Battery Powered Spot Welder

[bobcat2000]

Good Evening,

I found one of these selling on Amazon and Ali Express.  It is a battery powered spot welder.
What is the chance that these things will burn down my house or get me killed?  If not, have you tried to use one of these?  Does it work ok?

Thanks!

One of our members designed and sells one that won't burn your house down. Search for kWeld.

Yes, I already checked kWeld before I found those two portable ones.  I think Ali Express is already selling a bunch of clone of the kWeld for $10 already.

These two I found are interesting.  They put a battery pack inside the unit.  You charge it with a USB-C charger.

I can't imagine they will be able to provide very good power delivery with such minimal battery. I use a full sized car battery for my spot welder.
