Hello guys… and a few girls… :) I finally have a spot welder; a powerful one. 
Today I will show you in great detail how I made this nice spot welder. It works great, I really like it. The spot welder kit I’m using is very good. 

A big THANK YOU to all my patrons, especially to: Max Rice, Jacek, techge, Anthony Ortenzi, John.
