However, since the wire feeding drive circuit is connected to the main (power) circuit, when the main (power) circuit is working, if the welding wire touches the workpiece, welding will be carried out at this time, and arc and spatter will be generated while welding. If the operator does not Caution, it may cause damage to the

Embodiment Construction
[0040] The present invention will be further described with reference to the accompanying drawings.
[0041] like figure 1 As shown, a wire feeding automatic stop system includes a power circuit 1 , a wire feeding control circuit 2 , a welding wire detection module 3 and a control module 4 . The power circuit 1 is the original circuit of the welding machine. When the welding wire contacts the workpiece, the power circuit 1 is short-circuited to melt the welding wire, thereby welding the workpiece. The wire feeding control circuit 2 is electrically connected to the power loop 1, the wire feeding control circuit 2 includes a transmission circuit 21 and a motor 22, the transmission circuit 21 is electrically connected to the power loop 1 through a coil coupled with the main transformer of the gas shielded welding equipment, or through The power circuit 1 is directly connected to the power circuit 1, and the motor 22 is electrically connected to the transmission circuit 21. The p...

The invention relates to the field of wire feeding control of welding equipment, and discloses a wire feeding automatic stopping system and a method thereof. The wire feeding automatic stopping systemcomprises a power loop, a wire feeding control circuit, a welding wire detection module, and a control module, wherein the power loop is used for outputting electric energy; the wire feeding controlcircuit is used for receiving the electric energy output by the power loop and driving welding wires to move; the welding wire detection module is used for detecting whether the welding wires are in contact with a workpiece and outputting a detection signal; and the control module is used for receiving a wire feeding signal, limiting the output power of the power loop, receiving the detection signal and stopping the working of the wire feeding control circuit and the power loop. The wire feeding automatic stopping system has the advantages and effects that by arranging the wire feeding controlcircuit, the control module and the welding wire detection module, the output power of the power loop is limited by the control module, and the working of the power loop and the wire feeding controlcircuit can be timely stopped, so that the welding operation between the welding wires and the workpiece is avoided, electric arc and splash are not easily generated, and operators are not easily injured.
Description
technical field [0001] The invention relates to a wire feeding control of welding equipment, more specifically, it relates to a wire feeding automatic stop system and its method. Background technique [0002] When the gas shielded welding equipment is working, the welding wire is transported through the wire feeding system. [0003] At present, the wire feeding driving circuit generally provides driving power to the motor through the main (power) circuit, so that the motor drives the welding wire to move. However, since the wire feeding drive circuit is connected to the main (power) circuit, when the main (power) circuit is working, if the welding wire touches the workpiece, welding will be carried out at this time, and arc and spatter will be generated while welding. If the operator does not Be careful, it may cause damage. Contents of the invention [0004] Aiming at the deficiencies in the prior art, the present invention provides a method for automatically stopping w...
