What Is an Arc Welder?
Arc welding machine is divided into electrode arc welding machine, submerged arc welding machine and gas shielded welding machine according to the welding method; it can be divided into two categories: melting electrode and non-melting electrode according to the type of electrode; manual arc can be divided according to the operation method Welders, semi-automatic and automatic welding machines: According to the power source of arc welding, it can be divided into AC arc welding machine, DC arc welding machine, pulse arc welding machine and inverter arc welding machine.

- The electric welding machine uses the high temperature arc generated by the positive and negative poles in an instant short circuit to melt the solder and the material to be welded on the welding electrode to achieve the purpose of combining them.
- Electric welding machine is actually a transformer with external characteristics. It converts 220V and 380V AC power into low-voltage DC power. Electric welding machines are generally divided into two types according to the type of output power. One is AC power;
- One is direct current. The DC welding machine can also be said to be a high-power rectifier, divided into positive and negative poles. When AC power is input, it is rectified by the rectifier after being transformed by the transformer, and then outputs a power source with a falling external characteristic. The output terminal is connected and disconnected. There will be a huge voltage change when the two poles ignite the arc when the short circuit occurs. The generated arc is used to melt the welding electrode and the welding material. After cooling, the purpose of combining them is achieved.
- Welding transformers have their own characteristics. The external characteristic is the characteristic that the voltage drops sharply after the electrode is ignited.
- Because welding is flexible, simple, convenient, solid and reliable, the advantages of welding and even the same strength as the base metal are widely used in various industrial fields, such as aerospace, ships, automobiles, containers, etc.
