WELDING HEAD
Select whether the welding head is to be the front HEAD or rear TAIL.
AC SYNC MASTER
One power source in a tandem system has to be set as ACsynchronization master if
synchronized ACwelding is used. Preferably the first ACwelding power source is set as
ACsynchronization master.
TRAVEL CONTROL
Select whether the welding head is control the travel. Both the front and rear welding heads
can control the travel, but only one at a time.
SYNCRONIZED WELD START
If ON is selected it means that one only need start the control unit for the front welding head.
The rear one is started automatically. If OFF is selected all the welding heads must be
started using the relevant control unit.
SYNCRONIZED AC WELDING
Synchronized AC welding means that the frequency and balance, the AC pulses, are
synchronized to the same values for all welding heads in the tandem system.
WELD HEAD OFFSET
WELD HEAD OFFSET is the distance in millimetres between the welding heads. The weld
head offset should always be set, whether a synchronised welding start is selected or not. If
a non-synchronised welding start is selected, the offset is used to calculate a timedelay for
the welding start on the TAIL welding head.
