Corrections dur-
ing welding
The arc length correction and arc-force dynamic parameters can be used to optimize the
welding result.
Arc length correction:
- = shorter arc, reduced welding voltage
0 = neutral arc
+ = longer arc, increased welding voltage
Pulse / arc-force dynamic correction
For continuous correction of the droplet detachment force in MIG/MAG pulsed synergic
welding
- reduced droplet detachment force
0 neutral droplet detachment force
+ increased droplet detachment force
For influencing the short-circuiting dynamic at the instant of droplet transfer during
MIG/MAG standard synergic welding
- = hard, stable arc
0 = neutral arc
+ = soft, low-spatter arc
SynchroPulse
welding
SynchroPulse is recommended for welded joints with aluminum alloys whose weld
seams should have a rippled appearance. This effect is achieved using a welding power
that changes between two operating points.
The two operating points result from a positive and negative change in the welding
power to a dFd (delta wire feed) value that can be adjusted in the Setup menu (delta wire
feed: 0.0 - 3.0 m/min or 0.0 - 118.1 ipm).
Other parameters for SynchroPulse:
- Frequency F of the operating point change (set in the Setup menu)
- Arc length correction for the lower operating point (set via the arc length correction
parameter on the control panel)
- Arc length correction for the higher operating point (set in the Setup menu, para-
meter Al.2)
To enable SynchroPulse, you must change at least the value of the F (Frequency) para-
meter from OFF to a variable in the range of 0.5 to 5 Hz in the process Setup menu.
NOTE!
SynchroPulse is not supported with standard manual welding selected.
