Are you talking about the transformer or the spot welder?

The spot welder cost 228 USD :((

I am looking for can spot welding 0.2 nickel strip,but it’s too expensive…

I am from Taiwan, so the shipping cost is calculated.

It looks really nice. Looks like a production piece not a DIY. Good work.

Can you show the tip where you touch the nickel? I am building one also and could need some inspiration!

I built something similiar and it worked fairly well for my 3 batteries so far https://www.aliexpress.com/store/product/NY-D04-40A-100A-Digital-Display-Spot-Welding-Machine-Controller-Time-Panel-Board/2980008_32909000366.html?spm=2114.search0104.3.247.769d4d32GYvPR8&ws_ab_test=searchweb0_0,searchweb201602_5_10152_10151_10065_10344_10130_10068_10547_10342_10343_10340_10548_10341_10696_10084_10083_10618_10139_10307_10059_100031_10103_10624_10623_10622_10621_10620,searchweb201603_13,ppcSwitch_2&algo_expid=483e5009-27ed-42aa-87b9-874da8b9a607-38&algo_pvid=483e5009-27ed-42aa-87b9-874da8b9a607&priceBeautifyAB=0

not the exact link but something like that should work.

heres the one i used https://www.aliexpress.com/item/smd-fuse-2A-2012/32807721916.html?spm=2114.10010108.1000013.3.426b3402R8DrM3&gps-id=pcDetailBottomMoreThisSeller&scm=1007.13339.99734.0&scm_id=1007.13339.99734.0&scm-url=1007.13339.99734.0&pvid=78bfe558-c7a1-47e0-987a-54be5724f9df

See what problems you have encountered. I am not home now.

18

Yes, I use this one. I don’t know the difference, so I choose the one that is cheaper.

19

bro $228 is NOT a bad price. This can dramatically save people money making their own battery packs!

20

Nice, I think I might build one, I already have made a car battery one but i dont like it much…

Have you got a parts list? I think I can order the main electronics from taobao to speed up shipping

The housing looks really nice, did you make it yourself?
