Why was the old welder eliminated?

The first is that the cost is too high and the price is expensive. In the past, electric welding machines were made of silicon steel sheets, iron wires and flat copper insulated wires, but now the price of metal materials is high. Secondly, it is too heavy to transport and handle Chen Ben. Third, because the old welding machine is relatively inefficient, the heat generation is also large.

High energy consumption, so it was eliminated. Not all of them were eliminated. Some have been eliminated by BX3, and one should forget whether it is BX6 or not.

Judging from the appearance first, whether the electrified cooling fan rotates, whether the wires are damaged, etc. Then judge whether the no-load voltage is normal and whether there is pulse in inverter welding; Whether the voltage and current are stable during welding, whether the voltage and current are adjustable, and whether the wire feeding is normal.

It is the purpose of melting the solder and the welded material on the electrode by using the high-temperature arc generated by the instantaneous short circuit of the positive and negative electrodes, so that the contacted materials are combined together. Its structure is very simple, it is a high-power transformer. Welding machines can be generally divided into two types according to the types of output power, one is AC power supply and the other is DC power supply. They use the principle of inductance, which will produce a huge voltage change when it is turned on and off, and use the high-voltage arc generated when the positive and negative electrodes are short-circuited instantly to melt the solder on the electrode, thus achieving the purpose of atomic bonding.
