2. Features
The WELTOUCH CY-210D is a constant/alternating-current resistance weld control with a
15-schedule setting function.
It is controlled by a microcomputer, allowing it to be applied to all types of welding. Due to the
plating-layer treatment by the pre-stage current, heat treatment by the post-stage current, etc.,
splashing is prevented, the welding tip is protected from overheating, and an ideal welding
current can be set.
In addition, the CY-210D can be applied to all types of spot-welding machines by selecting
the secondary- or primary-current feedback constant-current control and source-voltage
fluctuation compensation method. The required items can be set very simply and easily.
The CY-210D has a wide range of features, as explained below.
1) Indicates the welding current, schedule set No., set time, etc. with an LED
2) Stores up to 15 schedules according to the materials and thicknesses of the
workpieces to be welded
3) Equipped with the 3-stage power-on system, and upslope and downslope
functions
4) Supplies a stable welding current by the primary and secondary constant-current
control method and source-voltage fluctuation compensation method
5) Has the welding mode applied to the high-tensile steel plate with a high initial
resistance
6) Includes functions for monitoring the current and conduction angle
7) Comes with a cover to protect the touch panel from oil mist

4. Connection
(1) Basic Configuration
1) The general system configuration of the CY-210D is as follows:
①CY-210D
The body of the constant-current resistance welding control. Connect AC
power to it.
②Thyristor contactor (Option)
Connects a welding power source to this device.
③Toroidal coil (Option)
Installed to the arm of the welding head. This is unnecessary in the primary
constant current control.
④Connecting cable (Option)
Connects the controller to the welding-robot controller
⑤Welding robot
An articulated robot. Prepare it separately.
2) Precautions for installation
①Confirm that the control is installed (fixed) securely at the specified
locations.
②Confirm the welding power source. The voltages for this device are
indicated below the terminal block.
③Ground the control securely.

(2) Connection of Power Source
1) Connect the power source to the power-supply terminal block mounted on the rear
panel.
①Connect the thyristor contactor to the power-supply terminal block on the
rear panel of CY-210D, as shown below.
②Securely connect each wire. Take care not to confuse the Nos. of the wires.
③Connect 02/(02) to the terminal for the voltage being used.
The connection of 01, (02) or 02 is important for the operation of the thyristor.
If it is connected improperly [if 01 and (02) or 02 are connected inversely], the
thyristor cannot be conductive. It must therefore be connected properly and
securely.
When no power-supply error is detected and the current does not flow even
though the power is supplied correctly and CY-210D starts normally, make
sure that 01 and (02) or 02 are not connected inversely.
④Be sure to ground the control.
Ground the E terminal (grounding) of CY-210D in common with the
grounding of the thyristor contactor.
Note: The thyristor contactor, welding transformer, welding head, and
connecting cable are optional.

②Set dip switch DSW1-(2) to the OFF position (see page 4-7).
③Precautions on installation of the toroidal coil
If the toroidal coil is broken in the constant-current control mode, no
power-supply error is detected and the operation stops. A proper installation
position must therefore be selected for the toroidal coil so that it will not be
broken by the temperature rise of the conductor, mechanism motion,
contact with a workpiece, or the like. In addition, secure the toroidal coil to
the conductor using a band, etc. If the toroidal coil is wound onto the
conductor as shown in Fig. 4-A, an error occurs. Accordingly, wind it as
shown in Fig. 4-B.
Note: No power-supply error is detected in the source-voltage fluctuation
compensation control mode.
Note: The thyristor contactor, welding transformer, welding head, and
connecting cable are optional.

