Wrong wire alloy or wrong wire diameter
Check the wirespool that has been inserted
Wrong wire alloy or wrong wire diameter
Check weldability of the base material
The shielding gas is not suitable for this wire alloy
Use the correct shielding gas
Unfavourable welding conditions: shielding gas is contaminated (by
moisture, air), inadequate gas shielding (weld pool „boiling", drau-
ghts), contaminants in the workpiece (rust, paint, grease)
Optimise the welding conditions
Welding spatter in the gas nozzle
Remove welding spatter
Turbulence caused by too high a rate of shielding gas flow
Reduce amount of shielding gas, recommended shielding gas quanti-
ty (l/min) = wire diameter (mm) x 10 (e.g. 16 l/min for 1.6 mm filler
wire)
Too large a distance between the welding torch and the workpiece.
Reduce the distance between the welding torch and the workpiece
(recommended: 10-15 mm)
Tilt angle of the welding torch is too great
Reduce the tilt angle of the welding torch
Wirefeed components have incorrect diameter
Use wirefeed components with correct diameter
