Description

technical field

[0001] The invention relates to an inverter square wave AC argon arc welding machine, which is mainly used for high-quality welding of aluminum materials. Background technique

[0002] The application of inverter technology in arc welding power supply has been very common. Today's mainstream square wave AC argon arc welding machines mostly use inverter mode (primary inverter). like figure 1 As shown, according to the classification of electrical functions, the inverter square wave AC argon arc welding machine can be divided into two systems, a power system 100 and a control system 200 . The inverter square wave AC argon arc welding machine is under the effective monitoring and orderly control of the control system so that the power system 100 converts the grid high-voltage positive-rotating AC (fixed frequency) into a low-voltage square-wave AC (variable frequency) and finally passes The welding circuit completes the conversion of electrical energy to therm...
