The difference between IF electric welding machine and IF electric welding machine?

Mid-frequency inverter DC welding machine is the frequency (50Hz) AC converted to mid-frequency (1000Hz) DC output, time resolution than the frequency to improve the control accuracy is also improved, and the output current is not affected by changes in the secondary output circuit, high thermal efficiency, high output power, welding quality is also better. Compared with the traditional AC welding machine, inverter MF DC welding will be highly efficient, energy saving and all in one, is a very broad prospects for the development of energy-saving products, is a breakthrough in the field of resistance welding of a technological revolution.

Mid-frequency inverter spot welder advantages:

1. It is one of the high-end resistance welding machine products that are internationally respected. It adopts secondary rectifier technology, fully closed control loop and medium frequency inverter technology, compared with the traditional resistance welding machine, it has small size, high output current, small welding circuit loss, stable welding current, high power factor of the whole machine, balanced grid input, small impact on the power grid, low production cost and so on.

2. It also adopts microcomputer control, which greatly improves the stability of the welding system and the simplicity of the operation as well as the friendliness of the interface

Use: Widely used in machinery manufacturing, hardware, household electrical appliances, automobile manufacturing, aviation and aerospace and other fields.

1, the current flowing in the secondary welding circuit is DC, so the inductive reactance in the secondary circuit due to the different immersion depths in the deep welded workpiece greatly reduces the influence of the welding current.

2, three-phase balanced load, reducing the power requirements of the power supply system, power factor close to 1, no inductive component, no need to adjust the power factor.

3, to eliminate the pollution of the power supply, is the green welding, do not have to provide separate power supply can be used together with the robot welding tool control system.

4, reduce power consumption, energy saving, but also to reduce the need for cables and spend and a lot of maintenance costs.

5, the quality of the welding transformer is greatly reduced, lightweight and fast, only 1/3 of the quality and volume of the AC transformer, suitable for robotic welding systems.

6, improve the efficiency of heat input, welding transformer output is DC voltage, no inductance annoyance, pure DC without the shortcomings of over-zero, the efficiency of the heat is greatly improved

7, intelligent digital full closed-loop control, welding control current is more **, the precision of the adjustment and monitoring accuracy than the AC system is 20 times higher. Inverter and transformer can be protected.

8, increase the stability of the welding process, DC welding process friendly, welding parameters can be adapted to a wide range of secondary current can really maintain a constant current, than the AC to have a wider range of prospects for use.

9, digital control to improve the current control and measurement accuracy, welding time accuracy of milliseconds, you can control the welding time arbitrarily.

10, suitable for welding aluminum, stainless steel, copper and galvanized metal and other materials. Medium frequency inverter spot welder and the traditional frequency AC welding machine compared to the advantages

Advantages of the main tips: compared with the traditional frequency AC spot welder, medium frequency inverter spot welder running energy costs than the frequency AC spot welder to save nearly 1/3, suitable for automation, control of the high degree of intelligence, to adapt to a wide range of materials, in particular, can get a stable, reliable quality of the welded joints.

Compared with the traditional frequency AC spot welding machine, medium frequency welding machine running energy costs than the frequency welding machine to save nearly 1 / 3, suitable for automation, high degree of control intelligence, to adapt to a wide range of materials, in particular, can be stable, reliable quality of welded joints.

With the rapid development of the automobile industry, the safety of the automobile body structure and the use of new materials for the body of the welding process puts forward new challenges. For welding under the conditions of coated steel plate, glue coated steel plate, multi-layer plate and different material plate, the traditional frequency spot welder is difficult to meet the welding requirements, and various advanced welding processes and welding equipment, such as medium frequency inverter welder, laser welder, etc., have emerged.

In recent years, some foreign production of automotive batch of large enterprises will be medium frequency spot welding robot and servo technology spot welding robot used in car body-in-white welding line. Especially in Europe, the use of medium frequency spot welding robot has accounted for 40%, and expanded to aluminum alloy car body spot welding operations. In the domestic medium-frequency spot welding machine in the major automobile factories have also been more and more widely used, such as FAW-Volkswagen, Chery Automobile, Beijing Hyundai, Dongfeng Nissan and other manufacturers have been used in the medium-frequency welding machine in the automatic line welding or manual spot welding.

Compared with the traditional industrial frequency welding machine, the biggest advantage of the intermediate frequency welding machine is good DC polarity, good welding quality. SMD-40 MF spot welder in Chery Automobile A5 white body production line as an example to illustrate the MF spot welder good welding.
