With the development of science and technology, welding equipment has been introduced. Among them, the pulse argon arc welding machine is the most popular. The pulse argon arc welding machine is a welding method that uses pulse current to achieve the droplet transfer. It has no spatter, large penetration, and fine grains. The welding seam has high strength and is suitable for all-position welding. It can achieve stable and high-quality welding from 20 to 500 amps. The welding performance is far better than ordinary gas shielded welding machines. It is the mainstream direction of welding machine development. Together with Sichuan Pulse Argon Xiaobian arc welding machine manufacturers to understand the characteristics of the next pulse argon arc welding machine:
The function of the traditional welding machine is realized by many analog and logic circuits. Each additional function requires a lot of components. To have more than two functions, a lot of circuit boards are needed, which not only greatly increases the cost of the welding machine. Moreover, the performance and reliability of the welding machine will decrease sharply with the increase of components, so it is difficult for a traditional welding machine to integrate a variety of welding functions into one welding machine.
The function of the digital welding machine is realized by software. To increase the function of the welding machine, you only need to change its software. Each functional module is independent of each other. The addition of new functions does not affect the original function and performance at all, so the digital welding machine function can do Very rich. For example, the Nebula series welding machine has covered manual welding, DC argon arc welding, pulse argon arc welding, argon arc spot welding, gas shielded welding (CO2, MIG, MAG), pulse argon arc welding, and double pulse argon arc welding. Welding and carbon arc gouging eight welding methods. Each function has many adjustable parameters. Users can either use the system default parameters to set the welding machine very conveniently, or fine-tune the welding machine according to different welding requirements to achieve the best welding results.
2.Good product consistency and stable and reliable performance
The composition characteristics of a traditional welding machine determine its performance characteristics completely rely on the parameters of each component. The inconsistency of component parameters directly leads to the inconsistency of the welding machine performance, and the components produced by any manufacturer cannot guarantee that their parameters are completely consistent, so Frequently, one welding machine of the same brand is different from the other. In addition, the parameters of the components will change with the changes of temperature, humidity and other environments, so the performance of the welding machine will appear good and bad.
The characteristic of the digital circuit is that it is insensitive to changes in component parameters, such as an input or output resistance change from 1K to 10K will not affect the performance of the welding machine. So the consistency and stability of digital welding machine is much better than traditional welding machine.
The digital welding machine adopts high-speed DSP control, which can timely detect and correct the main transformer bias magnetism, effectively avoiding the welder's damage due to the main transformer bias magnetism, greatly improving its reliability; with under-voltage, over-voltage and over-heat protection functions; It is isolated from the air duct to prevent rain and dust from damaging the welding machine. In addition, due to the use of digital technology, the number of components is greatly reduced, and the reliability of the circuit is improved.
