APPENDIX C
SYSTEM TIMING
Input and Output Timing Signals
The following illustrations show the timing signals for different functions of the Power Supply.
Start Signal Input
Weld sequence operation varies by the setting of
START SIG. MODE
on the Mode Select screen.
Maintained Mode
If the 2ND STAGE signal stops halfway through the welding sequence (from the beginning of initial
squeeze delay time through the end of hold time), the welding sequence will halt at that point.
Note that the
END
signal depends on the
END SIG.MODE
setting.
