I ordered the cheap batterie terminal spot welder of Ebay for obvious reasons. Sadly it went up in flames on 1st. use. It looks like the 5 MOSFETs that are connected in parallel are not able to handle the passed through current even thought each MOSFET is rated with a 300 amps pass through current. 5x300A is 1500A in theory but if the MOSFETs are not switched at the exact same time the current runs through which ever are switched first and they literally burn away. I only wonder whether of motorcycle batterie with a max current of less then 300A might not result in a disaster like this.
Maybe I really only received a faulty unit and for the approximately 20 Bucks it definitively was worth a shot, but maybe it is just too good to be true.
