50% of balance means that the 2 alternating positive and negative are equal.
Balance can be adjusted from 20% to 60% (cleaning).
In order to maintain a sharp tungsten it is better to use a shorter cleaning time
The balance is pre-adjusted to 40% (cleaning 40% - penetration 60%), which is a good solution
between the 2 modes and allow aluminium welding in almost all the cases.
Z
Select tungsten electrode
Place a tungsten electrode pure or DLZ (Itrium Lanthane Zirconium) or lanthane, without radiation.
For low current, use the smallest diameter possible.
For very low current (3A to 15A), use only grinded tungsten electrode
