DIY Spot Welder - Arduino
DIY Spot Welder - Arduino
I needed a Spot welder for battery packs.
Most parts were found in my junkbox and this is what I came up with.
It´s based om a 1kW transformer from an old Micro wave owen and is controlled by Arduino Nano.
I plug in a foot pedal in the outlet to the left and set the welding time on the display.
I get a double welding pulse. The first for warming up and a second for the weld itself.
Nano can be reprogrammed direct from the front panel if necessary.
I´m no welding expert but it seems to functioning.
