CHAPTER 5. OPERATING INSTRUCTIONS
HF-2500A HIGH FREQUENCY WELD CONTROL
5-18 990-371
Try making welds with only one part present. Also try making welds with misaligned parts.
Observe that the power supply terminates the weld during the first pulse as soon as the voltage
limits are reached. If the voltage limits are not being reached with these conditions present, return
to the voltage monitor screen and adjust the limits accordingly. You may also have to adjust the
Pulse 1 current from the RUN screen if needed to optimize the Pre
-Weld Check settings.
The Pre-Weld Check function can now
be used to detect misaligned or missing
parts before the Pulse 2 welding current
is delivered to the parts.
