Method and device for realizing remote adjustment of inverter welding machine current based on welding time

Abstract

The invention provides a method and a device for realizing remote regulation of currents of an inverter welding machine based on welding time. For the particularity of manual electric arc welding occasions, regulation of the currents of the welding machine is a time-consuming, troublesome and frustrating thing for an operator. According to the method and the device for realizing the remote regulation of the currents of the inverter welding machine based on the welding time, the detected welding time is adopted as remote control commands of encoding, a remote controller is not needed any more so that the remote control and adjustment of the currents can be realized without operating any accessories, and therefore the electric welding operator can apply a remote control system simply and efficiently; receiving modules for processing the remote control commands comprise a time detecting module, a time filtering module, an encoding and decoding module and a special driver driving a digital potentiometer or an electric potentiometer to operate so as to realize stepless regulation of the currents of the welding machine; and the regulation effect of the currents can be observed by the operator and can be subjectively determined in real time. The method and the device for realizing the remote regulation of the currents of the inverter welding machine based on the welding time are suitable for the inverter welding machine for overlapping the form of wireless remote control and regulation of the currents under the condition of reserving the function of manually regulating the currents and meanwhile are suitable for the newly-designed welding machine to be integrated on a PCB.

Description

Technical field [0001] The invention relates to the technical field of electric welding machines, in particular to a method and a device for realizing remote adjustment of the current of an inverter electric welding machine based on welding time. Background technique [0002] Due to the particularity of the manual arc welding workplace, adjusting the current of the electric welding machine is a very time-consuming, troublesome and helpless thing for all electric welding operators. This is because the form of the adjustment mechanism of the output current of the electric welding machine is indeed in this field. This has caused many inconveniences to welding workers. For example, the silicon steel sheet welding machine adopts the adjusting reactance to adjust the current! [0003] Although in the late 1990s, advanced inverter welding machines have almost replaced the traditional silicon steel sheet iron core welding machines and entered thousands of households, although it has been s...
