Arc length stabilizer
The arc length stabilizer forces short arcs, advantageous for welding, via a short-circuit
current control and keeps them stable even with a variable stick out or external interfer-
ence.
The arc length stabilizer welding parameter is only available on the power source if the
WP PMC (Welding Process Pulse Multi Control) option has been enabled.
Unit - (effect of stabilizer)
Setting range 0.0 - 5.0
Factory setting 0.0
0.0 The arc length stabilizer is deactivated.
0.1 - 5.0 The arc length stabilizer is activated.
The arc length is decreased until short circuits start to occur.
Application examples
Arc length stabilizer = 0 / 0.5 / 2.0
Arc length stabilizer = 0
Arc length stabilizer = 0.5
Arc length stabilizer = 2
Activating the arc length stabilizer reduces the arc length until short circuits start to occur.
The frequency of the short circuits is controlled and kept stable.
Increasing the arc length stabilizer causes a further shortening of the arc length (L1 ==>
L2 ==> L3). The advantages of a short, stable and controlled arc can be used more ef-
fectively.
