Description

Technical Field

[0001] The utility model relates to the technical field of capacitor welding machines, in particular to an electric fusion welding machine which is convenient for connecting a plug. Background Art

[0002] An electric welding machine is actually a transformer with a falling external characteristic, which converts 220V and 380V AC into low-voltage DC. Electric welding machines can generally be divided into two types according to the type of input power supply: one is AC power supply; the other is DC power supply. A DC welding machine can be said to be a high-power rectifier, which is divided into positive and negative poles. When AC power is input, it is transformed by the transformer, rectified by the rectifier, and then input into a power supply with a falling external characteristic. The input end will produce a huge voltage change when it is connected and disconnected. The two poles will ignite an arc when they are short-circuited instantly, and the generated arc is used to melt the welding rod and welding material, and then cool them down to achieve the purpose of combining them. The welding transformer has its own characteristics. The external characteristic is the characteristic that the voltage drops sharply after the welding rod is ignited, but the existing electric fusion welding machine has some shortcomings, such as:
