOTE: If no time is set,

an error message (“Set

Weld Timer”) will

display prompting a

parameter entry.
