Applications
3.1.1
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.
3.1.2
TIG (Liftarc) welding
TIG welding procedure with arc striking by contact with the workpiece and subsequent removal of the
electrode.
3.2
Machine variants
3.2.1
Voltage reduction device
– VRD machine version
To increase safety, particularly in hazardous environments (like shipbuilding, pipe construction or mining),
the machine is equipped with the VRD (Voltage-reducing device)
voltage reduction device.
The VRD signal light is illuminated, when the voltage reduction device is operating without fault and the
output voltage is reduced to a value specified in the relevant standard (see technical data). The voltage
reduction device is only active on VRD machine versions.
