This battery welder is suitable for welding lithium batteries like 18650/26650/32650 effortlessly, especially with common 0.1 mm to 0.15 mm nickel-plated sheets.
12v spot welder offers a range of five gears, progressively increasing spot welding strength from the 1st to the 5th gear.
The 5th gear provides the highest strength and easily handles welding the typical 0.15 mm nickel-plated sheets.
So let's get into it.
Watch this video to understand this article more clearly.
So for it to work we need to connect it to a power supply for example how we did, we used car battery the supply needs to be something like that.
So from our car we took our big car battery electric crocodiles to hold the wires: black wire (-) and the red wire (+)
Then we connected them to our spot welder, then from the other we connect the wires with the copper stick coming out of them to the front of the spot welder.
After some off camera welding to try it, it seemed pretty good.
Oh, and also when you are welding with it, in the pack there's those black cases, and you put them on the front wires before welding, so you won't be electrocuted.
Switches power (1-5) every 3s, buzzer signals. Green light flashes post-weld. Reliable 90-150A power needed for 0.1-0.15 mm nickel sheets. AliExpress machine (<20 Euro) excels in lithium battery work.
