Figure 6-8. Laser Output, Single Shot
Applying Multiple Weld Schedules (continued)
There is a difference of 50 volts between VOLT A and VOLT B for Schedule 1. The graph in
Figure 6-7 shows that the discharge cycle time is 5.5 seconds minimum.
In the case of waveform control, as shown in Figure 6-9, the schedules are set up such that:
Schedule 2 Voltage
VOLT
Schedule 4 Voltage
VOLT
FLASH1 450
A
FLASH1 420
A
FLASH2 350
B
FLASH2 300
B
When controlling the waveform with two voltages, check the difference between VOLT A and
VOLT B, then set the lower discharge cycle.
