Are you interested in digital welding machine?

Let’s start our knowledge time - Digital Welding Machine!

Well compared with traditional welding machine, 

it has the following characteristics:

1. Multi-functional

The function of the traditional welding machine is realized by many analog and logic circuits. 

Every additional function requires many components. 

To have more than two functions requires many circuit boards. 

This will not only greatly increase the cost of the welding machine, but also the performance 

and reliability of the welding machine will drop sharply with the increase of components. 

Therefore, it is difficult for the traditional welding machine to integrate multiple welding functions Into a welding machine.

The function of digital welding machine is realized by software. 

To increase the function of digital welding machine, you only need to change the software. 

Each function module is independent of each other. Adding new functions does not affect the original function and performance at all. 

Therefore, the function of digital welding machine can be very rich.

2. The product has Good Consistency, Stable and Reliable Performance.

The composition of traditional welding machine determines that its performance depends entirely on the parameters of each component. 

The inconsistency of component parameters directly leads to the inconsistency of welding machine performance, 

and the components produced by any manufacturer can not guarantee that their parameters are completely consistent, 

so it often occurs that one welder of the same brand is different from another. 

In addition, the parameters of the components will change with the temperature, humidity and other environmental changes, 

so the performance of the welding machine will be good and bad.

The characteristic of digital circuit is not sensitive to the change of component parameters. 

For example, the performance of welding machine will not be affected when an input or output resistance changes from 1K to 10K. 

So the consistency and stability of digital welding machine is better than traditional welding machine.

3. High Reliability

The welding machine adopts high-speed DSP control, which can detect and correct the main transformer magnetic bias in time, 

effectively avoid the damage of the welding machine due to the main transformer magnetic bias, and greatly improve its reliability; 

it has the function of under voltage, over voltage and overheating protection; IGBT is isolated from the air duct, so as to avoid rain, 

dust and other damage to the welding machine. In addition, due to the use of digital technology, 

greatly reducing the number of components, improve the reliability of the circuit.

4. High Control Accuracy

The accuracy of simulation control is usually determined by the error caused by the component parameter value 

and the error caused by the non ideal characteristic parameter of the operational amplifier, so it is difficult to achieve high-precision control. 

The accuracy of digital control is only related to the quantization error of analog to digital conversion 

and the limited word length of the system, so the digital control can obtain high precision.

5. Fast Dynamic Response

Most of the new digital welding machines adopt high frequency soft switching technology, 

which greatly improves the dynamic speed of the welding machine.

6. Excellent Welding Performance

For how to improve the welding performance, experts at home and abroad have done a lot of work 

and put forward many excellent mathematical control models, 

but these complex mathematical models are difficult to realize on the traditional analog welding machine, 

because it requires a very complex circuit, so it has been in the theoretical stage for a long time. 

The emergence of digital welding machine makes these mathematical models easy to realize on the welding machine.

7. Authoritative Database of Welding Experts

The application of digital technology makes welding machine become an intelligent equipment, 

which can have database function like computer, and can store the experience of many welding experts in the database, 

so that ordinary welders can easily weld out the welding level of experts. 

Especially some advanced welding methods, there are many parameters to adjust. 

If it is difficult for users to match so many parameters, 

the expert database has become the most outstanding advantage of digital welding machine.

8. Network and Automatic Welding

With the development of network and automation technology, 

more and more enterprises require that all kinds of equipment can be connected into a network, 

which can be centralized monitoring and control to realize automatic operation. 

In the past two years, the trend of using robots to replace manual welding has developed rapidly. 

Only digital welding machine can be competent for this kind of application.
