Heyyy Kasyan, Thanks for sharing. I always enjoy watching your videos because you always show the schematic and they are usually good.

I notice you use a hard drive magnet to hold the 18650 battery while spot welding. Nice!

frequency is dependent on the 47uH and the 1 uF capacitor. approx 22KHz.

Dude please do part 2, where you list all the parts needed so people who lack experience can find the parts and purchase them. Additionally show us how to build the device step by step. That will be appreciated by most of us. :)

your channel is unique 👍

This project is very good!

Not shown is the actuating switch for the power on off. A timer circuit, maybe 555, would not be difficult to incorporate to give more precise control to welding parameters. Like simple approach, bare bones, ripe for development. Also nice touch, using HD magnet to hold cells during operation. Thank you.

yes! i would like a part 2!

is this circuit carry shortcircuit load? you use same circuit in soldering gun

I have the China $200.00 USD welder and yours does a better job than mine. Great job

Give me the linkshop..bro?

Now that's a cool little device.

Great job, Kasyan. This is simple and looks to be working great - exactly what I'm looking for. I'm a little confused about the transformer, though - can you elaborate a little ? You could get a small adjustable timer kit to make sure you only 'fire' 1 second.....

Frank ter Beek A basic inverter circuit converts DC to AC and the transformer lowers the voltage while increasing the current.

when can we see inverter part 2

Hi the circuit looks like a "tank circuit". You can find the circuit already made on Ebay look for "induction heater" Also have you tried aluminum foil for the secondary winding? I will have to give it a try.

any 1 know if C3306 or tip121 transistors will work

very nice, thanks for sharing.

Can we have a part two - more details ? I need to make this myself for creating battry packs of 18650's....

Can we use ne555 as delay for this circuit?

You should change channel name to electro borat yes . :P

can i use irfz44n instead of irfp150

Can you make an inverter arc welder?

irfz44n can do just as good as the 150n, but costs 0.30$ instead of 1$ on average. the irf540n handles 30 instead of 44 amps while maintaining the 100v drain-source parameter also at 0,30$ instead of 1$ per unit. i wish you could do some switching regulator converting from 220 mains to 0-30 v 200 amps for chargers and arc welders

John Scarce depends which way ya go transformer cheapest from microwave or somat like a 24v drill Batt charger transformer ..rewind secondary​ coil with 2 or 3 turns but use enameled wire so u can add same length windings (increase current) ...it wud be expensive to use a switching power supply with 200amp output there's a arc controler in the welders to keep the arc constant this is a pulse one shot type ....have you had a look inside a arc welder it looks crazy lol

well at least high power power supply would satisfy me. i have microwave transformer and its useless on its own both for welding and power supply.

Yes, high frequency means small transformer will do the job.

Part 2 please, my friend.

Hello. I made a welder spot, according to your scheme. unfortunately, I cannot make a connection between the two plates. my inverter can heat this metal to red between the terminals when the inverter is turned on for a long time (3 seconds). do you have any advice?

Thank you for demonstrating the smallest DC spot welder. Unfortunately, you did not show the REAL power supply {1} with which the spot welder functioned, even though it was shown in the schematics. Schematics shows switching to 2X Gates of IRFP150 through 2X300R. the power is still {2} on to the circuit through L1. Need explanation to {1} and {2} Thanks.

Your link for the calculation of the frequency for LC tank is defunct.

@@vex9596 meybe they make it paralel, depends on the resistor value ..

Why can't you use 10x 4700 uF caps in parallel (for lower ESR) and connect it to a 12V power supply through a 1 Ohm 10 watt resistor (over 0.56 Coulombs), so as not to overload the power supply and the on/off switch, when charging the caps? Once the caps are charged, you are ready to touch the probes and the charge stored in the caps will rush in and do the spot welding?

That will also work. Many ways to skin a cat and he is showing his version which is smaller. In fact with 5 turns on the primary and 1uF cap in the resonant circuit it has 0.5CV^2 = 2.88E-04 Joules; and your version is 3.38J and is comparatively much larger but much less complex. In fact even with 1x4700uF capacitor it has over 1100 times the energy that is contained in his version. So then why even have the cap? You can use a 12V car battery directly without any capacitors. The energy in your version may even be too much and may blow a hole in the battery contact. But again it is something to consider.

The thing is connecting spot welder leads produces heat from high currents but It may seem impossible to some soldering stations to beciome a spot welder since few of them offer low currents.

IRFP: Rds = 0.055 Ohms; Vds = 100 V; Pulsed Drain current 160 Amps. IRFP15N60: Rds = 0.385 Ohms; Vds = 600V; Pulsed drain current = 60 Amps. So if instead of 12V input battery you use 48V battery and make the transformer primary turns 16+16 keeping the secondary the same copper strip it should work. But now you must use 12V Zener diodes from gate to source to protect the transistor gates.

I did not see you welding anything to the positive side of the 18650 batteries, is that because you cant weld on the positive side of the batteries? Because if you cant then this thing is useless for making 18650 battery packs!

Excuse me, the 5+5 wire that you mention is 0.5 mm?
