6.2 System Modes
You can control the way in which ultrasonics are applied to your sample by setting the unit
to operate in one of three different standard modes, (and one optional mode). You
determine the mode and specify operating parameters for your welding process. The three
standard system modes, and one optional mode, are described below:
Table 6.1 System Modes and Description
Mode Description
Energy
In this mode, ultrasonics are determined by the calculated
amount of Joules (1 Joule = 1 watt x 1 second) expended
during a cycle. Ultrasonics will remain on until the required
amount of energy is reached or until the timeout period has
been reached unless a STOP condition occurs.
Time
In this mode, ultrasonics are applied to the sample for a
specified period of time. Ultrasonics will remain on until the
timeout period has been reached unless a STOP condition
occurs.
Continuous
Ultrasonics are applied to the sample until you stop the cycle.
In this mode the user controls the timing of ultrasonics
manually. The power supply starts when a START condition is
received and stops when a STOP condition is received.
Ground Detect Cutoff
Optional mode that allows you to switch to a scrub time
(cutting fabric) or turn off ultrasonics when the horn touches
an anvil which has been isolated from earth ground. Limits to
stop ultrasonics in this mode can be set in Continuous, Time,
and Energy modes respectively.
