This spot welder contains a very large capacitor that is charged to a precise voltage then discharges through the material to produce a controlled cut. There are 5 key segments that make up the design ...

[Radu Motisan] wrote in to share a cool project he has been working on lately, a pulsed microspot welder/cutter. The device is capable of spot welding thin metals such as foils and battery tabs by ...

There are many applications which require pulse power. The needed burst of energy is derived by rapidly discharging a previously charged capacitor. As the energy stored in a capacitor is equal to ...

[Robert] needed to weld metal tabs on a few batteries. In a proper manufacturing situation, this is usually done with outrageously expensive welders. Not wanting to spend thousands of dollars to ...

Many power supplies use hold-up capacitors to keep enough energy at the full-wave or bridge rectifier output to supply a load when the rectified voltage drops and rises again at the next half-cycle of ...
