I don't think so, just an average guy kicking back and having fun

On the output it is best to have as little resistance as possible. I therefore tinned the output leads connection to the board and as the bus bar connections. In addition I soldered the copper cables into the copper electrodes which I hold in position before pushing the foot switch. I get much more flash and have never needed to move the power from the lowest setting to spot weld successfully. This was after advice from my electronics guru friend, who said that to get the amps up as much as possible the resistance must be as small as possible and demonstrated the maths to me using v=ir.

Love your vids, great info, great techniques!

I bet it does, but I would rather spend that time making videos than doing stuff over i don't understand :P

I would think that you would want to hold the electrodes as vertical as possible in order to reduce the area of tip contact. Since all the current passes through the tips, temperature is not just a function of energy delivered but energy per area of contact. Tilting the electrodes contacts the tapered sides of the points and increases the contact area, distributing the current over a larger area, and reducing the temperature. When you angle the electrodes you can see this in the shape of the dents created. It might be possible to estimate the area in contact by measuring the resistance between the tips prior to the weld, and adjusting the delivered energy appropriately, but this would be difficult to do with accuracy I would imagine. In summary, I think you would get better and more consistent welds if you hold the electrodes more vertically.
