Tacking Function There is a tacking function on the power source.
When a period of time is set for the setup parameter tAC (tacking), the tacking function is
assigned to the 2-step and 4-step modes. The process of the operating modes remains un-
changed.
During this time, a pulsed welding current is available, which optimizes the merging of the
weld pool when tacking two components.
