characteristics that enable a wide range of materials to be processed in the most effective
way.

Summary of MIG/ MIG/MAG pulse synergic
MAG pulse syner-
gic welding MIG/MAG pulse synergic welding is a pulsed-arc process with controlled material transfer.
In the base current phase, the energy supply is reduced to such an extent that the arc is
only just stable and the surface of the workpiece is preheated. In the pulsing current phase,
a precise current pulse ensures the targeted detachment of a droplet of welding material.
This principle guarantees a low-spatter weld and precise working across the entire power
range, as unwelcome short circuits with simultaneous droplet explosion and uncontrolled
welding spatter are virtually eliminated.
Summary of MIG/ MIG/MAG standard synergic
MAG standard
synergic welding The MIG/MAG standard synergic welding process is a MIG/MAG welding process across
the entire power range of the power source with the following arc types:
Short circuit arc
Droplet transfer takes place during a short circuit in the lower power range.
Intermediate arc
The droplet increases in size on the end of the wire electrode and is transferred in the mid-
power range during the short circuit.
Spray arc
A short circuit-free transfer of material in the high power range.
