Shahriar introduced the other day a cheap battery driven spot welder.
Guess what?
Today a similar device showed up here.
I've bought it for ca. 67 Euro at Amazon. It is a
InLove-As-0532(Really, who comes up with these stupid names all the time?)
Picture from Amazon:
I did a little teardown and spot welded two Nickel stripes.
The construction is a bit different than the one from Shahriar.
The front panel with all the connectors and knobs.
Overview, front- and backside of the PCB. Lots of vias. The two battery backs are connected in parallel.
The OLED display, backside and in use. This thing is able to throw out 460A with ease!
The copper tips and the high current connectors.
I did a little test with two Nickel stripes and here is the result. Back- and frontside.
I've isolated the area between the display and the screws of the battery packs with Kapton tape, because the display is flapping in the breeze and it could shorten the battery packs. Not a good thing imo. It is recommended to check first the construction of such a spot welder before the first use. Shariahr mentioned this as well in his video.
Thank you for watching.
