Embodiment Construction

[0009] The present invention is achieved through the following technical solutions:

[0010] A method for arc welding power supply to realize arc wire feeding. The method is to introduce arc voltage as the power supply of the wire feeding device during the welding process, and adopt different methods to drive the wire feeding motor according to the different characteristics of the arc welding power source. The automatic wire feeding system for MIMA welding works stably.

[0011] The present invention also provides a system for realizing the above method. Such as figure 1 As shown, the positive pole of the arc welding power supply (1) is connected to the arc wire feeding controller (2) through the positive pole welding cable (5), and the negative pole of the arc welding power supply (1) is connected to the welding workpiece (7) through the negative pole welding cable (6). ), one end of the controller power supply circuit (4) is connected to the workpiece (7) and the other end...

Abstract

The invention discloses a method used for an arc welding power to realize electric arc wire feed. The method dispenses with a control cable or a carrier cable between the arc welding power and a far wire feeder, wherein a wire feeder control system is directly connected with the arc welding power by the welding cable, the energy of an electric arc is directly utilized to drive a wire feed motor, and the programme control of an automatic welding process can be realized. The wire feed method dispenses with the control cable or the carrier cable. By connecting the welding cable used for transporting electric arc energy with the far wire feed system, the programme control of the wire feed motor and the automatic welding process is realized, and the stable working of the welding system is guaranteed. As automatic wire feed consumable electrode electrical arc welding equipment dispenses with the control cable or the carrier cable connected between the electrical arc welding power and the wire feeder, the welding method can be much more convenient, and the service reliability and the stability of the welding equipment are improved. Besides, the invention also discloses a system for realizing the method.

Description

Technical field [0001] The invention relates to an industrial arc welding equipment used for welding, in particular to a method and system for arc welding power supply to realize arc wire feeding. Background technique [0002] At present, arc welding power sources such as gas shielded arc welding machines, submerged arc welding machines, and flux cored wire self-shielded welding machines all use remote control via control cables or carrier cables to realize remote control of wire feeding devices. This wire feeding device requires Use control cable or carrier control line to complete the connection with the arc welding power source. The length of the control line is several meters to hundreds of meters, which not only brings difficulties to the operation, but also because the control line is often smashed into an open circuit or The short-circuit state makes the remote wire feeding device unable to work normally, resulting in welding failure. This limits the application rang...
