1000HZ spot welding machine or 50HZ spot welding machine which Sunar is better?

1000hz is DC, 50hz is AC spot welding machine, it should be said that the current of DC Sunar spot welding machine is more stable, and the current of AC spot welding machine is in the form of sine wave, which fluctuates.

It is better to use 50Hz for ordinary thin steel plates, and it is better for Sooner 1000Hz DC welding machine to weld aluminum plates.

The intermediate frequency resistance welding spot welding machine adopts the first rectification filter, and then inverts into about 20kHz medium frequency alternating current, and then transforms the voltage rectification, because the transformer worker hole is used as the AC frequency in the medium frequency, so it is called the intermediate frequency spot welding machine.

The intermediate frequency spot welding machine is just a type of spot welding machine, not referring to which brand, just like now the new energy vehicle cannot be said to be BYD car.

The Sunar medium frequency inverter spot welder you are talking about is a medium frequency resistance spot welder.

There are many kinds of spot welding machines, including resistance spot welding machines, gas shielded welding machines, ultrasonic spot welding machines, polymer diffusion welding machines, etc., these types of spot welding machines belong to different fields, and the brands of spot welding machines are definitely not the same, each with its own differences.

Let's give you a brief breakdown:

1. Resistance spot welding machines, including intermediate frequency spot welding machines, rolling welding machines, energy storage welding machines and traditional power frequency AC spot welding machines, Sunar (sooner) has done a better job in this area, and it can be regarded as a trustworthy brand in terms of product quality and service.

2. If it is carbon dioxide gas shielded welding, it also belongs to the spot welding machine, but the principle of welding is different, and the gas shielded welding needs to be filled with welding wires.

3. If it is an ultrasonic spot welding machine, the principle is different from the principle of resistance spot welding machine, for example, the ultrasonic spot welding machine is used in the production of masks now, and the imported telsonic in this piece is doing very well, but it has little advantage in the field of metal welding.

4. There is also a polymer diffusion welding machine, and there are many manufacturers now, but there are no better brands, they are all about the same.

Generally speaking, there are really not many spot welding machine brands that can be taken out in China, and they are generally average, I feel it.

It is certain that the intermediate frequency spot welding machine is more expensive than the AC spot welding machine, after all, the things are different and the cost is not the same.

Like all goods, the product is too cheap and there is certainly no guarantee, no business is willing to lose money to serve you, Lu Xun said: things are expensive not necessarily ***, good service, but things are too cheap quality and service will not be good.

I bought Sunal's intermediate frequency spot welding machine before, bought it for 10,000 yuan, and later saw that some manufacturers sold 10,000 yuan with similar specifications, and it was not very comfortable at that time, who could be comfortable. In this way, I bought another manufacturer's intermediate frequency spot welding machine for 10,000 yuan, and then I regretted it even more, the machine is cheap, but there are a lot of problems, call them to come over to the after-sales bar, and push the three and four, not to say, think about it and get angry. In general, regardless of the quality of the machine, it is worth our consideration for the after-sales service.

I now buy daily necessities are to go to the store to buy, the goods are guaranteed, the after-sales service is very intimate, small traders and hawkers are really unreliable. Even if I spend a few hundred dollars more, I spend it comfortably.

Therefore, I suggest that you spot welding machine manufacturers, do not blindly fight for sales, we support you to have your profits, but you can not be sloppy in the quality of the equipment, and you should also pay attention to after-sales service, which is what our customers really want.
