Disassembly of capacitor energy storage spot welding machine

How to spot weld a capacitor?

Most spot welders use two points near each other or on each side of the workpiece. The current from the capacitor is probably just absorbed by the relatively large piece of metal. The second video below from [American Tech] shows a 500F capacitor doing spot welding with little more than two wires and it seems to work.

What is an adjustable spot welding apparatus?

An adjustable spot welding apparatus , developed by a team of authors, belongs to the type of semiautomatic devices and is implemented in a capacitor method without using a transformer . The discharge for the welding process gives a block of ten electrolytic capacitors with a voltage of 35 V and a capacity of 10,000 mF.

What are the advantages of spot welding apparatus?

Main advantages the spot welding apparatus: high performance; minimum heat affected zone due to high energy density and short pulse; connection strength; simplicity of technology that does not require highly qualified personnel; uniformity of the mains load at high welding currents. Let's consider the operation of the welding device in more detail.

Why should you choose an adjustable spot welder?

The cheapness of the development. According to the results of the calculations, an adjustable spot welder costs an average of 29% cheaper compared to analogues . Ergonomics and ease of use . The device is quite easy to disassemble, and bend the corrugated body of the electrodes in the required direction to perform difficult-to- access work;

How fast does a capacitor release energy?

of the capacitors in this device, and hence the release of the stored energy, occurs almost instantaneously in the interval of 1-3 ms. This minimizes the heat-affected zone in the welded joint. In addition, the simplicity of dosing energy and upsetting force results in a consistently high weld quality.
