Summary of MIG/
MAG pulse syner-
gic welding
MIG/MAG pulse synergic
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.
