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!
5.3.6.7 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.
Figure 5-28
• Root welding for metal sheets and pipes in all positions
• Unalloyed and low-alloy steels as well as high-tensile fine-grained steels
• Manual and automated applications
