Brief principle

The schematic diagram of TIG series welding machine is shown in Figure 2:
Rectification
This welding machine adopts IGBT high-frequency inverter technology,
power frequency 220V power input, directly rectified and sent to the inverter
composed of IGBT and other devices to become high-frequency AC, and the
high-frequency
high-frequency transformer After stepping down, the high-frequency rectifier
rectifies and filters and outputs a DC current suitable for welding. Through
this process, the dynamic response of the welding machine is improved, the
volume and weight of the transformer and reactor are reduced, and the
efficiency of the whole machine is improved.
The design of the control circuit enables the welding machine to always
