Selecting the Weld Count
You may set a counter in the Power Supply that will enable you to monitor the number of welds
made since the counter was last reset. This feature is useful for electrode maintenance. For
example, additional weld heat will be required to maintain weld quality as the electrodes wear
through use. You can preset a weld count at which you would want to dress or replace the
electrodes rather than keep increasing weld heat (too much heat can have a damaging effect on
the weld pieces).
To set the weld count:
1.
Press the COUNT key to access the
Weld Count display screen. It is
showing the preset weld count of
3000 (shown here as SET COUNT
=03000) and the number of welds
made since the counter was last reset
(shown here as WELD COUNT =
02754).
2.
With the CURSOR keys, move the cursor to the WELD COUNT field.
3.
With the DATA keys, enter the desired weld count. During Power Supply operation,
the following events take place when the weld count equals the set count:
NOTE: The Power Supply counts only good welds; that is, welds that result in
properly completed weld cycles (Engrg: Is that how it differentiates between good
and bad welds?)
a. The message END OF WELD COUNT !! will be displayed on the display screen.
b. The COUNT END signal and weld cycle END signal will be output at the I/O
connector (please see the weld cycle timing diagram in Appendix B).
4.
To reset the weld count to zero, press the COUNT and RESET keys simultaneously.
When you do, the message WELD COUNT CLEAR COMPLETED !! will be
displayed on the display screen.
Setting Control Feedback Gain
You may adjust the response speed (gain) of the control feedback in any of the three control
feed-back modes: Constant Current, Constant Voltage, or Constant Power. The value that you
