MIX AC
This parameter serves to set the AC wave percentage with respect to
the DC current output.
Consequences of a higher value:
-
Greater weld penetration.
- Less deformation.
- Faster creation of the weld pool.
- Reduced cleanliness of the workpiece.
- Loss of arc.
FUSIONE EXTRA
This parameter establishes the percentage of the positive current
wave (pickling) that is subtracted and added to the negative current
(fusion).
The following picture shows the positive wave interval ΔI that, if
subtracted and added to the negative wave, forms the new form of
broken line wave.
Consequences of a higher value:
-
Tighter arc.
- Greater weld penetration.
- Reduced pickling.
- Loss of arc.
- Less deformation of the electrode.
AC FREQUENCY
The picture below shows the example where the wave on the second
graph has a double frequency compared with the first.
Consequences of a higher value:
-
Arc concentration.
- Reduction of heat-affected zone.
- Slower melt speed.
AC BALANCE
This parameter establishes the positive wave vs. negative wave time
ratio.
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.
Consequences of a higher value:
-
Greater weld penetration.
- Less cleanliness.
ELECTRODE DIAMETER
The parameter optimizes the AC TIG welding arc strike on the basis
of the diameter of the chosen electrode.
