    DIY Arduino Battery Spot Welder

    Die MOSFETs wurden einfach zu heiss beim Löten. Habe sie jetzt geschaubt und alles läuft wunderbar.

    New MOSFETs and drivers ordered, the expensive part of this build.Luckily i have a new second board, but this time i will screw the MOSFETs on instead of soldering. I also did not cut the Drain Pin of the MOSFETs, maybe this was also a fault.It is a lead acid battery for big generators. I think it is way to much for the MOSFETs. I'll try first with a motorcycle battery next time.

    I'm using a 137A battery, is that too much? The nickel strip i tried to weld exploded.

    Built one and this thing instantly welded without pressing foot switch?!?!?One of the mosfet drivers gets really hot. Its the upper right.Damn, now i need to order spare parts, not so easy this project like it seems to.

    Habe alle MOSFET's durch gemessen und ich denke es sind alle bis auf einen kaputt. Zerstört das dann auch die MOSFET Treiber?Kann das an der großen Batterie liegen, oder eher dass sie beim Lötvorgang zu heiss geworden sind?
