CHAPTER 5. OPERATING INSTRUCTIONS
HF-2500A HIGH FREQUENCY WELD CONTROL
5-20 990-371
Return to the RUN screen and
increase the weld time by 1-2 ms.
Make several welds and verify
that the upper voltage limit is
reached for every weld, and the
weld pulse stops before the end
of the programmed weld time.
Make several more welds and inspect them for consistency of weld quality and/or weld strength.
NOTE:
When using the Weld to a Limit function, always select a monitor mode that is
different
from the feedback mode. For example:
• If you are welding in constant current, put limits on voltage.
• If you are welding in constant voltage, put limits on current.
• If you are welding in constant power, put limits on current or voltage.
