The difference between medium frequency electric welding machine and power frequency electric weldin

Power frequency refers to the working frequency between 50 and 60Hz....The working frequency of the intermediate frequency is 800 to 1000Hz....That is to say, the IF does more work than the IF frequency....The operating frequency is different, so....The power is naturally different....The welding machine is a riser, with low electric high voltage.

Whether there is an inverter or not, the frequency is different.

1. The welding current of the intermediate frequency welding machine is close to complete DC, because there is no obvious peak current, the nugget size is steadily expanded, there is almost no spatter, and the welding quality is stable and the thermal efficiency is high. Compared with the power frequency welding machine, the welding current of the medium frequency inverter welding machine can be reduced by 40%, and the service life of the electrode is greatly extended.

2. The transformer of the intermediate frequency welding machine is small in weight and size, and the input power is low, which is convenient for the use of transformer type welding tongs. When applied to robot spot welding operations, the load of the robot can be reduced, while the power frequency welding machine is used in automatic lines, and the robot with a stronger load capacity is required.

3. The response speed of the intermediate frequency spot welding machine is only 1 20 of the power frequency welding machine, and the current can reach the set value faster, analyze the parameters more accurately, and the welding quality control is more accurate.

4. The three-phase load of the intermediate frequency spot welding machine is balanced, the power factor is high (left and right), and the energy saving is energy-saving. However, it is difficult to ensure the balance between phase voltages when working in two-phase power frequency welding machine, and the power factor is low (left and right), while it is difficult to achieve constant current output in three-phase power frequency welding machine.

5. The intermediate frequency spot welding machine is suitable for the welding of a variety of materials and dissimilar metals, such as aluminum alloy, stainless steel, high-strength steel plate and other materials. In addition, for the welding of galvanized sheet and ordinary multi-layer sheet, the welding quality is much higher than that of the power frequency welding machine. The power frequency welding machine is only suitable for materials with good welding performance, such as mild steel plates.

The AC power supply of conventional welding transformer is 50Hz-60Hz of mains, while the power supply of intermediate frequency inverter spot welding machine is 20-40 times higher than that of traditional output 1KHz 2KHz frequency optional, 12-bit AD sampling, constant current, constant pulse width, constant voltage, constant power, closed-loop mode PID tracking setting. The fluctuation of the power grid has little impact on the welding quality, the welding accuracy is high, and the consistency is good, while the power frequency AC welding machine is a two-phase alternating current input, the current stability is not good, and the impact on the power grid is relatively large.

Hello, I am happy to serve you and give you the following answers: Generally speaking, the frequency of the electric welding machine is generally 50-60hz in the mountains. If something goes wrong, you can take the following steps to fix it:

1.Check whether the power supply voltage meets the requirements, if not, you can adjust the power supply voltage; 2.Check the circuit of the welding machine to make sure that the circuit is connected correctly; 3.

Check the wiring of the welding machine to make sure that the wiring is correct; 4.Check the power supply of the welding machine to make sure the power supply is normal; 5.Check the controller of the welding machine to make sure that the controller is normal and hungry; 6.

Check the power supply voltage of the welding machine to ensure that the voltage is normal; 7.Check the power frequency of the welding machine to make sure the frequency is normal. Personal Tips:

When using an electric welding machine, it is necessary to ensure that the power supply voltage, circuit connection, wiring, power supply, controller, voltage, and frequency are all normal to ensure the quality of welding.

Frequency conversion and medium frequency spot welding machine that current big pro, hello! The current of the inverter welding machine is larger. Medium frequency spot welding machine, the output is direct current, direct current is not affected by the secondary circuit, the output current is stable, it can be seen from the waveform diagram is a DC square wave, because the intermediate frequency welding machine through IGBT frequency conversion, can give the transformer power supply to 1000 Hz, the output current is large, strong penetration and other characteristics, the controller also subdivides the welding time into 1 millisecond unit.

The deformation of welded workpieces is generally divided into, thermal deformation and deformation of welded workpieces, as well as fusion deformation of spot welding solder joints. Anjia welding engineers will adjust the appropriate pressure and welding process parameters according to the customer's welding process requirements, which can avoid the deformation of the welded workpiece! Hope it helps!

Difference: The current is different.

Welding machine: It is the purpose of using the high-temperature arc generated by the positive and negative electrodes in an instantaneous short circuit to melt the solder and the welded material on the electrode and combine the contacts. Its structure is very simple, it is a high-power transformer.

Welding machines can generally be divided into two types according to the type of output power supply, one is AC power supply and the other is direct current. They use the principle of inductance, the amount of inductance will produce a huge voltage change when it is turned on and off, and the high-voltage arc generated by the positive and negative poles in the instantaneous short circuit is used to melt the solder on the electrode to make them achieve the purpose of atomic bonding.

The welding machine working site should be kept dry and well ventilated. According to the technical condition of the workpiece, a reasonable welding process (welding rod, welding current and duty cycle) should be selected, and the ruler should not be allowed to use overload, and the no-load power failure device should be used as much as possible. In load welding, the temperature rise of the welding machine should not exceed 601 zhang for grade A and 80 zhang for grade B, otherwise it should be stopped and cooled down before welding.

In welding, it is not allowed to adjust the current, and the current of the welding machine must be adjusted by using the handle when the welding is stopped, and it must not be too fast and too violent, so as not to damage the regulator.

Electric welding refers to the process of using an electric arc to heat and melt metals so that they are welded together. The electric welding machine is the equipment that realizes the electric welding operation.

The specific differences are as follows:

1.Definition: Electric welding is a process method in which metal is welded by punching the arc; An electric welding machine is a device that provides the required electrical energy and control functions during the welding process.

2.Function: The welding machine is used to generate the arc and provide the required scattered current, voltage and control parameter guess to support the welding process; Whereas, electric welding is the actual welding process that uses the electric arc generated by the electric welding machine to melt and join the metal.

3.Components: The welding machine is usually composed of a power supply part (including a transformer, rectifier, etc.), an arc stability control part and an output interface; And the electric welding itself only needs the arc provided by the electric welding machine and the corresponding welding joints.

In summary, the welder is a key piece of equipment in the welding process, which provides the electrical energy and control parameters to generate the arc and support the welding process. Electric welding, on the other hand, is a welding process in which metals are heated to a molten state and joined together by using an electric arc provided by an electric welding machine.
