The switch cabinet and rectifier are designed integrally, which not only completes the function of switch cabinet, but also has the rectifier control function of solid-state high-frequency welding machine, which is also called thyristor（SCR）welding machine
One set of solid state high frequency welding machine including switch rectifying cabinet,inverter output cabinet,central console, mechanical adjusting equipment and circulation soft water cooling system and air conditioner ,optical fiber.
The solid-state high frequency welding machine uses the German IXYS company IXFN38N100Q2 38A/1000V high-power MOSFET and DSEI 2×61-12B 60A/1200V fast recovery diode to form a series inverter circuit.
There is no need to add a step-up/step-down rectifier transformer at the input end of a solid-state high-frequency welding machine. Compared with an vacuum tube welding machine or a parallel solid-state high-frequency welding machine, it has a more obvious energy-saving effect (compared to an electronic tube welding machine, at the same level). Under welding conditions, power saving ≥30%).
