take some test welds

This is what I was playing with before. Was expecting to blast holes in the cell at them settings

@Darkie02

Iv been trying out settings on cheep eBay battery and 0.3mm Nickle strip increasing then pulling it off with pliers. It started to get stronger about the 120j and I can feel the heat building guessing about 40 deg if I toutch it straight after welding heat gone after a second. I’m worried I’m using to much energy. What people’s opinions? More or less?

130j I started to rip a hole in the Nickle when pulling it off on 1 contact. 100j seemed to start to leave a little Nickle behind.

@Darkie02

so it seems I need different settings from pos and neg terminals. My tests found that using a new batty and Nickle strip I was pulling it off easily with pliers.

I think this is a little to much energy but is the strongest join so fare by a long way.
