example 1

[0022] Example 1 Welding equipment with semi-automatic darkening welding helmet suitable for argon arc welding machine

[0023] The argon arc welding machine has a manual micro switch on the welding torch, which directly controls the work of the welding machine. Therefore, the dimming controller of the semi-automatic dimming welding mask is relatively simple, as long as it can provide a delay and obtain a small DC drive from the welding machine. The optical shutter can work normally. Dimming controller can adopt analog circuit, or digital circuit.

[0024] If digital circuits are used to design the dimming controller circuit board, the advantage is that the aforementioned delay time and the voltage output to the dimming shutter are easy to adjust. The disadvantage is that the circuit board design will be slightly complicated, and the current consumed by electronic components such as MCU is higher than that of analog The circuit needs to be large, and the cycle of software and...

[0026] Example 2 Welding equipment suitable for ordinary electric welding with semi-automatic darkening welding helmet

[0027] The controlled electric welding machine used in this technology must be able to control the work of the controlled electric welding machine, while ordinary electric welding machines do not have manual micro switches like argon arc welding machines, and different types and manufacturers of products have different working circuits , It is usually necessary to design the control circuit according to the specific situation, so that the welding machine becomes the controlled electric welding machine required by this technology. Generally speaking, compared with the semi-automatic dimming welding mask system of the argon arc welding machine in the previous example 1, the power conversion part and the start-stop control part of the electric welding machine should be added. Because this part of the circuit design does not belong to the technical innovation po...

Abstract

Provided is welding equipment with a semi-automatic auto-darkening welding helmet. The equipment comprises a manual control switch, an auto-darkening controller, an auto-darkening optical gate, a welding helmet shell, a controlled electric welding machine, a welding gun and cables. The manual control switch is fixed to the welding gun, the auto-darkening optical gate is fixed inside the welding helmet shell, the welding gun is connected with the controlled electric welding machine through the cables, and the auto-darkening controller is connected with the manual control switch, the auto-darkening optical gate and the controlled electric welding machine through the cables. The manual control switch is pressed down during welding, the controlled electric welding machine can conduct arc striking welding only after the auto-darkening controller controls the auto-darkening optical gate to be darkened, and when the manual control switch is released, the auto-darkening controller firstly stops the working of the controlled electric welding machine and then controls the auto-darkening optical gate to become transparent. The equipment has the advantages that the shading process is not easily interfered by other factors, and the reliability is high.

Description

technical field [0001] The invention relates to welding equipment with a semi-automatic dimming welding mask, which belongs to the technical field of welding and protective equipment. Background technique [0002] The welding process is widely used in the industry, and the welding arc light has a great harmful effect on the welder's eyes. Welding masks are an important tool to protect welders. With the development and progress of technology, various electronic automatic dimming protective masks have appeared at home and abroad. Their principle is that the optical signal is converted into an electrical signal by a photoelectric sensor, and then the electrical signal is processed by an electronic circuit to control the dimming shutter to realize automatic dimming. However, the existing automatic darkening welding masks still have many problems in use. For example, the reaction speed of ordinary products is slow, and the price of the fast reaction speed is relatively high; A...
