Parameters of CMT characteristics
General
Ignition
In CMT processes, the ignition process is generally initiated with SFI (Spatter-Free Igni-
tion). Regardless of the CMT characteristic, subsequent ignition behaviour in the CMT pro-
cess is controlled by the following parameters:
NOTE!
The creation and editing of CMT characteristics is a complex task and
therefore a core skill of Research & Development. Special measurement technol-
ogy (e.g. a high-speed camera, oscilloscope) as well as extensive background
knowledge is required for the creation and editing of CMT characteristics.
The modification of CMT characteristics on-site simply optimizes the application
in question.

vd_ignition
Wire feed speed command value [m/min] before welding begins (-30 - +30)
-30
=
backward movement of the wire electrode at 30 m/min
+30
=
forward movement of the wire electrode at 30 m/min
I_ignition
Command value for the ignition current [A], set when welding begins. The ignition current
depends on the filler metal and wire diameter.
t_ignition
Length of time [ms] that the parameters Vd_ignition and I_ignition are active when weld-
ing begins.
0
=
no ignition current, no wire feed speed
99.98
=
max. duration for ignition current and wirefeed speed command value
U_hotstart
Parameter [V] for changing the arc length when welding starts
10
=
short arc
40
=
long arc
t_hotstart
The length of time [ms] that the change in the arc length is active when welding begins.
0
=
no change in the arc length
654.98 =
max. duration for the change in arc length
