Root Weld is an energy-reduced, controlled MIG/MAG short arc which is suited for the special requirements of root welding or thin plate welding. where out-of-position welds and varying gap widths often arise. Compared to the standard short arc, Root Weld is considerably quieter and produces less spatters.. Due to the improved process control, Root Weld is more stable and can thus be perfectly controlled even in the lower capacity range.. With Root Weld you reduce the workpiece distortion because of the lower heat input. You avoid extensive reworks due to the minimised spatter formation. You always achieve optimum welding results as the arc is resistant to external influences. Do you also want a stable welding process for excellent welding quality even under demanding conditions? Then rely on Root Weld by CLOOS!
