Simultaneous welding on both sides, synchronisation types
This function is important, if two power sources are used to simultaneously weld on both sides, as is
sometimes required for welding thick aluminium materials in the PF position. This ensures that, with
alternating currents, the positive and negative pole phases are present on both power sources
simultaneously, thus avoiding the arcs negatively influencing each other.
5.16.1
Synchronisation via mains voltage (50Hz / 60Hz)
NOTE
This application relates to two types of synchronisation:
• Synchronisation between a Tetrix series machine and a competitor machine.
• Synchronisation between two Tetrix series machines.
Phase sequences and rotating fields of the supply voltages must be identical for both
welding machines.
If this is not the case, the energy input into the weld pool will be negatively affected.
Use the "Phase sequence changeover“ rotary switch to correct the phase difference in steps of
60° (0°, 60°, 120°, 180°, 240° and 300°).
An optimum phase correction will directly achieve better welding results.
