Pulse Settings
Click on the Pulse Settings Tab to set energy release values per
pulse. The Pulse Settings Tab is the default selection.
Total Stored Energy
The Total Stored Energy value (A), as shown in Figure 14.1,
determines the initial peak value of the weld energy. The total
stored energy will determine the maximum amount of energy
that could be delivered in one weld. However, operators may
choose to not use 100% of the maximum stored energy. The
total energy can be set to 100% of the welders total available
energy, yet the pulse 1 and pulse 2 energies do not need to
equal the total stored energy value.
For example, Total energy can be set to 100Ws, Pulse 1 can be
set to 5Ws, and Pulse 2 can be set to 20Ws. The actual weld
energy delivered is only 25Ws (5+20), even though the total
stored energy is set to 100Ws.
Higher Total Stored Energy amounts will lead to welds with
more ‘punch’ because of the higher peak voltages. The example
scenario mentioned above (Total Stored Energy of 100Ws,
Pulse 1: 5Ws, Pulse 2: 20Ws) will have more initial ‘punch’ than
a weld with Total Stored Energy of 25Ws, Pulse 1 of 5Ws, and
Pulse 2 of 20Ws.
Pulse 1 and Pulse 2
Sunstone dual pulse welders have two pulse width energy
controls. Each pulse can be adjusted separately or turned o if
desired. Pulse 1 is adjustable between 0.1WS and 30% of Total
Stored Energy. Pulse 2 is adjustable between 0.1WS and 100%
of Total Stored Energy. In order for Pulse 2 to use 100% of the
Total Stored Energy, Pulse 1 must be disabled. When Pulse 1
is enabled, Pulse 2 can only use the remaining Total Stored
Energy (Pulse 2 Maximum Energy equals Total Stored Energy
minus Pulse 1 Energy).
Using multiple pulses can increase weld quality. In dual pulse
mode, Sunstone CDDP-A welders will discharge two separate
times with each weld trigger/initiation. The rst pulse is de-
