What is nugget? How does nugget form? [DCS05]
The nugget formation process of intermediate frequency welder can be summarized as placing the welding piece between two electrodes, increasing electrode pressure, and releasing strong welding current to the welding area by the resistance welding transformer, which creates a real physical contact point on the weldment contact surface.

How to set the current parameters of mid-frequency welder? [DCS06]
Welding current is an important parameter of mid-frequency welder, the penetration of nugget depends on welding current. Assuming the other values are constant, increasing the current without increasing the strength of the solder joint will increase the rate of welding. Assuming the other values are constant, increasing the current without increasing the strength of the solder joint will increase the rate of welding.

How does energy storage welder save energy and reduce cost? [CD04]
The energy storage welder adopts the transistor element to carry on the program control. The heavy AC contactor and ignition tube are replaced by SCR in charge-discharge switch. As a non-contact high current switch, SCR has the characteristics of small size, no noise, easy to use and so on. In particular, its pressure drop is only 1/10 of the ignition tube, so that electricity can be used effectively. The charging voltage is precisely controlled and continuously adjustable by electronic switches and monitored by voltmeters. The circuit is equipped with an overvoltage protection device to prevent the breakdown of the energy storage capacitor.
