Problems solved by technology
[0003] The above existing technical solutions have the following defects: when the welding machine is working, the welding speed of the welding machine is different for different welding workpieces, and the sending speed of the welding wire is also different, and when the welding speed is different, the corresponding The wire feeding speed also has a certain limit value. Although the above welding machine can adjust the wire feeding speed through the manual switch to deal with different welding workpieces, it may not be able to know in time that the wire feeding speed is at the maximum value of the corresponding welding speed. Make the wire feeding speed too fast and cause the welding failure of the workpiece

Embodiment Construction
[0050] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0051] refer to figure 1 , is an intelligent control gas shielded welding machine with liquid crystal display disclosed in the present invention, including a digital control module 1, a wire feeding control module 2, a power module 17, a selection module 6, an output protection module 7, and an output judgment module 8.
[0052] The digital control module 1 is used to process the received data and control the work of the welding machine. The wire feeding control module 2 is coupled to the digital control module 1 and is used to control the sending of the welding wire from the welding machine; the digital control module 1 stores information corresponding to Low wire feed speed database 3 for low speed welding, medium wire feed speed database 4 for medium speed welding, high wire feed speed database 5 for high speed welding, low wire feed speed database 3, medi...

The invention relates to an intelligent control gas shielded welding machine with liquid crystal display. The machine comprises a digital control module, a wire feeding control module, a selection module, an output protection module and an output judgment module; a low wire feeding speed database corresponding to the low speed welding, a medium wire feeding speed database corresponding to the medium speed welding, a high wire feeding speed database corresponding to the high speed welding are stored in the digital control module; the maximum wire feeding speed values corresponding to the low speed welding, the medium speed welding and the high speed welding are preset in the output protection module; and the output judgment module is used for judging whether or not the welding wire feedingspeed of the wire feeding control module is smaller than the preset maximum wire feeding speed corresponding to the welding speed. According to the machine, the output judgment module is used for comparing the maximum values of the wire feeding speed corresponding to the welding stages in real time, when the speed of the wire feeding is larger than the preset maximum wire feeding speed of the welding stages in the welding process, the digital control module can stop welding work of the welding machine so as to reduce the situation of workpiece welding failure.
Description
technical field [0001] The invention relates to the technical field of electric welding machines, in particular to an intelligent control gas shielded welding machine with liquid crystal display. Background technique [0002] Existing welding machines, such as a Chinese invention patent with publication number CN101786194A, disclose a hand-controlled wire feeding TIG inverter welding machine, which consists of a welding machine, a welding torch, a wire feeding machine, a wire feeding control unit, and a wire feeding tube. component, and a manual switch set on the handle of the welding torch. There are two switch potentiometers on the manual switch, one of which is connected to the control unit of the welding machine for controlling arc ignition and arc extinguishing and Adjust the welding current; another switch potentiometer is connected with the control unit of the wire feeder to control the start and stop of the wire feed and adjust the wire feed speed. [0003] The abov...
