How to recognize copper clad aluminum in electric welding machines, there are several copper clad el

The only way is to boot up. Look at the coil, look** There are copper-clad aluminum, half copper and half aluminum. There is a primary aluminium and a secondary of copper.

The purpose of the electric welding machine is to use 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, so that the contact object is combined. 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.

Generally, businesses will not deceive customers, because in order to develop in the later stage and maintain their good reputation, reputation is the most important thing for businessmen, but it is not excluded that there is such a possibility, I work in a welding machine company, and the general customer will call ** to consult, tell the machine number to find out whether it is copper or aluminum, copper and aluminum welding power is not the same when welding, it should be easier to separate, for insurance, or to the manufacturer to consult

Don't be fooled

I don't know how the first floor came up with it, and cut the line a little bit.

Although your answer on the second floor has some truth, it can't be completely discerned.

It is best to hit the manufacturer, and the manufacturer hates the manufacturer for damaging the reputation of the product.

As long as there is a machine number, you can find it. At least that's how it is in our company.

It's easy to see, scrape the wire of the transformer a little bit with a blade, and you can tell whether it's copper or aluminum. Note that it is necessary to scrape on the Yao group, and the lead Rui usually welds a piece of copper in the welding machine factory to counterfeit.

The welding machine of aluminum taps the key line of copper, which is soft and aluminum, and hard and through.

Summary. Normally, an electric welder has two copper claddings, one of which is the current output end and the other is the ground wire connection end. Some high-power welders are equipped with a third copper ladle to regulate the voltage and current during the welding process.

Normally, the welding machine has two copper ladles, one of which is the dust end of the current output key, and the other is the ground connection end. Some high-power welders are equipped with a third copper ladle to regulate the voltage and current during the welding process.

Can you elaborate on that a little bit more?

The output power of an electric welding machine is usually composed of a combination of a copper ladle and a power wire. Copper ladles are usually composed of some iron cores wound with copper wires, which can convert low clear voltage and high current into high voltage and low current to achieve arc welding during operation. The average welder usually has only one copper cladd, but some high-end welders may have two or more copper ladles in order to achieve more efficient welding capabilities.

The details and structure of the copper ladle of different types of welding machines may be slightly different, but the basic function of their pies is the same, which is to convert low voltage to high voltage to create an arc to complete the welding beat job.

Summary. Welding machines usually have two copper cladding.

Welding machines usually have two copper cladding.

I'm sorry I don't understand, but can you elaborate on that?

The welding machine usually has two copper packs, one is the input power supply copper shock orange pack, which is mainly used to connect the AC power supply and convert it into the required DC field shooting power. The other is the output current copper ladle, which is mainly used to adjust the current intensity and stabilize the output, so as to meet the current requirements of different welding needs. For some high-end welders, they may also have a third copper ladle that is used to connect the cable welding gun and transfer electrical energy for welding operations.

In short, the number and use of copper ladles vary depending on the type and brand of welding machine, and different welding machines are suitable for different work needs and use occasions.

Summary. Hello, I'm glad to be able to your question, according to the situation you described, at present, the electrical and thermal conductivity of aluminum is worse than that of copper, and the transformer is more likely to heat up during the working process, which affects the service life, therefore, the welding machine that is often used is best to use copper core.

I suggest you refer to it, hopefully, I hope it can help you, I wish you a happy life, and you can consult me if you have any questions, smile

What is the difference between aluminum welding and brazing machine.

Hello, I'm glad to be able to your question, according to the situation you described, at present, the electrical and thermal conductivity of aluminum is worse than that of copper, and the transformer is more likely to heat up during the working process, which affects the service life, therefore, it is best to use copper core for the welding machine that often uses the royal brother. I suggest you refer to it, hope, I hope to be able to help you, I wish you a happy life, and you can consult me if you have any questions, smile

Can brazing be used to weld the varnel?

That's too slow, isn't it?

Sorry, I'll answer you right away.

Hello At present, it is generally possible to weld aluminum, which is supported.

Do you want to change the welding head?

Hello, in general, some models are supported, and there is no need to change the welding head.

Oh thanks. However, some models are not supported and need to be replaced, depending on what model of equipment it is.

