If the Feeder inching button is released and pressed again before one second has
elapsed, the sequence starts again from the beginning. This makes it possible to position
the wire continuously at the low wire feed speed of 1 m/min or 39.37 ipm when neces-
sary.
bbc
Burn-back time correction
Unit s
Setting range ± 0.20
Factory setting 0
F
Frequency - for SynchroPulse option
Unit Hz
Setting range OFF or 0.5 - 5
Factory setting OFF
NOTE!
In order to activate SynchroPulse, you must (as a minimum) change the value of
the parameter F (frequency) from OFF to a value of between 0.5 Hz and 5Hz.
The parameters and the function of SynchroPulse are explained in more detail in the
MIG/MAG welding section.
dFd
delta Feeder - Welding power offset for the SynchroPulse option (defined by the wire
feed speed)
Unit m/min ipm
Setting range 0.0 - 2.0 0.0 - 78.74
Factory setting 2.0 78.74
AL.2
Arc length correction 2 (for the upper operating point of the pulsed welding power with
the SynchroPulse option)
Unit % (of welding voltage)
Setting range ± 30
Factory setting 0
NOTE!
The arc length correction for the lower operating point is made using parameter
AL.1.
ALS
Arc length start - Increased welding voltage as striking voltage at welding startup, for
MIG/MAG standard synergic welding. In conjunction with the Alt parameter explained
below, ALS makes an optimised ignition sequence possible.
