Section 12 Configuration 56
Seam pulsation
Seam pulsation can be used in applications where a continuous weld is not required. The Main heat and the
Cool2 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
Cool2 ms The material is allowed to cool with electrode force applied
Hold ms Electrode force continues after the welding current has
finished
Current control
Main mode P/W – CCu – CCC Operating mode of the Main heat interval
Main heat % The % heat used during the Main heat interval
Main current kA The current used during the Main heat interval
Main monitor
1
yes/no The current can be tested between limits
Low limit 1 % Current low limit
High limit
1
% Current high limit

1 The Main heat – Cool2 intervals are repeated until the Start input is removed.
2 The operation of the motor output is determined by the 2 nd stage test (Section 12 Configuration ).
