forceArc
Heat-reduced, directionally stable and powerful arc with deep penetration for the upper power range.
Figure 5-16
• Smaller included angle due to deep penetration and directionally stable arc
• Excellent root and sidewall fusion
• Secure welding also with very long stick-outs
• Reduced
undercuts
• Un-, low- and high-alloyed steels as well as high-tensile fine-grained building steels
• Manual and automated applications

You can make use of these properties after selecting the forceArc process (see the "Selecting a
MIG/MAG welding task" chapter).
As with pulse arc welding, it is important to make sure of a good welding current connection.
• Keep welding current cables as short as possible and ensure that cable cross-sections are adequate!
• Fully unroll welding current cables, torche tube packages and, if applicable, intermediate tube
packages. Avoid loops!
• Use welding torches, preferably water-cooled, that are suitable for the higher power range.
• Use welding wire with adequate copper coating when welding steel. The wire spool should have layer
spooling.
NOTE
Unstable arc!
Welding current cables that are not fully unrolled can cause faults in the arc (flickering).
• Fully unroll welding current cables, torch tube packages and, if applicable, intermediate
tube packages. Avoid loops!
