Fronius TPS 600i - Process Parameters for Process Control; Penetration Stabiliser

EN
Process parame-
ters for process
control
The following process parameters can be set and displayed for the process control:
- Penetration stabiliser
- Arc length stabiliser
- Combination of penetration stabiliser and arc length stabiliser
Penetration stabi-
liser
The penetration stabiliser is used to set the max. permitted change in the wire feed speed
to ensure that the welding current and hence the fusion penetration is kept stable or con-
stant with variable stick out.
The penetration stabiliser parameter is only available when the WP PMC (Welding Pro-
cess Pulse Multi Control) or WP LSC (Welding Process Low Spatter Control) option has
been enabled on the power source.
Unit m/min (ipm)
Setting range 0 - 10.0
Factory setting 0
0 The penetration stabiliser is not activated.
The wire feed speed remains constant.
0.1 - 10.0 The penetration stabiliser is activated.
The welding current remains constant.
Application examples
Penetration stabiliser = 0 m/min (not activated)
Changing the contact tube distance (h) alters the resistance in the welding circuit due to
the longer stick out (s
2
).
The constant voltage control for constant arc length causes a reduction in the mean cur-
rent value and hence a smaller penetration (x
2
).
