Principle of mos energy storage spot welding machine

How does a capacitive spot welding machine work?

A capacitive spot-welding machine, also known as a capacitive energy storage spot welding machine, functions by passing alternating current through a rectifier to convert it to DC and charging the capacitor. The electricity is then released as a pulse through the contact points of the workpiece to weld the metal.

How does a spot-welding machine function?

A spot-welding machine is a simple structure consisting of a high-power transformer that converts a higher voltage electricity source, such as 220V AC, into a low-voltage, high-current power supply. This power supply creates the heat needed to melt the weld joint by passing a high current through the workpiece and utilizing the resistance of the material.

What is spot welding?

Spot welding is a process mostly used for connecting thin plates, such as aircraft skins, aero-engine smokestacks, and car cab shells, among others. The structure of the spot-welding machine is simple: it is a high-power transformer that converts a higher voltage electricity source, such as 220V AC, into a low-voltage, high-current power supply.

What are the advantages of resistance spot welding?

Resistance spot welding in spot welding and spot-welding machines has several advantages. It forms a thermal fusion joint as the metal cools. This process has the characteristics of low energy consumption, low cost, high quality, high efficiency, easy automation, and convenient use. No consumables, such as welding rods, wires, or fluxes, are required.

How to perform spot welding on a machine?

To perform spot welding on a machine, first turn on the cooling water (if the welding machine has one) and then turn on the power. Once the power is on, the power indicator light should be on. Place the sheets to be welded between the two electrodes and perform the spot weld.

How to adjust the pressure on the welding machine?

To adjust the pressure on a Spot Welding Machine, you can turn the spring pressure nut on the electrodes to obtain the preferred degree of compression. If the machine has a cooling system, first turn on the cooling water and then turn on the power to prepare for welding. After the power is turned on, the power indicator light should be on.
