You always deliver, thank you 👍

[@davidparrot4669]

thank you so much

[@satyabratray7352]

What about components, do they come with pcb?

[@satyabratray7352]

Or we have to buy it separately

[@gautamkumar7]

Very nice video...Can I buy one pcb from you...If yes please reply I'll share my contact details...😊🙏

[@NAANsoft]

Placing the pushbutton at 4:25 is clever! Nice and professional solution, all in all.

[@CreativeTechos]

Thanks for watching my friend 🙂

[@putriamalia422]

if I want to change increase or decrease delay time, which part should I change, sir ?

[@dans381]

The quiet music in your video is much better than your other videos, I have to mute your other videos (you actually don't need any music). I really like this circuit too; you always seem to have interesting circuits.

[@CreativeTechos]

Thanks for your suggestion and for the appreciation 👍

[@4DRC_]

Just curious how did you get 10ms as the optimal time? Experimentally or is it an industry standard? A pot to make the timing a bit more adjustable would be nifty for if different metals require different times to achieve good fusion.

[@Electro_JK]

Will it run with 30 ampere battery?

[@CreativeTechos]

Yes minimum 30A battery, like car battery can also be used

[@hasnainkanani6711]

I made it, its perfect! 👍👏 How to decrease the ON time, or control it via potentiometer?

[@CreativeTechos]

I will upload v2 with this feature very soon

[@hasnainkanani6711]

Great, I will be waiting.

[@johnellis-f6z]

I find the spot weld could do with a longer duration what would I change to increase sot weld time to maybe 20 milli seconds, thanks

[@mehmetyuksel9465]

What can be used instead of mofset?

[@atheist_happie]

High power relays

[@bohicajohnson7203]

The board I have has C18. What is this capacitor? Thanks

[@HD5_Rider]

C18 which capacitor values?

[@putriamalia422]

Can i use IRF1404

[@CreativeTechos]

Yes you can use, also Don't forget to use input capacitor as shown in schematics

[@putriamalia422]

@@CreativeTechos ok thankyou shensei

[@utpalhalder2468]

Can i do this, totem pole amplify the ne555 ic output signal to connect more mosfet. I will be happy to answer and will make it.

[@CreativeTechos]

Actually it doesn't need to do "Totem pole" you can drive upto 10 mosfets without any problem, and Yes you can do Totem pole but Signal Resistor of 1k should be added on base of PNP & NPN Transistors.

[@utpalhalder2468]

@@CreativeTechos tnx sir

[@u0000]

Will this circuit run with a LiPo Battery 2200mAh and 35C discharge rate ?

[@turaaja3581]

hey. 1uF capasitor 85' (volt ????)

[@shnawerhumayon2975]

Sir can i use zn44 or 1404 mosfets

[@Inertia888]

Compare the datasheets

[@otonomosblog5972]

you can use any N mosfet, but put more mosfet is better.

[@sorahacks3104]

Can we use IRFZ44N

[@CreativeTechos]

Nope, use High power Logic gate mosfet

[@robjody1180]

Nice and useful work. Thanks for sharing

[@CreativeTechos]

Thank you! Cheers!

[@ziben123456789]

Can you share a list of the products used in the construction? I know they are on the video, I just noted the lack of information about, for example, the power of the resistor (how many watts)

[@bohicajohnson7203]

33 Ohm x6 1k Ohm x2 2.2k Ohm x1 10k Ohm x2 1N4007 FR207 BC547 5mm LED 1 uF x2 8 pin IC base 555 timer IC I'd guess low power resistors. EDIT I bought 0.5W resistors, they just fit on the circuit board.

[@mihaibalint8183]

do you know what 600A is?

[@CreativeTechos]

It os not continuous current, it is just pluse current for mili seconds, these each of a mosfets can provide 100A pluse current, check out datasheet.

[@kang2161]

Hi bro, how much voltage for 1uf elco?

[@CreativeTechos]

25v 1uf is sufficient

[@marcop4037]

@@CreativeTechos What about the Capacitor of 470uF shown on schematic (C18)? Same 25V?

[@johnellis-f6z]

Hi I have ordered the PCBs already where should I add c18 as there are no holes in PCBs board

[@CreativeTechos]

Please check Gerber file again on jlcpcb website, I've already given corrected file, where c18 is also added.

[@johnellis-f6z]

Ok thanks for your reply, I will see when they arrive

[@bohicajohnson7203]

What size is C18? This video does not have C18.@@CreativeTechos

Hola me encantó el circuito y tú trabajo felicitaciones me gustaría saber que programa usaste para el diseño del circuito

[@baxbanni2226]

It looks like KiCAD.

[@joseeliashernandez1791]

aparte de aplicar puntos de soldadura, se puede soldar metales ?

[@diymaster101]

This is very nice 👍🏾 I will make ❤️🙂

[@PIKAJULLA]

buenas hermano como estas. me gustó tu proyecto del soldador de puntos, lo hice igual que el tuyo el circuito de potencia, desde el momento que le conecto el negativo ya los masfet se cierran sin aver dado el pulso de corriente en el gate o pin 1. ya lo rebice bien pero el problema sigue. mientras este conectado a la alimentación ya tengo un voltaje en la salida sin haberle dado el pulso en el 1¿ que será?

What happened to c18

[@CreativeTechos]

Actually i had forgotten while designing PCB, so i corrected pcb & schematic file, it is important to use otherwise mosfets may ❤️‍🔥

[@bocilnuh4817]

Ini untuk resistor nya wattnya berapa

[@werner7156]

I tried several times to build a spot welder like this and no matter how I triggered it, one or more FETs always burned out at 8 V. Since I couldn't figure out what the actual problem was, I've now decided on a ready-made one Spot welding circuit board from China decided, I thought all the FET's I bought were fake
