Depending on the selected fuse, the safety cut-out limits the maximum currents of the se-
lected process. As a result, it is possible that welding can no longer occur at the saved op-
erating points if these were saved before selecting the fuse.
If welding is nevertheless carried out at one of these operating points, the power source
operates at the limit value of the selected fuse – the power limitation is active. The operat-
ing point should be re-saved in accordance with the power limitation.
