mains yet.
1. Connect the AC power input cable between the Power Supply AC220V 3 IN connector
and the 220 VAC, 3-phase power source as shown in Figure 3-1.
2. Interconnect the welding transformer and the Power Supply as shown in Figure 3-1. If
your application requires the use of multiple welding transformers, interconnect the
welding transformers with the Power Supply through the Transformer Selector as shown
in Figure 3-2.
3. Connect the Signal I/O cable between the Weld Head and the Power Supply I/O Connect-
or. The factory wiring of the Power Supply I/O connector allows the weld head firing
