Parameters of pulse characteristics
Ignition
Ignition current
Strength of ignition current [A] set when welding begins. The ignition current depends on
the filler metal and wire diameter.
- In the case of low ignition current, the welding wire is not sufficiently preheated or
burned
- In the case of high ignition current, the filler wire is excessively preheated or burned
Pulsing parame-
ters
Overview of the pulsing parameters
Feeder creep speed
Wire feed speed [m/min] before welding begins (0 - currently set wire feed speed)
Ignition current time
The length of time [ms] the ignition current set when welding begins is active.
0 = no ignition current
40 = max. duration for ignition current
(1) Pulsing current time (6) Droplet detachment current
(2) Droplet-detachment time (7) Current rise when pulsing begins
(3) Current-rise (tau) (8) Ground current
(4) Current drop when pulsing ends (9) Pulse current
(5) Tau current drop
