Spot welder control module (SWM-103
(12864 double pulse type - English
interface)) instruction manual
The spot welder control module is developed for
DIY or simple battery welder. It is mainly used for
single battery or battery group nickel plated sheet
welding, such as 18650 lithium battery nickel plating
0.15 and 0.2mm steel sheet, 500W transformer can
be welded directly. It is intended to weld other battery
materials and different thickness, such as polymer
battery electrode without nickel plating, must be
combined with sufficient power transformer to weld.
This module includes main board and display board,
optional 40A and 100A bidirectional silicon control
rectifier (SCR), does not include welding transformers,
welding pen and other matching tools.
I. Scope of use:
1. DIY or simple battery welder development welding.
2. Welding of a single battery or battery pack.
II. Functional overview:
1. Can be set to save the last operation, the module
double pulse trigger, turn off any set of trigger time,
you can change double pulse to single pulse trigger.
The need for a single pulse can also select SWM-101
digital tube model.
2. The main board and the display operation panel are
separated, and the outer casing can be flexibly
assembled.
3. Multi-group data 12864 visual display, intuitive
operation, convenient, single encoder parameter
adjustment can make the operation simple and fast.
4. With grid voltage compensation, the output of
compensation can be automatically adjusted
according to the change of power supply, and the
electric voltage of about 1 second can be displayed
when triggered, so that the effective heat of welding is
consistent with the welding parameters, and the
welding spot is uniform.
5. With 0-9999 welding counting function, with 5
groups of sample storage parameters, can be stored
even the electricity power is off, the number of wleding
could be seen just by a glance.
6. Time input 0-99 cycle (1 cycle is 20ms, for example,
the adjustment value is 50, which is the welding time 1
second.), the stop time between 2 weldings is 0-99
cycles (1 cycle is 20ms, such as interval value 50, It is
the interval of 1 second.) adjustable. Welding strength
30%-99% is adjustable.
7. The module can isolate the strong and weak
electricity by optical coupling, and design a reliable
circuit for zero-crossing detection and voltage
detection to ensure the accurate phase shift of silicon
control rectifier (SCR), which can be compatible with
40A-100A bidirectional silicon control rectifier (SCR).
8. 9-12 V AC power input (using AC transformers,
other such as DC, can cause zero-crossing detection
failure, can not trigger.)
9. The power input and external trigger adopt
convenient and quick welding free terminal, the
external trigger can be diversified, such as normal
switch, foot switch, external signal source input, etc.,
the software has anti-lock state, triggering to the end
of welding, for one round. For example, the pedal
switch has been trampled all the time, can only trigger
one round.
III. Usage method:
1. Voltage calibration
]The module has the network voltage compensation
function, so the voltage calibration must be carried out
when the first machine is installed, and in the future,
as long as the module power transformer is not
replaced, there is no need to recalibrate. Of course,
when you feel that the display voltage is wrong and it
can be calibrated. The following are the mains
voltages that are not calibrated and displayed during
operation:
]Calibration operation: press and hold the encoder to
power the module to enter the calibration interface,
the first flicker can be adjusted by the encoder once,
after the third bit, the short press encoder can enter
the operation interface. For example, the measured
voltage is 220 V, the calibration interface can be set to
220.
The following is the trigger interface to display the
local electrical voltage:

]2. Display interface
T→Time C→Current INT→Interval EXT→Extract
Interval: idle time between two welds.
3. Numerical adjustment: long press encoder, enter
adjustment interface, when numerical corresponding
value double digital flicker,
Short press encoder, with a single digit flickering left or
right to adjust the value,
Short press the encoder to change the next digit.
When the double digit flashes, the left or right rotary
encoder changes the next parameter adjustment.
When the count value is greater than 0, rotate the
encoder to the counting position, short press the
encoder, left-hand or right-hand encoder to clear.
When "exit" flashes, press the encoder to exit the
adjustment interface. When exiting the interface, the
encoder is double-clicked within 1 second, the current
parameter content can be saved as the next call
parameter (template save parameter), and the save
position corresponds to the calling position.The save
position is 0-4, and when it exceeds the maximum
value, it is overwritten from 0.
4. Extracting saved parameters（EXT→Extract）：when
“▬ ▬” is displayed, it indicates that the current
parameter is changeable and can be adjusted freely.
The last adjustment is saved by default. When the
calling parameter value is 0-4, it means that the
current parameter comes from the template saving
parameter (double-click encoder within 1 second).
The current parameter can not be changed except the
calling state (EXT) can be changed and the count
value can be cleared to zero. Other parameters
cannot be changed.

IV. Precautions for use
1. This module DIY needs to have certain electrician
knowledge, if you are complete freshman, please refer
to the electrician's knowledge before you start. Pay
attention to the safe use of the high voltage part
during installation. When the usage frequency and
power are high, silicon control rectifier requires
external radiator to disspate heat.
2. The power of the module driving load depends on
the power of silicon control rectifier (SCR). BAT41
(40A) can carry a microwave oven transformer,
BAT100 (100A) can carry two microwave oven
transformers, and the recommended one for Loop
transformer is 100A.
3. Do not know the welding time and power of the
welded parts, it is recommended that the welding time
and power be adjusted from small to upper to avoid
damage to the welding pen.
V. Fault cause and troubleshooting
1. The electricity supply does not match the actual
electricity voltage: re-voltage calibration.
2. The solder joint is not secure or soldered: adjust
welding time and power until satisfactory results are
achieved.
