Application examples
Penetration stabilizer = 0 m/min (not activated)
Penetration stabilizer = 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 current
value and hence a smaller penetration (x
2
).
Penetration stabilizer = n m/min (activated)
Penetration stabilizer = n m/min (activated)
Specifying a value for the penetration stabilizer ensures a constant arc length without large
current variations if the stick out is changed (s
1
==> s
2
).
The penetration (x
1
, x
2
) remains virtually unchanged and stable.
Penetration stabilizer = 0.5 m/min (activated)
