APPENDIX C
System Timing
Basic Weld Operation: Air Head System with Two-Level Foot Switch
Definitions
D1 Delay time from Foot Switch Level 1 closure to Weld Force start. This time ranges from 10
to 40 ms depending upon the debounce setting.
D2 Delay time from Weld Force start to Firing Switch closure. Maximum D2 time is 10
seconds. If the firing switch does not close within approximately 10 seconds, the message
FIRING SWITCH DIDN’T CLOSE IN 10 SECONDS
will display.
D3 Delay time from Firing Switch closure and Foot Switch Level 2 closure to squeeze time
(
SQZ
). Maximum D3 time is 60 ms.
SQZ Squeeze time. Selectable range is 0 to 2999 ms. Typical accuracy is -0%/+10%
Pulse 1
The timing of this weld pulse depends upon the pulse length programmed, the energy setting
and the impedance of the secondary circuit
COOL This time is not programmable by the user. It depends upon the energy level of the
second
pulse, and ranges from 20 to 670 ms on the 125ADP and 300 ADP. It can range up to 1.5
seconds on the 1000ADP. If no second pulse is programmed, this time period is skipped.
Changing pulse widths or polarities may result in longer cool times than if no changes are
made to these parameters.
Pulse 2
The timing of this weld pulse depends upon the pulse length programmed, the energy setting
and the impedance of the secondary circuit
HOLD Hold time. Selectable range is 0 to 2999 ms. Typical accuracy is -0%/+10%
NOTE: The inputs signals (FS1, FS2 and firing switch) need to be at least 50 ms duration for the unit
to recognize them.