④Checking for breakage and short-circuiting of the toroidal coil
Breakage of and shorts in the toroidal coil can be checked using a tester, as
the toroidal coil has the internal resistance shown in Fig. 5.
(Keep in mind that the internal resistance changes depending on the type of
toroidal coil.)
Toroidal coil Internal resistance
MB-400L 35–65
MB-45F 130–165
Fig. 5 Internal resistance of toroidal coil
The sensitivity of each toroidal coil is adjusted so that it will detect the current
accurately. If the cable is cut halfway and extended, or if the connector is
disassembled, the current cannot be kept constant. (When using the
toroidal-coil remote, use a special extension cable.)
2) Installation Method for a CT Coil
①Install a CT coil to the primary side of the welding transformer.
CT coil
Welding power supply
Welding transformer
Welding head
Thyristor contactor
②Set dip switch DSW1-(2) to the ON position (see page 4-7).
③Precautions on use of a CT coil
Use a CT coil with a rated primary current of 600 A and a secondary current
of 5 A. Connect a resistor of 0.2 10 W to its secondary side, then connect
both ends to the CY-210D using special connector 14-2A (manufactured
by KOMINE MUSEN ELECTRIC CORPORATION).
Note: The thyristor contactor, welding transformer, welding head, and
connecting cable are optional.
Note: The model number of connector is subject to change without notice.
Depending on the part to be changed, the mounting screw shape
may change and a necessary tool may be different. For the latest
parts information, contact a nearest sales office.

3) Explanation of functions of dip switches
①DSW1-(1) Selects the constant-current control or source-voltage
fluctuation compensation control.
OFF: Constant-current control
ON: Source-voltage fluctuation compensation control
②DWS1-(2) In constant-current control mode (DSW1-(1): OFF)
OFF: Constant-current control method with
secondary-current feedback
ON: Constant-current control method with
primary-current feedback
In source-voltage fluctuation compensation control mode
(DSW1-(1): ON)
OFF: Secondary-current feedback detection mode. By
connecting a toroidal coil, the measured value of the
welding current can be indicated and full-wave
errors can be detected.
ON: Primary-current feedback detection mode. By
connecting a CT coil, the welding current can be
measured and full-wave errors can be detected.
When using the primary-current feedback detection
mode, set the turn ratio of the transformer so that the
current can be measured properly (see page 6-11).
③DSW1-(3) Select the signal to be output to Pin 23 in the terminal block
on the rear panel.
OFF: Output of power-on timing signal
ON: Output of flicker
If this dip switch is set to OFF, the power-on timing signal is
output after Weld I starts and continues to be output until
Weld III finishes, regardless of the setting of Weld ON/OFF.
If this dip switch is set to ON, the flicker signal is output
only during power-on in Weld I, Weld II, and Weld III. The
power-on timing signal and the flicker signal are output
from the power-on signal [WELD ON].
④DSW1-(4) Sets the start-signal parity-check function when the
controller is started up in 15-schedule mode.
OFF: Parity check will not be executed.
ON: Parity check will be executed.
If this dip switch is set to OFF, the parity check will not be
executed. If it is set to ON, the parity check will be
executed, and a start-input error signal (Error code [02])
will be output if a parity error is detected. Odd parity is
checked. For details, see "(5) Input Method for Start
Signals, 2)" on page 4-11.
⑤DSW1-(5) Selects the self-holding timing for the start signal.
OFF: Self-holding of start signal at weld start
ON: Self-holding of start signal at squeeze
If this dip switch is set to OFF, the start signal is held when
the welding (Weld I) starts. If it is set to ON, the start signal
is held when the initial weld force (Squeeze) starts.

