Note: Before using the synergic program, the program had to be assigned to the user memory.
Note: The list of available programs depends on the power source.
Synergic GMAW-P (Pulsed MIG) welding is ideal for low
spatter, out of position. During pulse welding, the
welding current continuously switches from a low level to
a high level and then back again. Each pulse sends a
small droplet of molten metal from the wire to the weld
puddle.
Wire Feed Speed [32] is the main control parameter. As
the Wire Feed Speed is adjusted, the power source
adjusts the waveform parameters to maintain good
welding characteristics.
Trim [24] is used as a secondary control
– the Right
Display [19]. The Trim setting adjusts the arc length.
Trim is adjustable from 0.50 to 1.50. 1.00 is the nominal
setting.
Figure 10
Increasing the Trim value increases the arc length.
Decreasing the Trim value decreases the arc length.
Figure 11
When Trim is adjusted, the power source automatically
recalculates the voltage, current and time of each part of
the pulse waveform for the best result.
Additionally can manually set:

Burnback

Run-In WFS

Preflow Time/ Postflow Time

Spot Time

2-Step/4-Step


Wave Control [27]:

UltimArc™
UltimArc™ – for pulse welding adjusts the focus or
shape of the arc. In consequence of increasing
UltimArc™ Control value the arc is tight, stiff for high
speed sheet metal welding.

Adjust range: from -10 to +10
