Hello /diy/ I recently wanted to start making battery packs but I need a tool to do the spot welds. What tool do you guys recommend I use to do this?

Would prefer not to use cheap chinese shit or extreme diy (see pic)

Wire up sufficient 9V batteries to make a DC resistence spot welder with some sharpened jumper cable clamps.

If you want to be cheeky add a sewing machine foot pedal as a safety interlock.

jesus christ on a stick can you people not search on ebay and amazon? there are all sorts of spot welders.

self contained units, and devices you attach to batteries that use mosfets and timers.

hell you can do what I did and get a timer board from ebay connect that to a solenoid and use a car battery.

it's called trying! do you actually try?
