10. 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.
Weld to a Limit Waveform
11. 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.
