Adjusting inductance. This can be selected using pushbutton DG. This function
can be used to switch between a narrow, hard arc with deep penetration (negative
values) and a broad, smooth arc (positive values). The adjustment can range
between +/- 9.9, 0 is the factory setting.
Adjusting arc length. This can be selected using pushbutton DH. If necessary, arc
length (welding voltage) can be corrected by +/- 9.9 V for the specifi c welding job,
0 is the factory setting.
Press pushbutton (DF) on the display and it
becomes possible to activate the function using
the ON pushbutton, which turns orange when
pressed.
Active in synergic MIG/MAG processes only.
This mode involves changing wire speed (and
consequently also current intensity) between two
levels. Before setting double level welding, make a
short bead to determine the wire speed and hence
the current to obtain the optimum bead penetration
and width for the type of weld to be performed. In
this way the wire feed speed is determined; the set
SPEED DIFFERENCE parameter will be added to
or subtracted from this value. Before start working
you should not forget that for a correct bead, the
minimum overlap between one mesh and another
must be 50%.
