SUNSTONE CDDP-A USERS GUIDE
Control
The Control tab is used to control the weld held actuation and timing. There are two sections on the Control tab:
Weld Head Control and Roll Spot Control.
WELD HEAD CONTROLS
When connected to a Sunstone weld head, the CDDP-A can be connected in three dierent scenarios:
Scenario 1: Primary trigger actuates weld head. Secondary trigger triggers weld energy release.
Fully Manual allows the weld head descent and the weld energy release to trigger independently, commonly
referred to as a “two pedal system.” The rst pedal controls the weld head descent, and the second signals the
welder to release energy. The Squeeze Time and Hold Time inputs are disabled in Fully Manual mode.
Scenario 2: Primary trigger initiates weld sequence.
Auto With Timing is used when the entire weld process is initiated with one single pedal. Squeeze Time and
Hold Time are important and need to be congured for this mode to work correctly. Pressing the pedal will
begin the process. The squeeze time controls the time between when the pedal is pressed and when the weld
energy is released. Make sure that the squeeze time is long enough to allow weld head to descend and apply
pressure to the work piece. The Hold Time determines how long the weld head stays descended after the weld
energy is released. Once the hold time is met, the weld head will ascend back up to its starting position. See the
Sunstone weld head users guide for more information.
Scenario 3: Primary trigger initiates weld sequence.
Auto With Trigger is used when the entire weld process is initiated with one single pedal. However, Squeeze
Time is not used. Instead, the internal trigger switch inside the weld head will send the weld energy release
signal once the weld head reaches a predetermined force on the work piece. Hold time is used in this mode to
control how long the weld head stays descended after the weld energy is released. See the Sunstone weld
head users guide for more information.
ROLL SPOT CONTROL
Roll Spot Control is used in conjunction with a weld head or hand piece equipped with a welding wheel. To use
roll spot, enable the roll spot button, and then set the welds per second input to the desired number. At higher
powers, the welder can require additional time to recharge after each well, so the maximum welds per second
rate may be limited. See the Sunstone weld head users guide for more information.
Note: The Comparator will be disabled while Roll Spot is enabled.
Each power supply is equipped with a part check feature that will verify a part is in place prior to releasing
energy. This is an important feature in automated environments where an operator is not visually ensuring
each part is properly placed. In order for Part Check to work as intended a Total Stored Energy must be set to a
minimum of 50WS for CD1200DPA, 25WS for CD600DPA, 20WS for CD400DPA, or 15WS for CD200DPA.
