There is a new Version 3.1 of the Spot Welder available. It has a little improvement on the mosfet board that makes it possible to use higher CCA car batteries -> more welding current. Read more to find out the details.
The case for the Arduino Spot Welder got a design update so it is now more modular to use.
The SMD TVS Diode used on the Spot Welder V3 seems to have problems when using very big car batteries (e.g. 800 CCA). So it is recommended to replace it with a stronger one. Read more to find out the details.
To upload the Arduino Code of the Spot Welder V3 to the Arduino Nano you need to do some preparation. Read more to find out what to do.
There is a completely new version of the Spot Welder available. Read more to find out the details
With the help of this very simple addon you can power the Spot Welder directly from the car battery instead of a 12V power supply.
There is a bug that the Auto_Pulse feature will not work correctly when using the Spot Welder with the Diode Set. Read more how to easily avoid it when building the Spot Welder yourself.
New Batch of V2.2 PCBs arrived. There is a little improvement in the V2.2 PCBs now.
There is a new version V2.2 of the prebuilt kits available. It got some amazing new features and pcb upgrades.
In the new V2.2 PCBs the “AutoPulse” feature is integrated, but you can also upgrade your “old” Spot Welder with the new feature pretty easy.
