New Spotwelder - Most powerful yet?

I have since tested the newer version. See my new video

I bought a new spot welder from Ali Express. The interface is bizarre, but the board is beefy and the spot welder is more than powerful enough for any spot welding job! The way it works is it does 3 pulses and the 3 segment settings control the three pulses.

They dont seem to be selling this spot welder much any more although the replacement spot welder does seem similar also with 12 mosfets.

Here is the new design, which will be testing
