No problem guys, you're on!

Have you by any chance sold any of these welders to Norway (or Sweden)?
Could you PM me or put me in contact with any of them?

Hello
Please put me down for one kit. thank you

 

[riba2233]

No problem, thank you!

Hey,

I'd love to get on the notify list as well. If you'd be so kind.

Thx.

 

[riba2233]

Sure, you're on!

Also, I'm getting really close to finishing testing new version, and ordering new batch of PCBs! After that, I'm ready to start shipping, everything else is ready.

Riba, can you share the differences/improvements between previous and new version?

 

[riba2233]

Hi,

well, since some people have been asking me for DIY version, I designed new board that can be assembled easily. That also brings up few more things, production time will be faster, you will be able to save money by buying DIY kit, and maintenance will be a lot easier. Also, if someone want's to mod, it will be easy.
I must say that the visual appearance will be worse, but that's the realistic compromise. The old version was unjustifiably pesky to make, so we will remember it as being nice

I will show pictures soon, just need to take care of some details first.

sounds great riba!

 

[markz]

Yes the DIY route seems interesting, as long as its clear to assemble.
It would be good to get a general price too not only of the kit, but also what parts are needed so we can make a clear choice which way to go.

How does it looks beside I phone 6s now. Will I still look cool welding my packs?
P.S. Sorry, I could not hold it :lol:

Yeah, it will be pretty clear. I don't get the other question, general price of what exactly, price of parts used in my kit, or price of ither two thing you need for welding besides my welder kit, battery and AC supply?

LOL, good one :lol:

The price of your kit, along with the parts spec'd out for price. Like from mouser.com or something.

Hi riba,
add me to your waiting list, please!
Thanks,

Well, it's not as simple as that, there are many custom made parts, and greatest value is on PCB itself. So if you want I can give you the schematic and then you can try to figure out how much would it cost you to make.

Can I use my a123 batteries to hook up, lets say connect in 12V or 24V, and a peak of 350A - 1100A?

Whats the difference between hooking up in 12V or 24V?
Quicker re-tab time or something?

 

[riba2233]

Difference is that on 12 V it will work like it should, and on 24 V it will blow immediately 8) 3S is number you should use if you use lithium cells, 9-11 V. You shouldn't use more than that. Kepler is using 2S on lifepo4 and it's working fine

Also, you need at least 1000 A for proper welding, so keep that in mind. Sometimes it's really more economic to use small starter battery instead of lithium cells.

Hello could you kindly add me to the notify list for the ready made spot welding units?

 

[riba2233]

Sure, no problem

Even my poor SLA that is less than ideal fro starting has held up great as my welder! It sits at 12.5-12.9V and produces great welds.

 

[markz]

1kA peak, or cont?
My a123's are rated for 70Apeak each, so if I go 3S to get ~12V then whatever in parallel for the current requirements.
