6.05.02 AC-SOFT Mode
When AC-SOFT mode is selected, there are two waveform options, a sinusoidal waveform or a
triangular waveform. When the internal parameter P24 is set to the "OFF" condition, the AC-SOFT
mode will output a sinusoidal waveform.
<Sinusoidal Wave (Set Internal parameters P24 to OFF) >
When AC-SOFT mode is selected, there are two waveform options, a sinusoidal waveform or a
triangular waveform. When the internal parameter P24 is set to the "ON" condition, the AC-SOFT
mode will output a triangular waveform.
<Triangular Wave (Set Internal parameters P24 to ON)>
See Section 4.7 in the Owner’s Manual for instructions on how to switch from AC-Soft sinusoidal
to AC-SOFT triangular waveform. Set Internal Parameter 24 to “ON” for Triangle Wave. Turn
Internal Parameter 24 to “OFF” for Soft AC.

AC-sinusoidal wave includes all the
benefits of AC- square wave with the
addition of maximum puddle control
and good wetting action of the weld
puddle which helps to overcome surface
tension.
AC-triangle wave provides the punch of
the peak amperage, while reducing
overall heat input. Quick puddle
formation reduces weld time — limiting
heat input and reducing weld distortion,
especially on thin materials.
