6.1.5 rootArc XQ / rootArc pulse XQ

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

Figure 6-15

•  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!
