Parameters of CMT/Pulsed Advanced characteris-
tics
General
Ignition
In CMT processes, the ignition process is generally initiated with SFI (Spatter-Free Igni-
tion). The subsequent ignition behaviour in the CMT process is controlled by the following
parameters:
Hotstart
NOTE!
The creation and editing of CMT/pulse characteristics (CMT+P) is a com-
plex task and therefore a core skill of Research & Development. Special meas-
urement technology (e.g. a high-speed camera, oscilloscope, etc.) as well as
extensive background knowledge is required for the creation and editing of
CMT+P characteristics.
The modification of CMT+P ADV characteristics on-site simply optimizes the ap-
plication in question.
slaghammer On_1/Off_0
Function for removing slag at the end of the wire electrode
The wire electrode carries out a quick forward and reverse movement and touches the
surface of the workpiece until any slag drops off the wire electrode and ignition occurs.
The ignition parameter for aluminium is slaghammer = 0.
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
I_sc_wait
Current command value [A] following the boost phase until the dipping of the wire elec-
trode into the weld pool
t_hotstart
The length of time [ms] that the change in arc power is active when welding begins.
0
=
no change in the arc length
650
=
max. duration for the change in arc power
