Current command value
a) reference current value for Q-Master values
b) current command value for operating the power source with constant welding current
in CC/CV mode
Unit
[A]
Range min. - max.
Current decrease
With a standard arc, the current decrease parameter determines the speed at which the
short circuit current control changes to voltage control.
Unit
-
Range 0 - 65535
Current decrease when pulse ends
The parameter describes the linear decrease of the current when pulsing ends.
Unit
[A/ms]
Range 0 - 1000
Current guideline value
in MIG/MAG standard manual welding, the current guideline value is normally determined
by trial and error or by performing a test weld; it has no influence on the welding param-
eters
Unit
[A]
Range 0 - max.
Current-rise
With a standard arc, the current rise parameter determines the speed at which the weld-
ing current increases for the duration of the short circuit.
Unit
-
Range 0 - 65535
Current-rise when pulse begins
The characteristic parameter describes the linear increase of the current when pulsing
begins.
Unit
[A/ms]
Range 0 - 1000
Current-rise (short circuit)
The parameter describes how the current is ramped up in the case of a short circuit.
Unit
[A/ms]
Range 0 - 1000
Current-rise (tau)
time of transition from a linear slope to the pulse current
Unit
[ms]
Range 0 - 5
d_boostdown
for setting the linear current decrease rate following the boost phase for CMT character-
istics
Unit
[A/ms]
Range 0 - 1000
d_boostup
for setting the linear current rise rate at the start of the boost phase for CMT characteris-
tics
Unit
[A/ms]
Range 0 - 1000
