[@azym2091]

Couldn't be more simpler and clearer than this!

[@Jenevie_Delloson_]

You can do it simple without using transpormer and briagde rectafire, some diy like this is used 12v charger 1 or 2 capasitor,diode, and wire. Im also than doing it in a year ago take note to use diode if you will use 12v charger or other 12v supply to protect it from fly back of capasitor

Can we use 5000uf ,50 volt capacitor in this, And transforer 12-0-12 ?

Yes, you can use i used 9-0-9 v transformer because capacitors spot welders perform better with lower voltage but higher capacitance, so that it will store higher current with low voltage.

Can i use 25v 6800uf capacitor instead of 35v 6800uf? Please reply i need know

Yes as far as the transformer output voltage doesn't exceed 25v

[@jaywin_82]

Is the power supply source 9v AC?

[@petrok8618]

1 this approach needs powerful thyristor for commutating capacitors in moment of welding to avoid sparkles and make welding of better quality. 2 you should pull off stripe by plyers until stripe will rip off from battery. If spots of welding will stay on battery can - then it's quality welding. Otherwise - no.

[@kezzkezzkezz]

What other Capacitors can be used, I can't get 6800uF in my country

[@CreativeTechos]

You can use higher uf capacitors, if available use 1 Farad capacitor with 2-5 volts. It will perform better, Also if you would like to make professional spot welder for daily use with strong welding check out this video kzbin.info/www/bejne/nXqphqhjYteJfJY

[@kezzkezzkezz]

@@CreativeTechos would the 1 Farad still fit the designed PCB you made? I received them from jlcpcb

[@CreativeTechos]

If you've got your PCB than same size capacitor must be used. 1 Farad will be bigger.

What is the purposes of that single diode?any way the bridge rectifier will convert ac to dc..

I think it is to protect the transformer, because when you making spot you are making short circuit in whole circuit.

buenas mi hermano como estas, me gusta tu proyecto pero tengo una pregunta perdona mi ignorancia ese diodo que colocaste de salida negativa de los filtros y lo colocaste a la salida negativa del cuadro de diodos que función hace porfa 👍👍

[@CreativeTechos]

The diode i used on mosfets with reverse polarity, is actually a Recovery diode, that protects the mosfets from burning by continue turning on, with diode it discharges the fets and switchs them back to off position, when there is no pwm signal from 555 ic to gate of mosfets.

Can i use 50V 68000uf?

[@sreekumarUSA]

How do I order for the PCBs. The description wasn’t clear. Would appreciate if the link is forwarded. Thanks.

[@meisievannancy]

So this transformer is 18Vac at 1A rectified with a full bridge which must exceed the 1A when shorted out on the 4x 6800uF 35V caps = 27200uF total and 24Vdc on the caps before discharge. You can then use a lower voltage but increase capacitance. Q = CV which means if you half the voltage you must double the capacitance. But I would use low ESR 105C capacitors. They discharge harder because the ESR (electronic series resistance) is lower. Also instead of the 1N5408 I would use a 100ohm 5W resistor so as to not burn out the transformer. The time to recharge would then be about half a second.
