Remote-control device for carrier wave of electric welding machine

Abstract

The invention relates to an electric welding machine carrier wave remote control device with excellent anti-interference and anti-fading performance which comprises a main control panel and a welding cable of the electric welding machine and is characterized by being equipped with an electric welding machine carrier wave remote controller; the remote controller consists of a display unit, a key-press unit, a carrier wave send-receive drive unit which are connected with each other, a voltage regulation power unit and an CPU unit with a modem, and is used for setting up, sending and receiving and displaying the welding parameters; the two output connection lines of the carrier wave send-receive drive unit of the remote controller are connected with an electrode holder and a ground clamp of a welding cable of the electric welding machine; the carrier wave receiver arranged inside the electric welding machine consists of the connection of the carrier wave send-receive drive unit, the voltage regulation power unit, the CPU unit with modem and a D / A simulating signal output unit, which is used to receive the set welding parameters sent by the remote controller, and reflect the current welding parameters; the receiver is connected with the main control panel of the electric welding machine through communication interface or D / A simulating signal interface.

Description

technical field [0001] The invention relates to a welding remote control device for an electric welding machine, more specifically, a remote control device for realizing remote data or information transmission of the electric welding machine by using a welding cable of the electric welding machine to transmit a carrier signal. Background technique [0002] At present, the known remote controllers for electric welding machines are divided into wireless remote controllers and wired remote controllers. Wireless remote controllers are less practical because they need built-in batteries, and wireless signals are greatly disturbed in industrial environments; wired remote controllers are divided into digital remote controllers. The remote control for transmitting signals and the remote control for analog transmission signals must be connected with a multi-core remote control cable between this type of remote control and the welding machine. For long-distance welding construction, th...
