Balance value in TIG AC. (Only AC TIG).Displaying of a positive or negative value referring to
• L12:
the positive wave in the TIG AC mode.
A negative value indicates greater penetration and fusion of the electric arc in the weld bath with less cleaning of the
piece, while a positive value indicates greater cleaning of the electric arc over the weld bath but with lower
penetration.
The following figure shows two graphs with different balance value: the first graph represents the curve of the current
with a negative value balance (more penetration) in which it can be seen that there is a low percentage of positive
wave compared with the negative.
In the second graph the current curve is shown with a positive value balance (more cleaning); in this case the
percentage of the positive wave is greater than the negative one.

Pre-gas time. It makes it possible to determine the length of gas emission before the HF start.
