Seam modulation
Seam modulation can be used in applications where a change in current is required. Two Heat intervals are
repeated for the duration of the weld. The following example shows how this type of sequence may be
implemented.
Parameter Setting Description
Sequence timing
Presqueeze ms The time for the electrodes to close onto the work piece.
Squeeze ms The time between the initial application of the electrode force
and the first application of welding current
Main heat ms The main welding current is applied
Post-heat ms The post-heat welding current is applied
Hold ms Electrode force continues after the welding current has
finished