The electrode hand arc welding machine is not recommended to use copper-clad aluminum welding wire instead of copper national standard welding wire, and the comparison between copper-clad aluminum welding wire and copper national standard welding wire is as follows:

1: Increase the labor intensity of welding personnel and reduce the welding quality. The conductivity of copper is higher than that of copper-clad aluminum wire, and the same welding current uses copper-clad aluminum welding wire to require a thicker cable diameter, and the weight is larger to cause wrist fatigue of welding personnel, aggravate the labor intensity of welding personnel, and people's physical endurance is limited, and long-term welding will directly lead to a decline in welding quality.

2: Increase the danger of the welding process. Even if the copper-clad aluminum resistance is greater than the copper national standard welding wire, long-term high-current welding will cause the aluminum wire resistance to heat too much and burn the welding wire, if welded in the metal container, the welding wire, the ground wire direct short circuit will cause the welding machine to burn out, lead to disasters, and cause electric shock to the welding personnel to cause accidents.

To sum up, the soldering wire must use the national standard copper multi-strand copper core soldering wire. It cannot be replaced by copper-clad aluminum solder wire.

Long-term high-current welding is a day of quasi-waste, and the copper-clad aluminum is too hard, and the welding handle is not flexible.

It is mainly reflected in the service life and power problems.

It is recommended to use rare earth aluminum alloy welding wire, which can replace the traditional copper core welding wire, and the price is cheap.

1. Aluminum alloy cable has the best economy, compared with the same copper rubber sheathed cable, it is about 50% of the copper rubber sheathed cable.

2. High elongation, toughness and easy bending.

3. The service life is higher than that of copper rubber sheathed cables.

4. Light specific gravity.

5. Easy to construct.

The rare earth aluminum alloy welding wire of the Fengyan brand I use is on a treasure.

According to the structure and size of the base metal, copper-aluminum welding can be roughly divided into the following welding methods: Viadin ALCU-Q303 copper-aluminum welding rod solves copper-aluminum welding Description: a copper-aluminum welding wire with self-brazing fluoride agent, in the process of welding, because there is no need to use any welding powder and flux, it is favored by the operator, in the case of the temperature of the base metal reaching 400 degrees, the end of the flame is slightly burned with the welding wire, and the molten welding wire will flow under the action of the powder.

Because of its very good fluidity, it is especially used in the refrigeration industry, such as the socketing of copper and aluminum tubes, and the socketing of aluminum tubes and aluminum tubes. In addition, in the transformer industry, the lap of copper and aluminum conductor bars, corner joints are also used a lot, how to make the connected conductive bars can work in a high-voltage and high-current environment, the compactness of the welding layer is particularly important.

Method 2: M51+M51-F low-temperature copper-aluminum electrode, solve low-temperature copper-aluminum welding at a temperature of 179 degrees.

Description: It belongs to low-temperature brazing copper and aluminum welding, for particularly thin, and even some exaggerated thin cases, it is most suitable to use this kind of welding, but field experience proves that the welded product must have a welding angle, if the welding angle is not good, the welding effect will be discounted, because the principle of this copper and aluminum welding wire is completely formed by the heat conduction of the base metal, and the angle is not good to burn the welding wire and flux, which will lead to welding failure. It is mainly used in irregular welding, which is best to be formed at one time, as well as the welding of copper and aluminum enameled wires, which is especially used in the lead wires on electronic products and motor products.

Guo Yan talked very hard about the meat and degraded it into Boxiong, and gave 7 houses to Langben, three pigs, and a maid, and a ban on marriage and lacquer practice.

Accounts and mines.

Of course, yes, but the welding materials and welding precautions have changed.

1. The low-temperature M51 with M51-F welding wire is operated in the environment of 179 degrees at a working temperature, which has a good affinity for the welding materials of the system, and is mostly used for welding with particularly strict requirements for deformation control or particularly thin conditions.

2. WE53 low-temperature aluminum electrode for the welding of 7 series of aluminum alloys, the welding working temperature is 380-400 degrees, the advantage is that there is no need to assist any flux welding when welding, so as to prevent some flux residue in the welding process, and the welding strength is very high, which can solve the welding of 3 series aluminum alloy and castings, or die castings.

3. Q303 low-temperature aluminum welding wire also reflects some special advantages for the weldability of aluminum alloy, which is the narrow gap welding with a not very good angle.
