sunkko 737g spot welder modification

Right out of the box this welder did weld, but only at the highest setting and only the thinner nickel plated strips that came with it. When I tried to weld 0.20mm solid nickel strips, I found that even on the highest setting the welder was unable to do its job. Sorry, I should have shown video of the welds before the modification but this video was too long already.

After modding the welder I was easily able to weld 0.20mm solid nickel even on the positive side which is harder to weld to to begin with. I also noticed that I had to turn down the current when welding the thinner nickel strips and that's the way it should work.
