Carbon Lifeform
I just completed mine based on a similar system by a guy in the UK. Works great. Handles .15mm zinc no problem.
I used this for the pen and switch ($22)
Amazon.com
This for a secondary switch that I prefer. ($7)
Amazon.com
This relay ($13)
Amazon.com
A small old 300a AGM battery from my garage and some battery cables. (Free)
Makes perfect, strong welds for under $45 and it's fun to use.
Let me know if you need a more detailed wiring diagram.
To get the right duration, I just practiced welding a zinc strip to a large washer. Just a momentary tap on the foot pedal is enough.
I make lots of Lifepo4 batteries in 12/24/48v formats for testing. It's perfect for that.
Its a 300amp 13v pulse. 4000W!
If your want a bigger weld, simply tap again on the same spot.
Its handy, I've been fixing other things around the house with it, tattoo anyone?
