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.
3.1.1.1 forceArc
Heat-reduced, directionally stable and powerful arc with deep penetration for the higher performance
range. Non-alloyed, low-alloy and high-alloy steels and high-tensile fine-grained steels
3.1.1.2 rootArc
Short arc with perfect weld modelling capabilities for effortless gap bridging and positional welding
3.1.1.3 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).
3.1.2
TIG (Liftarc) welding
TIG welding process with arc ignition by means of workpiece contact.
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.
3.1.3.1 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.