CY-210D
4.Connection
4-8
⑥DSW1-(6) Makes settings so that the power will or will not be supplied again
when the lower current limit is detected or no current flows.
OFF: Re-power-on---OFF
ON: Re-power-on---ON
If this dip switch is set to OFF, power is not supplied again.
If it is set to ON, current increased by 5% is supplied (see
4) on page 5-7).
Note: This does not apply in the source-voltage fluctuation
compensation control mode.
⑦DSW1-(7) Selects the length of time for which the holding finish signal is
output.
OFF: Output of holding-finish-signal level
ON: Output of holding-finish-signal pulse
If this dip switch is set to OFF, the holding finish signal is
output for approximately 0.2 seconds or while the start
signal is input. If this dip switch is set to ON, the holding
finish signal [HOLD END] is output for 0.2 seconds.
⑧DSW1-(8) Selects the action to be taken in the event of a current-monitor
error.
OFF: When there is a problem with the current monitor, a
holding finish signal is output and welding can be
started again.
ON: When there is a problem with the current monitor, a
holding finish signal is not output and welding cannot
be started again.
Note: This does not apply in the source-voltage fluctuation
compensation control mode.
⑨DSW2-(1) Selects the pulsation function or repeating function.
OFF: Pulsation function
ON: Repeating function
If this dip switch is set to OFF, the pulsation function is
selected and the [PULSATION (OFF)] key on the panel is
used to set the number of pulsations (see 1) on page 5-4).
If this dip switch is set to ON, the repeating function is
selected and the [PULSATION (OFF)] key on the panel is
used to set the off-time in the repeating mode (see 2) on
page 5-5).
⑩DSW2-(2) Selects the interlock function or weld-count monitor function.
OFF: Interlock function
ON: Weld-count monitor function
If this dip switch is set to OFF, the interlock function is
selected. In this case, the INTERLOCK/WELD No.SET is
used to input the interlock signal [INTERLOCK], and the
INTERLOCK/WELD No.ERROR is used to output the
interlock signal [INTERLOCK] (see 3) on page 5-6).
If this dip switch is set to ON, the weld-count monitor
function is selected. In this case, the INTERLOCK/WELD
No.SET is used to input the workpiece confirmation signal
[WELD No.SET], and the INTERLOCK/WELD No.ERROR
is used to output the weld-count error signal [WELD
No.ERROR] (see 4) on page 5-7).

⑪DSW2-(3) Selects a schedule No.
OFF: Starts with external schedule No.
ON: Starts with schedule No. on panel
If this dip switch is set to OFF, a schedule No. is selected
and operation starts upon the reception of start signal
[START 1, 2, 4, and/or 8] from outside. If this dip switch is
set to ON, operation starts upon reception of a start-signal
No. selected using the panel. The schedule can be
changed by pressing the SCHEDULE [NUMBER] key.
External start signals are used only to start welding, and
the schedule cannot be selected.
⑫DSW2-(4) Selects start using 4-schedule start mode or 15-schedule start
mode upon receiving an external start signal.
OFF: 15-schedule start mode
ON: 4-schedule start mode
If this dip switch is set to OFF, 15 schedules made by
combining start signals [START 1, 2, 4, and/or 8] are
selected. If this dip switch is set to ON, the
lowest-numbered start signal among 1, 2, 4, and 8 that is
on 20 ms after the first start signal is turned on, is selected.
⑬DSW2-(5) Selects Data Out.
OFF: Does not output data
ON: Outputs data
The data-out function is optional. Set this switch to the OFF
position when the option is not provided.
⑭DSW2-(6) Selects the control speed in constant-current control.
OFF: Half-cycle
ON: 1 cycle
⑮DSW2-(7) Sets the correction value for the constant-current control, or sets it
so that it is variable.
OFF: Fixed constant-current correction value
ON: Variable constant-current correction value
This switch should normally be in the OFF position.
When the weld control is used with a single-phase welding
machine, the welding current rarely rises abnormally to
overshoot or an extremely slow rise occurs. In this case,
set this switch to the ON position, making the
constant-current correction-value variable. When
DSW2-(7) is set to ON, Modes Nos. 8 and 9 are selectable
on the panel. Set the correction value for the initial rise
(G1) in Mode No. 8 (a larger setting provides a larger
amount of correction). Set the correction value for the initial
rise (G2) in Mode No. 9 after the current exceeds the
current setting (a larger setting provides a larger amount of
correction). When there is a big difference between
currents on the plus side and the minus side (the currents
are not balanced), set DSW2-(6) to ON (1 cycle).
