Effects of excessively high voltage:
-
arc too long
-
scoring may appear around the weld seam
-
wire electrode may weld fast to the contact tube
Effects of excessively low voltage:
-
arc too short
-
The wire electrode is not sufficiently melted - heavy spatter due to wire electrode pen-
etrating the welding material
(16) d_Ip2
Parameters on the falling edge of the pulse
Linear pulsing current decrease rate
[A/ms]
0.1
=
no decrease in puls-
ing current
2200
=
maximum pulsing
current drop
(17) tau_Ip2
Non-linear pulsing current decrease
rate [ms]
I_p2
Droplet-detachment current [A]
(must be greater than I_base, other-
wise there is a risk of an arc break)
t_p2
Length of time [ms] that the droplet detachment current is active (0 - 50)
0
=
no droplet detach-
ment current
d_I_base
Linear droplet-detachment current decrease rate [A/ms]
0.1
=
no decrease in droplet-detachment current
2200
=
maximum droplet-detachment current decrease
tau_I_base
Non-linear droplet-detachment current decrease rate [ms]
(18) I_base
Current command value [A] during the base current phase
(19) vd_pulscycle
Wire feed speed [m/min] during the pulse cycle (0 - 45)
U_set_puls
This parameter specifies the voltage command value [V] for controlling the arc
length.
