Do you know the main features of IF inverter spot welding machine?

Intermediate frequency inverter spot welding machine has excellent performance, suitable for welding thin metal parts with high thermal conductivity and fine workpieces. The intermediate frequency inverter welding machine inverts the 50HZ AC power rectification filter to an intermediate frequency square wave of 800HZ to 2000HZ. After the intermediate frequency transformer (the size and weight of the transformer is only about half of the traditional welding transformer), it is reduced to low voltage alternating current and then passed through a single-phase full wave. The rectification is low-voltage direct current, and the workpiece is welded by an integrated spot welding clamp or a fixed spot welder.

What is the difference between IF spot welding machine and power frequency AC welding machine

No matter in the fields of machinery industry or technology industry, China is achieving perfect improvement and rapid development. Therefore, various types of machines have also been improved and further updated several times to make them more intelligent and efficient. On the basis of ensuring quality and efficiency, the projection welding machine also guarantees the impact on the environment and becomes an excellent machine with low pollution. Below I will tell you the difference between the characteristics of the intermediate frequency spot welding machine and the power frequency AC welding machine.

What benefits does the intermediate frequency point convex welding machine bring to the enterprise?

What is the direct benefit brought by the intermediate frequency spot welding machine to the enterprise? Where many people find it difficult to consider, it is often simple and clear, and it is easy to be ignored by everyone, so let ’s take a look at how to save electricity. as follows:

What are the outstanding advantages of intermediate frequency spot welders

There are many types of spot welders, so what advantages does it have in the market for intermediate frequency spot welders? First, the forward, welding effect, inverter DC spot welding machine time adjustment resolution can reach 0.25ms (4kHz inverter frequency), high control accuracy. The response speed of the feedback control of the inverter welding machine is significantly faster, and the output stability is good. The output current of the inverter DC spot welding machine is pulsating DC, and it is continuous DC output under the action of the loop inductance. It has high thermal efficiency and stable welding heat input.

Problems encountered when spot welding machines are welding copper and aluminum plates

Problems encountered when spot welders weld copper and aluminum plates: When the workpiece and the electrode are constant, the resistance of the workpiece depends on its resistivity. Therefore, resistivity is an important property of the material being welded. High-resistivity metals are conductive Metals with low electrical resistivity have good electrical conductivity. Therefore, it is difficult to produce heat when spot welding stainless steel, and it is difficult to dissipate heat. It is difficult to produce heat when spot welding aluminum alloy. Million amps). Resistivity depends not only on the type of metal, but also on the state of the metal, processing method, and temperature.
