The solid state high frequency all-in-one welder consists of 5 parts: SCR all-wave rectifier, IGBT high frequency inverter +PWM voltage regulator, high frequency transformer, FRED quick recovery diode module high frequency rectifier, E-bridge inverter output.

Advantages：
1，The solid-state high frequency all-in-one welder adopts the full-wave rectification IGBT inverter regulation mode, and does not need the phase shift angle adjustment of SCR.Therefore, it has the advantages of high power factor and good power saving effect also reducing the cross section area of inputting cable.

2，The energy-saving solid state high frequency welder has an integrated structure and a separate structure, which can be selected according to the field space. The comparison picture is as follows:
