CHAPTER 5. OPERATING INSTRUCTIONS
HF28 DC RESISTANCE WELDING SYSTEM
5-22 990-372
11. Press the voltage
V
key to save the setting as a lower voltage limit.
12. Make several more welds and verify that under normal circumstances, the limits are not
reached and the welds are not aborted. If the limits are reached under normal welding
conditions, adjust the levels and times of the upper and lower voltage limits accordingly.
13. Return to the
RUN
screen and make several welds. Observe that under normal
conditions, the welds are not aborted, and that consistent, strong welds can be produced.
14. Try making welds with only one part present. Also try making welds with misaligned parts.
Observe that the power supply terminates the weld 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.
15. Return to the
RUN
screen and
make several welds. Verify that
the Weld Stop function detects
missing and misaligned parts.
Weld Stop Waveform
NOTE:
When using the Weld Stop 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.
