DIY or BUY a Battery Spotwelder?!

I'm comparing Spotwelders you can buy of the shelf against the one I built. They work quite different and produce different results.
Which one is really worth it's money and what is not recommendable and the true cost of everything.

If you buy one get a Kweld. It produces the most consistent welds from all the smaller DIY welders.

That probe is big brain. Very wheelchair friendly

Hey leo! thanks for the vid. keep up the good work!

[rhiantaylor]

You mention an advantage of ac welders that current flows both ways through the weld - this requires a weld duration of 20ms or more, for one full cycle at 50 Hz but you recommend short duration welds and showed a 5ms duration...

Hello brother what to do then @(10:15)
I having the same problem
Please respond MCB gets tripping.

Kleine Frage. Die Periodendauer bei 50Hz beträgt 20ms. Ist denn noch ein vorteil beim AC schwißen. wo du wascheinlich auch nur 4ms stöße verwendest. Eigentilch sollte das ein Nachteil sein, da in dieser Zeit die spannung auch sehr minimal sein kann und dadurch nur eine geringe Leistung entwickelt wird?
Denn noch Danke das die du versucht hast alle arten zu erklären. Die waren mir noch nicht alle bekannt.

It only takes 5 to 10 minutes to cut winding out of a microwave transformer.
I done 4 about 1 years ago to make a arc welder.
I also made spot welder exactly the same with timing board.
That only took 5-minutes to cut winding out.
And is 1000w
If it's taking 3 hours definitely doing something wrong

I paid 380 for 52v 20Ah triangle battery. I'm wanting to get to 72 v and whatever I can do for distance. What do you think I should do? I never made a pack. I've got a soldier gun wire feed for starts.

I made myself a spotwelder powered with drone lipo batteries using mosfets.

mach mal einen test wie der Wiederstand zwischen nickel strips gegen gelötete kabel sind. Die Nickel strips kann man meist nicht so hoch belasten

Autobatterie 640CCA neuwertig 30, --- 500A starterrelais 6, - Timer 4, - Fußschalter 3, - Sicherung 3, -- Elektroden und Kabel 20, - . Also weit unter 100- . Und keine mosfets die mir um die Ohren fliegen.

Just for information, electrons flow from the plus to the minus pole. The definition was made before the physical knowledge was present.
