Abstract

An automatic control system commutator for an air protection argon tungsten-arc welding in the technical field of welding includes a welding power interface circuit, a manual control circuit, an automatic control circuit, a computer interface circuit, a first shift switch, a second shift switch and a third shift switch used for connecting a welding power and a computer during the welding process of the air protection argon tungsten-arc welding and realizing the automatic control and manual control of the computer to the welding process. The invention adjusts a welding current and the size of a wire feeding speed in real time through the computer during the welding process and gets the welding process state information like arc starting, arc failure and pulse coming, etc., in the air protection argon tungsten-arc welding process in real time and realizes the effectively automatic control on the welding process.

Description

Technical field [0001] The invention relates to a device in the technical field of welding, in particular to a gas shielded argon tungsten arc welding (GTAW) automatic control system adapter. Background technique [0002] At present, most of the welding machines used in industrial production adopt manual control. With the development of welding technology, it is urgent to use computers and other intelligent devices to automatically control the welding process. Usually, a computer is used to automatically control the welding process. It is necessary to use a data acquisition card or use the computer's I / O port to connect to the welding power source and then program to control and detect the welding process. Due to the high frequency and high voltage interference in the welding process, if the computer is directly connected to the welding power source, it will cause great damage to the computer. Therefore, it is necessary to design a switching circuit to connect the computer and th...
