Activarc - EWM Tetrix 352 Synergic Operating Instructions Manual

5.2.21 activArc

The EWM activArc process, thanks to the highly dynamic controller system, ensures that the power
supplied is kept virtually constant in the event of changes in the distance between the welding torch and
the weld pool, e.g. during manual welding. Voltage losses as a result of a shortening of the distance
between the torch and molten pool are compensated by a current rise (ampere per volt - A/V), and vice
versa. This helps prevents the tungsten electrode sticking in the molten pool and the tungsten inclusions
are reduced.
