Seam pre-heat
Pre-heat can be used in applications where the initial current needs to be different to the main current. The
following example shows a continuous seam weld with a pre-heat.
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
Pre-heat ms The pre-heat welding current is applied
Main heat ms The main welding current is applied
Hold ms Electrode force continues after the welding current has
finished
