5.2.9 rootArc/rootArc puls
Short arc with perfect weld modelling capabilities for effortless gap bridging, especially for root welding
Figure 5-25
• Reduced spatter compared to standard short arc
• Good root formation and secure sidewall fusion
• Manual and automated applications
Unstable arc!
Welding current cables that are not fully unrolled can cause faults in the arc (flickering).
• Fully unroll welding current cables, torch hose packages and, if applicable, intermediate hose
packages. Avoid loops!

5.2.10.2 Automatic cut-out
Once the fault periods have elapsed, the automatic cut-out stops the welding process when it has been
triggered by one of two states:
• During ignition
5 s after the start of the welding process, no welding current flows (ignition error).
• During welding
The arc is interrupted for more than 5 s (arc interruption).
