GMAW (MIG) SYNERGIC WELDING
In synergic welding modes, WFS is the dominant control
parameter. For each wire feed speed, a corresponding volt-
age is programmed into the machine at the factory. The
user adjusts WFS according to factors such as wire size,
material thickness, penetration requirements, etc. The
Power Wave then uses the WFS setting to select the appro-
priate voltage. The voltage selected will be a nominal volt-
age. The user can adjust the voltage higher or lower to
compensate for material condition or individual preference.
UltimArc™Control, adjusts the apparent inductance of the
wave shape. The UltimArc™Control adjustment is similar to
the "pinch" function in that it is inversely proportional to
inductance. Therefore, increasing UltimArc™Control
greater than 0.0 results in a crisper arc (more spatter) while
decreasing the UltimArc™Control to less than 0.0 provides
a softer arc (less spatter).

Synergic CV programs feature an ideal voltage best
suited for most procedures. Use this voltage as a
starting point and adjust if needed for personal prefer-
ences.
When the voltage knob is rotated, the display will
show an upper or lower bar indicating if the voltage is
above or below the ideal voltage.
• Preset voltage above ideal
voltage. (upper bar displayed)
• Preset voltage at ideal
voltage. (no bar displayed)
• Preset voltage below ideal
voltage. (lower bar displayed)
