Digital communication inverter type gas-shielded welder

Abstract

The invention discloses a digital communication inverter type gas-shielded welder, comprising an arc welding power module (1) and a wire feeder (2), wherein, the arc welding power module (1) comprises a data receiving module (7) and an arc welding power (8); the wire feeder (2) is internally provided with a data transmission module (6); the arc welding power (8) is connected with the data transmission module (6) respectively through a data line (3) and a power line (4) after being in serial connection with the data receiving module (7); a welding cable positive terminal (5) is connected with the arc welding power (8) and the data transmission module (6) and is used as the common earth wire of the arc welding power (8) and the data transmission module (6); and the welding cable negative terminal (9) is connected with the arc welding power (8). The digital communication inverter type gas-shielded welder not only has strong capacity of resisting disturbance, and high reliability and stability, but also has saved materials, lowered cost and convenient maintenance.

Description

technical field [0001] The invention relates to a welding equipment for welding metal, in particular to a digital communication inverter type gas shielded welding machine. Background technique [0002] At present, the mainstream inverter type melting gas shielded welding machine mainly includes two parts: arc welding power supply and wire feeder. In the prior art, six control wires are usually used to connect the arc welding power source and the wire feeder to realize the information exchange between the two parts. Generally, sliding rheostat knobs, rocker switches, and jog buttons are installed on the wire feeder, and the welding voltage parameters, welding current parameters, jog wire feeding control signals, and welding torch judgment signals are transmitted through six control lines by adjusting the knobs, switches, and buttons. Provide the arc welding power supply to complete the setting of welding parameters and the input of welding machine control signals. The arc w...

Problems solved by technology

[0004] Technical problem: the purpose of the present invention is to address the deficiencies of the prior art, in order to solve the problem of poor signal transmission caused by interference and obstacles in the welding process due to the difficulty of moving and easy damage of the six control lines in the harsh electromagnetic environment. The technical problem of parameter display on the arc welding power source is invisible, and at the same time, in order to save costs, it provides a device that is easy to move, smoothly transmits control signals, easy to maintain, and displays the adjusted welding parameters on the wire feeder during long-distance welding.
