3.1 Applications
3.1.1

MIG/MAG standard welding

Metal arc welding using a wire electrode, where the arc and the weld pool are shielded from the
atmosphere with inert (MIG) or active (MAG) gasses or gas mixtures.
3.1.1.1

forceArc

Low-heat, directionally stable and powerful high-performance arc with deep fusion penetration for the
upper power range Unalloyed, low-alloy and high-alloy steels as well as high-tensile fine-grained steels.
3.1.1.2

rootArc

Short arc with perfect weld modelling capabilities for effortless gap bridging, especially for positional
welding
3.1.1.3

coldArc

Heat-reduced, low-spatter short arc for high dimensional stability welding and brazing, plus root welding
with excellent gap bridging capabilities.
3.1.1.4

pipeSolution

Reduced-energy MAG welding. X-ray-proof welding of pipelines and pipework without lack of fusion. Root
pass and fill and final pass with or without air gap. Low- and high-alloy steels with solid wires.
3.1.2

MIG/MAG pulse welding

Welding process for optimum welding results when joining unalloyed, low-allow and high-alloy steels and
aluminium thanks to controlled droplet transfer and targeted, adapted heat input.
3.1.2.1

forceArc puls

Effective extension of the forceArc arc. Secure sidewall fusion, easy to model and control by the user.
Ideal for welding filler and final passes in all power ranges and positions.
3.1.2.2

rootArc puls

The perfect enhancement for focused heat input for the higher performance range
3.1.2.3

coldArc puls

The optimum enhancement for the higher performance range, with focused heat input exactly where the
heat is required.
3.1.3

TIG (Liftarc) welding

TIG welding procedure with arc striking by contact with the workpiece and subsequent removal of the
electrode.
3.1.4

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.
3.1.4.1

Air arc gouging

During gouging, an arc burns between a carbon electrode and the workpiece, heating the workpiece until
it is molten. At the same time, the molten metal is blown out with compressed air. Special electrode
holders with a compressed-air connection and carbon electrodes are required for gouging.
