Operation In SEAM Mode
In SEAM mode, this option offers the ability to switch from any schedule to any other schedule
on the fly. When the control is in the SEAM mode (

01), it will respond to any of the
available inputs and select the schedule requested by the input board signals. However, during
a seam weld, the control can be commanded on the fly to change heats as it welds. This allows
for extreme flexibility, since all 50 schedules can be selected automatically using a PLC or
other dedicated input means (see Multiple Pilot Operation).
For example, a part to be welded requires schedules 00 and 01. A second, larger part requires
schedules 10 and 11. The PLC can select schedule 00 before beginning the weld and switch to
01 whenever appropriate during the weld. It can just as easily select 10 before beginning the
weld, and switch to 11 whenever appropriate during that weld. Ultimately, the application dictates
the schedule selected.
