Global function pulse argon arc welding machine

The utility model discloses a global function pulse argon arc welding machine, including a rectifier module, provide the current input of the pulse argon arc welding machine on the rectifier module, the input of a rectifier module's output connection inversion modular, the 2nd rectifier module's of output connection of inversion modular input, the input of the 2nd rectifier module's output connection main control board, the output of main control board on the one hand, connection drive module's input, its on the other hand connection operation module, drive module's output connection inversion modular, set up master control circuit on the main control board, the last drive circuit that sets up of drive module. This kind of global function pulse argon arc welding machine after long -time work the can also retentivity can the stability, it is high to have improved the complete machine operational reliability, adopts drive module simultaneously, appears overflowing with overheated in having prevented the working process again.
