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.
