- AC BALANCE
○ This parameter establishes the positive wave vs. negative wave time ratio.
The following figure shows graphs with waves with different AC balance values: “0” BALANCE
represents the optimum ratio between “Cleanliness and Penetration” “+” BALANCE represents
the curve of the current curve with an AC Balance with a positive value (cleaner); in this case the
percentage of the positive wave is greater than the negative one. “-” BALANCE represents the
curve of the current with a negative value AC balance (more penetration) in which it can be seen
that there is a low percentage of positive wave when compared with the negative.
-
Consequences of a higher value:
•
Greater weld penetration.
• Less cleanliness.
