With energy in a stored state, your Sunstone CDDP welder pro-
vides control over how the energy is released. The typical ca-
curve. But with adjustments to your welder’s controls, you will
be able to control how much energy is released in two pulses.
See Chapter 3 on page 10 for more information.
Weld Formation
Spot welding relies on metal resistivity (resistance) to heat and
fuse metal. A large current is passed through the work piece
metal. Energy is dissipated due to metal resistance in the form
of heat which melts and fuses the weld materials. There are two
phases to the melting process. The welder must overcome both
the material contact resistance and the bulk resistance of the
material.
On the micro-scale, material surfaces are rough and only con-
metal bridges melt, allowing other bridges to come into contact
to continue the melting process. When all of the bridges have
Tips
WELD PRESSURE
Several other factors play a part in the contact resistance. The
larger the contact resistance the hotter the resultant weld.
On the micro-scale, contact resistance is reduced when more
-
ing more electrode pressure creates more metal bridges. This
results in a lower contact resistance and a cooler weld. Con-
versely, light electrode pressure results in less metal contact,
higher resistance, and a hotter weld. An appropriate amount of
pressure should be used to insure good weld strength.

Weld Head Setup
Sunstone manufactures a variety of weld heads to accom-
modate a diverse range of welding applications, as shown in
Figure 7.1. Both the parallel and opposed Sunstone weld head
provides a great amount of control and precision. Follow these
abbreviated instructions to connect a weld head to the CDDP.
• Remove the weld head from the box and place it on a
secure work surface.
• Attach the weld head cables to the negative and posi-
tive terminals (see (C) in Figure 6.1).
• For operating the weld head manually, see the weld
head users guide for setup.
• For operating the weld head pneumatically, see the
weld head users guide for setup.
• Turn the welder on, assure the weld head is actuating,
then set the desired energy setting. See Chapter 3 on
how to select desired energy settings.
Note: See weld head user manual for more precise setup infor-
mation.
Hand Held Attachment Setup
Sunstone Engineering manufactures a variety of welding hand
pieces to accommodate a diverse range of welding applica-
tions. Hand piece welding attachments allow ease of use and
versatility. Follow these instructions to connect a hand held

How to Adjust Energy
Each Sunstone welder is fully adjustable between its minimum
and maximum energy. Sunstone capacitive dual pulse welders
have weld repetition rates of up to 600 welds/min. See table on
The Weld Energy knob (D) is used to set the total welder en-
ergy storage and is also used to set the peak weld current. The
pulse widths are then adjusted to provide the appropriate weld
energy released during each weld.
How to Use Pulse Controls
Sunstone dual pulse welders have two pulse width energy
