3.7.1.1 AC balance (%)
The balance is set as described in Chapter 3.4.2.
The balance setting can only be made in connection with AC current welding in
the case of TIG. It ranges from -80% to +80% and makes it possible to influence
the arc shape, penetration and cleaning when welding aluminium within an
extremely broad range. The negative and positive welding current is extremely
evenly distributed in the centre position (50%). With increasing negative values
the proportion of the negative welding current increases (up to -80%) and the
positive proportion decreases. This makes the arc narrower and generates
deeper penetration with less electrode loading. With increasing positive values
the proportion of positive welding current is increased (up to +80%) and the
negative proportion decreases. The cleaning of the melt bath is improved by the
positive proportion. The arc becomes wider and the penetration is less deep. The
use of a negative value that is as high as possible with a sufficient cleaning effect
is recommended (factory setting - 65%).
