3.1

Applications

3.1.1

MIG/MAG standard welding

Metal arc welding using a wire electrode whereby gas from an external source surrounds the arc and the
molten pool to protect them from the atmosphere.
3.1.2

MIG/MAG cored wire welding

Welding with cored wire electrodes consisting of a metal casing and a powder core.
As with MIG/MAG standard welding, the arc is protected from the atmosphere by shielding gas. The gas
is supplied either externally (gas shielded cored wires) or produced in the arc by means of the powder
core (self-shielding cored wires).
3.1.3

MMA welding

Manual arc welding or, for short, MMA welding. It is characterised by the fact that the arc burns between
a melting electrode and the molten pool. There is no external protection; any protection against the
atmosphere comes from the electrode.
3.1.4

Air arc gouging

During air arc gouging, bad welding seams are heated with a carbon electrode and then removed with
compressed air. Special electrode holders and carbon electrodes are required for air arc gouging.
3.1.5

Voltage reducing device (VRD)

To increase safety, particularly in hazardous environments (like shipbuilding, pipe construction or mining),
the machine is equipped with the VRD (Voltage-reducing device) .
The VRD signal light is illuminated, when the voltage reducing device is operating without fault and the
output voltage is reduced to a value specified in the relevant standard (see technical data).
