Many people look at the price of the automatic flash butt welding machine and think, it’s so expensive, let’s see if it’s worth it.

When the medium frequency spot welding machine is not connected to water, the electrodes are often worn during welding. What should we do? The controller can automatically increase the current. Let’s see how to operate it.

The variable frequency spot welding machine is actually between the industrial frequency spot welding machine and the medium frequency spot welding machine. It takes into account the advantages and avoids some disadvantages. The price is also more reasonable. It is a good choice. What about its waveform? Click to see the visual diagram.

There are some differences between the variable frequency spot welding machine and the intermediate frequency spot welding machine. The variable frequency spot welding machine is composed of an intermediate frequency controller and a welding resistor transformer, while the intermediate frequency spot welding machine is composed of an intermediate frequency controller + an intermediate frequency transformer. Some unscrupulous dealers write variable frequency as intermediate frequency, which makes people worried. What is the controller principle of the variable frequency spot welding machine? Let’s take a look together

The quality of resistance spot welding machines, butt welding machines, projection welding machines, and seam welding machines on the market varies from good to bad. What is the simplest and core method to distinguish them? Let’s take a look with the editor

Master, tell you what is the load endurance rate (duty load rate) of resistance spot welding machines, butt welding machines, seam welding machines, and projection welding machines? It’s different from what’s on the market. Come take a look with me.

Spot welding machines and butt welding machines are becoming more and more homogeneous. Only by maintaining specialization can we better cut out the market.

There are various small medium frequency spot welding machines. Some people like the mobile facade type, and some like the mini split type. In fact, the functions are the same, but they are adjusted in terms of humanization. Today I will talk about a case of welding by a mobile small medium frequency spot welding machine.

Conventional pneumatic spot welding and projection welding machine, but saw the craftsman using strange welding methods, what is it like? Let’s take a look with the editor of Xinxing Welding
