For welding batterytabs, i thought it would be nice to have a spot welder.
Parts needed
- Microwave transformer (got this)
- Thick-ass copper wire (profzon or the0 is getting this probably)
- Delay timer ( ordered http://www.ebay.nl/itm/262966589796 )
- Momentary switch
- Some kinda auto-fuse box?
- Case
- Welding handle
Build log
Got some work done today. First hit the secondary coil out of the transformer with a chisel and hammer. Then made a simple welding handle and used the 4mm2 (~awg 11) wire with two loops. Measuring showed I was getting about 1.6V. Welding sorta seemed to work, but couldn't get anything welded, and wires got very hot. Really need something thicker I guess ...
