Spot welding is a welding method that joins metal surfaces using heat produced from electricity. Some describe it as quick and easy, while others view it as inefficient and inadequate if not used correctly. Machines for spot welding may cost a lot, too, but if you’re clever enough, it’s also possible to build your own.
In this project, the video creator ‘poroldchap’ shares how he built a spot welder using the old parts from a microwave oven.
***He, however, warns that this project is not for the inexperienced as getting it wrong is dangerous and could result to severe injuries.
