Multisection switch apparatus of electric welder

Abstract

The invention discloses a multi-section switching device for an electric welding machine, which comprises a multi-section switch of the electric welding machine and a driving motor. The driving motor is connected with a rotary adjusting shaft of the multi-section switch of the electric welding machine through an output device and connected with a control circuit, the multi-section switch of the electric welding machine is connected with a real-time section detecting device, and an output end of the real-time section detecting device is connected to a section indicating device through a detection signal processing module. Because the multi-section switching device is provided with the real-time section detecting device, the multi-section switching device can accurately detect and indicate the section position of the multi-section switch during use of the electric welding machine, a user can accurately operate the electric welding machine and the use is more safe and reliable.

Description

technical field [0001] The invention relates to a structure of an electric welding machine, in particular to a multi-section switch device of the electric welding machine. Background technique [0002] At present, the current adjustment of the electric welding machine is usually adjusted by manually turning the manual adjustment switch on the panel of the electric welding machine. Although these electric welding machine mechanisms are simple, they have the disadvantages of inconvenient use and unreliability. The operator is often far away from the main machine of the welding machine when welding remotely, so he needs to walk back and forth or cooperate with other people to operate, which is inconvenient to use. Moreover, if the welding torch is still working when the current is adjusted by others, the contact point of the switch will be damaged, and the use is unreliable. [0003] In order to overcome the above-mentioned problems, the applicant disclosed a multi-stage switc...

Problems solved by technology

However, at present, the segment position indication of the electric welding machine with the above-mentioned structure relies on the single-chip microcomputer on the host computer to store it and display it to the operator through the indicating device. The status of the segment will cause the operator to use the error, which will bring economic losses and safety hazards to the production. Therefore, how to improve the above structure is an important issue.
