Chapter 2: Resistance Welding
What is Capacitive Discharge Resistance Welding?
Capacitive discharge resistance welders, also called capacitive discharge or CD welders, utilize
internal capacitors to store energy. These capacitors are able to discharge large amounts of energy
very rapidly. The rapid discharge of energy is critical to forming the weld nugget. Formation of the
weld nugget occurs during the rst few milliseconds of the welding process. Sunstone’s proprietary
technology allows the energy to be discharged with very high peak currents, as seen in FIGURE 1
below, to produce the best weld nuggets.
This technology is not only designed to increase the energy delivered for weld formation but to
also minimize the heat that is spread to the surrounding material. This ‘heat-affected zone’ around
the weld can suffer from rapid heating and cooling from the weld. But with Sunstone’s proprietary
technology, this zone can be localized to just a small spot around the weld.
FIGURE 1: Sample capacitor discharge curve with high peak current.

Sunstone Welders User Manual: CDDP-A
WELD FORMATION
Spot welding relies on metal resistivity (resistance) to heat and fuse metal. A large current is passed
through the workpiece metal. Energy is dissipated due to metal resistance in the form of heat which
melts and fuses the weld materials. The welder must overcome both the contact resistance and the
bulk resistance of the material in order to begin the melting process.
FIGURE 2 below shows an example of a micro-scale surface prole. On the micro-scale, material
surfaces are rough and only contact in a limited number of locations. In the rst few milliseconds of
weld formation, the high-resistance metal bridges melt, allowing other bridges to come into contact
to continue the melting process. When all of the bridges have fused, the contact resistance is zero.
The bulk resistance of the metal then plays the nal role in the weld formation.
FIGURE 2: On the micro-scale, surface
roughness limits surface-to-surface contact.
More contact points result in a lower contact
resistance.
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 metal bridges
or contact points are formed (see FIGURE 2). Using more electrode pressure creates more metal
bridges. This results in a lower contact resistance and a cooler weld. Conversely, light electrode
pressure results in less metal contact, higher resistance, and a hotter weld. An appropriate amount of
pressure should be used to ensure good weld strength.
ELECTRODE CONFIGURATIONS
FIGURE 3 shows several electrode congurations used in resistance welding. FIGURE 3a is called
an opposed conguration. Current is passed from one electrode through both workpieces and out
an opposing electrode. FIGURE 3b shows a step electrode conguration. This conguration is
used when there is access to only one side of the workpiece and an electrode can be placed on
both materials. FIGURE 3c is a series or parallel conguration. Electrodes can only be placed on
one metal surface from one side. Current is divided between the two parts. This weld conguration
requires more weld energy.

WELD ENERGY
Sunstone capacitive dual pulse welders allow adjustment of the stored
energy via the touch screen user interface, shown in FIGURE 4. The
energy is then displayed in watt seconds (Joules) as a waveform
graph on the user interface LCD display. The Total Stored Energy
will change how much energy is stored in the internal capacitors and
directly corresponds to the peak current available. The energy of Pulse
1 and Pulse 2 can be changed independent of each other, but the Total
Stored Energy of Pulse 1 and Pulse 2 added together must be lower
than the Total Stored Energy. More information can be found on p.14 of
this manual.

Chapter 3: Setup
Pre Setup Information
VOLTAGE AND POWER REQUIREMENTS
Sunstone Advanced Capacitive Discharge Dual Pulse (CDDP-A) welders are equipped with universal
power supplies and can be used with either 110 or 220VAC. No voltage selection is required prior to
connecting and powering on the welder. The welder will detect the voltage, and make the appropriate
adjustments automatically.
WELD ACTUATION
The CDDP-A welders are actuated by means of an external trigger port located on the back of
the welder (see FIGURE 5). The trigger uses a 3 DIN (p.12) connector and requires shielded wire.
FIGURE 5 shows the proper pin placement for custom external trigger cables. The standard external
trigger cable connector is an SD-30LP made by CUI Inc.

