Detailed explanation of the working principle of capacitor energy storage welding machine

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.

What is the operating mode of a welding current pulse?

The duration of the operating mode (discharge) is set by the potentiometer R12 and it is 0.1; 0.2; 0.5; 1.0; 2; 5 and 10.0 milliseconds (ms). Welding current pulses, during which heating and welding of products are carried out, can be single and combined.

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.
