APPENDIX C: SYSTEM TIMING
125ADP/300ADP/1000ADP DUAL PULSE RESISTANCE WELDING POWER SUPPLY
C-2 990-922
Basic Weld Operation: Manual Head System with Firing Switch Operation
Definitions
D3 Delay time from firing switch closure to the start of the weld sequence (that is, start of
SQZ
).
. This time ranges from 10 to 40 ms depending upon the debounce setting.
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 firing switch signal needs to be at least 50 ms duration for the unit to recognize it.
