Penetration Stabiliser - Fronius TPS 320i Operating Instructions Manual

Penetration stabi-
The penetration stabiliser is used to set the max. permitted change in the wire feed speed
liser
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.

The constant voltage control for constant arc length causes a reduction in the mean cur-
rent value and hence a smaller penetration (x
