Gas shielded automatic welding control device

Abstract

The invention relates to a gas protection automatic welding control device. The gas protection automatic welding control device comprises a controller, a remote-control box and signal transmission cables. The controller is composed of a waveform control module, a numerical value display module and a switching power supply. The remote-control box is used for controlling arc starting, walking, arc quenching and stopping of a welding gun. The remote-control box is connected with a welding machine or a welding tractor through one signal transmission cable, the controller is connected with the welding machine or the welding tractor through one signal transmission cable, and the remote-control box and the controller are relatively independent. The gas protection automatic welding control device is small in size, simple in structure, flexible and convenient to operate, low in manufacturing cost, capable of achieving switching of a DC welding function and a pulsation welding function by being matched with a common economical and durable DC gas protection welding machine, and particularly suitable for welding application and popularization under the severe environment condition such as a workshop environment and an outdoor environment.

Description

technical field [0001] This patent relates to a welding device, in particular to a gas shielded automatic welding control device. Background technique [0002] With the penetration of automation technology into all walks of life, automatic welding gradually replaces the important position of semi-automatic welding in factories. Since the flexibility of automatic welding is relatively poor compared with semi-automatic welding, the performance and control requirements of welding equipment are very high, and welding machines with excellent performance, precise control, multi-function, and full digitalization are expensive, difficult to maintain, and require professional operation. It is not suitable for most factory workshops, especially for promotion and use in complex welding environments such as on-site welding and field installation. [0003] Adding an external controller on the basis of ordinary welding machines can effectively solve the technical problems of equipment co...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the current high-cost gas-shielded automatic welding machine which is difficult to popularize in enterprise workshops and field installation sites, and the shortcomings of AC and DC square wave controllers for submerged arc welding power sources, an external connection with low cost, simple control circuit and convenient operation is proposed. Control device of ordinary gas shielded welding machine
