GMAW (MIG) SYNERGIC WELDING
For each wire feed speed, a corresponding voltage is
preprogrammed into the machine. The nominal pre-
programmed voltage is the best average voltage for a
given wire feed speed, but may be adjusted to prefer-
ence. When the wire feed speed changes, the Power
Wave automatically adjusts the voltage level corre-
spondingly to maintain similar arc characteristics
throughout the WFS range.
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 pro-
portional to inductance. Therefore, increasing
UltimArc™Control greater than 0.0 results in a crisper
arc
(more
spatter)
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)

Preflow Time
Adjusts the time that shielding

pulled and prior to feeding.
Run-in WFS:
Run-In sets the wire feed
speed from the time the trigger
is pulled until an arc is estab-

Start Procedure
The Start Procedure controls
---
the WFS, Volts at a specified
---
time at the beginning of the
---
weld. During the start time, the
---
machine will ramp up or down
from the Start Procedure to the
preset Welding Procedure.

Spot Timer
Adjust the time welding will
continue even if the trigger
is still pulled. This option
has no effect in 4-Step
Trigger Mode.
Crater Procedure controls the
Crater Procedure
WFS and Volts for a specified
time at the end of the weld
after the trigger is released.
During the Crater time, the
machine will ramp up or down
from the Weld Procedure to
the Crater Procedure.
The burnback time is the
Burnback:
amount of time that the weld
output continues after the wire
stops feeding. It prevents the
wire from sticking in the puddle
and prepares the end of the
wire for the next arc start.
Postflow Time
Adjusts the time that shielding
gas flows after the welding out-
put turns off.
