I went to buy a spot welder, I wanted to communicate, but someone else recommended me a mid frequenc

1) The welding control current of the intermediate frequency welding machine is more accurate: the inverter system is almost not affected by the power supply system, and the welding current accuracy can still be controlled at 2 even if the network voltage fluctuates by 15; Independent of the shape of the workpiece and the material of the workpiece (no loss of inductance); The adjustment and monitoring accuracy is 20 times higher than that of AC systems.

2) Stable output of welding power supply of intermediate frequency welding machine: using welding DC process, the current output is more stable than the traditional alternating current

3) The digital control of the intermediate frequency welding machine further improves the current control and measurement accuracy.

4) The welding time accuracy of the intermediate frequency welding machine is milliseconds, and the welding time can be controlled arbitrarily.

5) The economic benefits of the intermediate frequency welding machine are good. The three-phase load balancing of the intermediate frequency spot welder, low input, no grid transition process, and low power consumption.

6) The range of welding conditions of the intermediate frequency welding machine is expandedAccording to the spot welding regulations, the diameter of the weld nugget within the stable welding range is 4t (t is the thickness of the plate). After testing, in the case of spot welding of 100 welding joints in single-phase AC welding machine, 129 welding joints in single-phase rectifier welding machine and 241 welding joints in intermediate frequency welding machine; Similarly, for coated steel plates, the single-phase AC welder has 110 welding joints, and the intermediate frequency welding machine has 355 welding joints.

7) Three-phase electric balance input, no impact on the power grid, stable welding quality, high consistency of welding parts, about 35% less power than traditional power frequency welding machine.

8) The output of the intermediate frequency inverter spot welding machine is medium frequency direct current, the welding strength is higher than that of the traditional AC welding machine, and the life of the welding electrode is more than doubled, which is the current international advanced resistance welding equipment.

AC is alternating current.

The mid-frequency is direct current.

The advantages of direct current compared with alternating current are: more accurate current output, energy saving, stable current output, and better efficiency.

In addition, it is aimed at a wider range of welding.

Hello! If you need to buy, you can search Guangzhou WSP on the Internet, consult customer service, generally speaking, manufacturers are according to the products you need to spot weld to recommend you the right product, and the difference between AC and intermediate frequency is that intermediate frequency is the frequency of the spot welding machine, and the frequency has low frequency, medium frequency, and high frequency. AC speaks of current, which are two completely different ones.

And why do you recommend intermediate frequency, manufacturers generally recommend you according to your products, which can give you a detailed understanding of the role of spot welding machines.

Compared with the traditional spot welding machine equipment, the intermediate frequency welding machine has high energy saving, lower welding current and electrode pressure.

Compared with the traditional welding machine, the stability of welding electricity is incomparable with other models.

Moreover, the cost of use is low, for example, the three-phase power supply balances the input, the power factor is high, and the electrode life is much more durable than the traditional one. The main thing is that the welding efficiency is high, because the intermediate frequency can complete a high-quality solder joint in the shortest possible time, so that the production efficiency can be improved.

Why is it worth buying a medium frequency spot welding machine? Of course, we can not ignore its characteristics, only the product has its own characteristics, so as to survive in the market for a long time, today we will learn about the characteristics of Suzhou Anjia intermediate frequency spot welding machine?

1) When the nugget is formed, it is always surrounded by a plastic ring, and the molten metal is isolated from the air, and the metallurgical process is simple.

2) The heating time is short, the heat is concentrated, so the heat affected zone is small, the deformation and stress are also small, and there is usually no need to arrange the correction and heat treatment process after welding.

3) There is no need for filler metals such as welding wires and electrodes, as well as welding materials such as oxygen, acetylene, hydrogen, etc., and the welding cost is low.

4) The operation is simple, easy to realize mechanization and automation, and the labor conditions are improved.

5) High productivity, no noise and harmful gases, in mass production, can be knitted to the assembly line together with other manufacturing processes.

It is essential to prepare the intermediate frequency spot welding machine before welding, because the upper and lower electrodes often present foreign bodies, such as oil stains, etc., which requires us to often finish, maybe in life, this is an inconspicuous little thing, but maybe it is because it causes us to have problems in the safe use of the intermediate frequency spot welding machine, although the finishing operation is simple, but it must be done often. The welding machine you are talking about should also be made by Anjia!

Power-on inspection is all necessary for us in the use of intermediate frequency spot welding machine, which is an important part of the use of welding machine, sometimes electrical equipment will appear exposed, of course, our gas system may also have leakage, so we need to do a good job of inspection before use, and then ensure our own safety.

In the use of intermediate frequency spot welding machine, we will generally use the cooling water to clean the appearance of the weldment, and after accurate installation, send it between the upper and lower electrodes to exert pressure to make it touch outstanding; The two workpieces are heated by the electricity and partially melted to form a nugget; After the power is off, the pressure is insisted on, so that the nugget cools and solidifies under pressure to form a solder joint; The pressure is removed and the workpiece is removed. Spot welding technical parameters such as welding current, electrode pressure, energizing time and electrode operation surface size have a significant impact on welding quality.

Medium frequency spot welding machine (1000hz) has the following obvious advantages:

1. Welding specifications.

2. Welding quality.

Due to the frequency up to 1000Hz, the secondary current output capacity is strong, and the waveform is straight, and the range of nucleus size stability is expanded. There is almost no spatter, and the current in the primary stage of welding increases naturally, and the surface of the solder joint is ***.

3. Adaptability.

It is suitable for welding of a variety of materials, such as aluminum alloy and aluminum and other materials with fast thermal conductivity and poor weldability. For the welding of galvanized sheet and ordinary multi-layer plate, the welding quality is much higher than that of the power frequency welding machine;

4. Transformer.

The transformer size is small and the input power is low;

5. Energy utilization.

Three-phase load balancing, power factor up to above, energy saving (according to the report of General Motors of the United States, intermediate frequency spot welding saves 4 cents per welding time compared with power frequency spot welding);

6. The utilization rate of auxiliary materials has no obvious peak current and good spatter, which shortens the welding time and has a long service life of the electrode; The efficiency is higher than that of AC, especially in some high-speed seam welding.
