BUILD A DIY SPOT WELDING MACHINE 

😊

Зачем ты это сюда написал?!

@@villishon8921I was learning to do the first microwave transformer spot welder when I wrote it. Now my project have done and it work really well.

Just retrofit a continuum transfunctioner if you have one kickin about.

How is your welder working?

i soldered batteries too, and no problems(i corrected myself)

Very bad idea to solder directly onto Lithium batteries! The heat can melt/damage the insulating separator foil inside the cell, as well as boiling the electrolyte and causing venting from over-pressure. It's OK to solder (quickly) onto welded tabs already on the battery. However, the casing of the battery is a huge heatsink so you need to dwell a long time to get enough heat for solder to melt. This causes the damage to the cell. Much better to spot weld on bare (new) cells because the duration is far shorter, so less heat gets inside the battery cell.

​@@makantahi3731- do you weld or solder? They are two completely different things, and the OP was talking about soldering.

@@johncoops6897 i soldered many 18650 lion batteries and no problem

Hello brother plz send the board buying link thank u

Son muy interesante y se aprende mucho

It indeed has electrodes. Check this effect you have: en.wikipedia.org/wiki/Dunning%E2%80%93Kruger_effect

Timer delay circuit

Thanks bhai

Relay will fail very fast, due to the huge inrush current of the transformer. You need to use 120V mains supply if you use a 120V primary. The 3 turns gives about 3 Volts output, safe enough to touch onto your tongue. Using 2 turns reduces the voltage to about 2V so you need more current and time to make the same weld penetration. It doesn't really matter how many turns, having fewer turns just means you can fit larger secondary cable inside there, however bigger cable costs more and is more difficult to insert into the secondary. Whether 2V or 3V it will still need adjustment for welding duration, so it really doesn't matter either way.

he didnt fkin explain anything. might as well have videotaped a blank screen

there will be some loss in the high temp silicone wire, but its not much, the cable thats in the transformer is doubled up and thicker so it should be fine. if they used the red and black cable inside the transformer then you would be correct

3 závity - nedokončené - (viz video) u lepšího MOT dají 2,6 Volt.

You can do anything that you like with your 110V transformer. Please do not throw it off a bridge towards a passing car, as that might cause damage or injury.

Lol, thank you@@johncoops6897

I use 95% power and 5ms pulse

Thanks for your kind reply, I'm using P1.1 but don't know how to set power level and time. Can you help please ?

@@georgepilch8396 I use the NY-D01 Controller.

5 Amps ??? You should be getting 100, 200 or even more. You need BIG cable for the secondary. Absolute minimum 8 AWG, but preferably 4 AWG.

Have a close look @ the timer and you see HW 521. Google it and you'll find.

Search the usual online markets. They are widely available, and there are only a small number of models I total. The ones with Blue LCD screen and 100A SCR are the best ones, as they offer dual-pulse with duration setting for both Pre (cleans the surfaces) and Main pulse.

All items used are in the description

@@delancelloyd7781Yes I see you show the items you have used in your video but you don’t mention what size the AWG cable you have used for the second primary is or the shorter AWG is or how thick the copper plate bar is.Also the size of the welding Rod you have used and the screw bolts you have used to secure too the copper plate.Thanks

@@laurencemaud8205 Watch this clip. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-LMT1sn1bKRY.htmlsi=QmwMQ4-Pf3ZlIfHI The guy does more tests. My clamp meter measures up to 600 A. I put like him, 6.5 mm wire. I have over 600A. I cleaned off the white coating and covered the cable with electrical tape. The cable sheath is approximately 3mm/section. And the tape with which I covered the cable, is probably 0.5 mm thick. (I gained space.) But because the "termination" is made of 3.5 mm copper wire, the current dropped to 590 A. I haven't uploaded the clip yet. (Nede to be edited.)

Very small, in low melting point metals, maybe 0.01 mm, but ok for this. Consider the melting point of the electrodes, too.

you do not use physic's at all, as this will not work due oms law.
