welding 18650 cells with DN-5 spot welder

[Joost]

Sorry for the late reaction.

I connect the spot welder too a 230V 20A D circuit brake. The problem was that the 'normal' circuit brake can not handle the in men's current. Now it work good!

Hi
I use a DN-10 spot welding machine to built batteries.

With new Sanyo NCR18650GA(10A)
3500mAh cell, the setting is less than 1, 0.95.
a stronger adjustment damages the negative pole to the point of piercing the capsule.
0,95 is enough for this cell , 0.2mm pure nickel tape .

Guys, I am about to buy one of these spot Welders. I want to be able to weld .2mm nickel sheet. Which model should I go for and what mods should I do? Replace the tips tungsten copper tig tips?

 

[ridethelightning]

depends on your plans.
for nickel, perhaps the dn5 is better.

the dn10 is awesome for making copper packs, but requires some modifications. not difficult, but work none the less.
small simple 555 timer circut(i have a diagram) + solid state relay
and some pieces of tungsten tig electrode for aluminium welding set into the ends of the electrodes

the dn10 for 0.2mm nickel (without mod )for example would perhaps be on the overkill side i think, risk damaging cells.

Quoka,

Did you research JP Welder on Endless-Sphere?

 

[ridethelightning]

+1, jp welder is perhaps better if you can get one.

Yeh, I would buy one in a flash but he is unfortunately unwell and not selling them anymore. I have a ghetto 788 sunko but I need the flexibility of welding an irrigular pack for my q76r. The dn-5 looks comparable although much more expensive than a jp spot welder