Welder to Hand Held Attachment Setup
QUICK START SET UP OF HAND HELD ATTACHMENTS TO CDDP-A WELDERS
Sunstone Engineering manufactures a variety of welding hand pieces to accommodate a diverse
range of welding applications. Hand piece welding attachments allow ease of use and versatility.
1a. Turn off welder and unplug AC power cord for safety.
1b. Remove hand held attachment from its package.
12
2a. Single probe, dual probe, and tweezer hand held attachments - Connect
the hand held attachment cables to the negative and positive terminals on
the back of the welder, then connect the 3 pin actuation foot pedal cable to
the back of the welder.
2b. Pressure actuated hand attachments - Connect the hand held
attachment cable to either of the terminals on the back of the welder and the
grounding clip cable to the other terminal. Then attach the trigger cable to the
back of the welder.
3. Plug the welder power cable into an AC power outlet.
4. Turn the welder on and set the desired energy settings.
Roll Spot Setup
QUICK START SET UP OF CDDP-A ROLL SPOT HAND ATTACHMENT
Roll Spot is a function that allows users to perform a continuous string of welds for any prolonged
time period – for as long as the trigger signal is actuated. The Roll Spot function requires an
attachment that is specically designed for roll spot welding.
1a. Turn off welder and unplug AC power cord for safety.
1b. Remove the roll spot attachment from its package.
2. Connect the roll spot cable to the terminals on the back of the welder and the grounding clip cable
to the other terminal. Then attach the trigger cable to the back of the welder.
3. Plug the welder power cable into an AC power outlet.
4. Turn the welder on and set the desired energy settings.
5. Roll Spot mode can be turned on or off in the “Control” tab within the home screen.
a. In Roll Spot mode, the system has an adjustable “Welds per second” text entry box that
affects the frequency or rate of welding while a trigger signal is maintained.
b. In Roll Spot mode, both pulses can be used, but the comparator is disabled.
c. In Roll Spot mode, the device will continuously weld at an adjustable rate for as long as
the trigger signal is maintained. If using a foot pedal, the welder will continue to weld for as
long as the foot pedal is depressed. If using a pressure actuated hand piece, the welder will
continue to weld for as long as the pressure actuated switch is engaged.
d. In Roll Spot mode, two variables will affect the time between each weld. The rst is an
adjustable “welds per second” text entry box that can be set by the operator. The second factor
is the recharge time between welds. This is determined based on the energy setting. The
higher the weld energy, the longer the delay between welds will be.
e. When in Roll Spot mode, the operator can choose to use single or dual pulse. When dual
pulses are chosen, operator can change the “Delay Between Pulses” text entry box to adjust
the this delay to match the delay between welds.

Sunstone Welders User Manual: CDDP-A
Chapter 4: Operating Instructions
Pulse Control
DUAL PULSE WELDING
Sunstone dual pulse welders have two pulse width energy controls. Each pulse can be adjusted
separately or turned off 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 all 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.
USING THE DUAL PULSE WELD FUNCTION
Using multiple pulses increases weld quality. In dual pulse mode Sunstone welders will re twice
from a single actuation. The rst pulse is used to remove surface inconsistencies and contaminants
which helps to displace oils, break through oxide layers, and seat the welding electrodes.
FIGURE 15: This shows what the welder discharge curve would
look like when using the dual pulse setting as outlined above.
SETTING Pulse 1 AND 2
The Pulse 1 energy setting should be chosen such that the parts adhere weakly. To determine Pulse
1, turn off Pulse 2 and do a series of test welds starting at a low pulse energy setting. Increase the
pulse energy about 3% every test until the parts stick together to achieve maximum heat. Pulse 1
energy is typically below 10%. Pulse 2 energy is typically between 50% and 70%. A test weld should
be performed and pulled apart to determine weld strength. A nickel strip to nickel plated steel weld,
typically seen in battery pack manufacturing, should pull apart leaving holes in the thin nickel metal
and leaving the weld nuggets on the battery terminal. Thicker materials should be pulled with a
specic pull force requirement in mind.
ENERGY ADJUSTMENT
Each Sunstone welder is fully adjustable between its minimum and maximum energy. Sunstone
capacitive dual pulse welders have weld repetition rates of up to 650 welds/min. See Table 2 on page
37 for additional details on weld repetition rates. The weld energy text entry box can be used to set
14
the total welder energy storage and is also used to set the peak weld current. The pulse energies are
then adjusted to provide the appropriate weld energy released during each weld.
Timing Diagrams
D1: A delay that occurs from the time primary trigger is triggered and the signal to the weld head is
sent. Typical time for this is between 1 and 50 milliseconds.
D2: A delay that occurs from the time the weld head is engaged and when trigger 2 is triggered.
D3: A delay that occurs from the time the secondary trigger is triggered and the weld occurs. Typical
time for this is between 1 and 50 milliseconds.
Pulse 1: The duration of this delay is dependent on the energy programmed on welder for Pulse 1.
Cool: The duration of delay is dependent on the time programmed on welder for time between pulses.
User can select between 1 and 100 milliseconds. This time will be ignored if either pulse is disabled.
Pulse 2: The duration of this delay is dependent on the energy programmed on welder for Pulse 2.
D4: After this delay, alarms and warnings are sent. Typical time for this is between 1 and 50
milliseconds.
D5: After this delay the Weld Ready signal will return to a high position. This delay will depend on the
time needed to charge to the desired energy, but will typically be between 50 and 5000 milliseconds.

WELDER DATA SPECIFICATIONS
Cabling between welder and weld head is important in determining peak weld current and adjusting
weld pulse timing. Table 1 indicates peak currents that can be expected with 3 to 4 foot sections of
these cables. Typically, hand pieces will use 4 to 8 AWG wire while Weld Heads will be hooked up
with 2/0 or 4 AWG wire.
