There is a new Version of the Spot Welder available. Read more to find out what has changed in V3.2
Please note: All orders since January 15, 2018 already shipped with the new V3.2 Prebuilt Kit or PCB Set.
In V3.2 there have been some small changes to the Arduino and the Mosfet board. It is now possible for the user to assemble the prebuilt kits completely without soldering. This was achieved by changing the pad distance of the 12V and GND input pads on the Arduino board to 3.5mm. The prebuilt kits from now on will come with a screw terminal installed to these pads. If you built the Spot Welder on your own you have the choice to use a srew terminal or directly solder wires to the pads.
- the Arduino Board was updated so it is now possible to mount a 3.5mm screw terminal to the input pads.
- the voltage measurement now connects directly to the 12V input pad instead of behind the schottky diode. This guarantuees a more precise voltage measurement.
- the 8 small SMAJ13A-13-F TVS diodes have been removed from the mosfet board. There is now one of these diodes on the Arduino board that protects all mosfet gates at once.
