In the next example, solenoid valve 1 will be the standard valve and solenoid valve 2 will
be the forging valve. The total weld time is 15 cycles at 95 percent current with the forging
valve activated after 10 cycles.

For Forge during weld it is possible to select a percent current for the second schedule
different from that of the first schedule.

Other combinations of weld schedules may be combined to create other FORGING
schedules. For example it would be possible to use UP SLOPE in the first sequence and
Pulsation in the second sequence.
