TIMING DIAGRAMS
The following timing diagrams are included to help visualize all the dierent steps involved when making welds.
Timing diagrams for the three dierent weld head control options are included.
Fully Manual
D1: A delay that occurs from the time primary trigger is triggered and the signal to the weld head is sent. Typical
time for this is between 1 and 50 milliseconds.
D2: The time between when the weld head is engaged and when trigger 2 is triggered.
D3: A delay that occurs from the time the secondary trigger is triggered, and the weld occurs. Typical time for
this is between 1 and 50 milliseconds.
Pulse 1: The duration of this delay is dependent on the energy programmed for Pulse 1, set in the Pulse Set-
tings tab on the Home Screen.
Cool: The duration of this delay is dependent on the time programmed for Delay Between Pulses. The operator
can select between 1 and 100 milliseconds, which will be ignored if either pulse is disabled. Control the cooling
duration using the Pulse Settings tab on the Home Screen.
Pulse 2: The duration of this delay is dependent on the energy programmed for Pulse 2. This is controlled on
the Pulse Settings tab on the Home Screen.
D4: After this delay, alarms and warnings are sent. Typical time for this is between 1 and 50 milliseconds.
D5: After this delay the Weld Ready signal will return to a high position. This delay will depend on the time
needed to charge to the desired energy but will typically be between 50 and 5000 milliseconds.
