Weld Cycle Timing. The first of the following two timing diagrams illustrates
the sequence of events during the weld cycle for driving a single welding transformer with one
welding control. The second timing diagram illustrates the sequence of events during the weld
cycle for sequentially switching between four welding transformers using one welding control.
The single welding transformer timing diagram results from a SCAN = 0 setting on the Mode
Selection extension display screen (refer to Chapter 5 under Selecting the Welding Transformer).
The timing diagram for four welding transformers results from a SCAN = 4 setting on the Mode
Selection display screen. You select the scan interval time also with this display screen.
