Circuit for controlling and identifying a plasma torch

Abstract

A circuit is described for controlling and identifying a plasma torch, the circuit comprising an electronic circuit board (100) provided with a microcontroller and arranged on the cutting plasma torch (200), controlling and identifying the plasma torch (10) to the central circuit board (30) of the equipment (300), via two wires (10) which form the "network" and ensure communication between the circuit (100) and the power supply of the equipment (300), making it possible to monitor and control all the actions of the equipment, dispensing with a multiplicity of wires, solving the problem of constant stops of the equipment caused by wire ruptures and making it easier to read the power of the plasma torch (200).

Description

technical field [0001] The invention relates to a plasma torch control and identification circuit. More specifically, an electronic circuit is used to monitor and control all activities of the equipment, eliminating the need for the use of multiple lines, solving the problem of equipment stopping due to damage to the lines, and eliminating the power of the plasma torch Difficult to read. Background technique [0002] At present, the plasma arc in the existing cutting system includes a power supply, an arc starting circuit and a torch. These parts of the above system are used to provide power, ionization capability and process control are particularly important in order to achieve high quality and high output efficiency in cutting of different materials, [0003] In the existing plasma torch cutting technology, a large number of transmission lines are used, and the arc maintenance circuit of the torch is started by pulling the trigger through two lines, and the driving is m...

AI Technical Summary

Problems solved by technology

[0006] Therefore, the lines that facilitate the activation of the maintenance arc in the plasma torch, the safety of the nozzle system and the identification of the torch power, are all opened and managed by equipment that is generally 10 meters away from the plasma torch, often causing the wires of the plasma torch to break, and Make data reading and management more difficult

[0007] This type of equipment, in addition to having multiple control wires, the maximum conduction current is limited to 80A, which also limits its range of use, and also causes the equipment to stop operating due to overloading and damage to the wires
