As I was doing a review on a Spot welder 12v just noticed that also has been called resistance welding. This spot welder is a DIY welder, portable and lightweight, easily can fuse the nickel plates from 0.01mm to 0.12mm only using at least a 30ah battery or could be any other source that can provide instantly over 30ah current. Usage of the DIY spot welding is comprehensive mostly on 18650,16650 and 32650 lithium batteries.
