An electric welding machine is actually a transformer with a decreasing external characteristic, which converts 220V and 380V AC power into low-voltage DC power. Welding machines can generally be divided into two types according to the type of output power source, one is AC power source; One type is direct current. A DC welding machine can also be said to be a high-power rectifier. It is divided into positive and negative poles. When AC power is input, it is transformed by a transformer and rectified by the rectifier, and then outputs a power supply with a decreasing external characteristic. The output terminal will produce a huge voltage change when it is turned on and off. When the two poles are short circuited in an instant, the arc is ignited, and the generated arc is used to melt the welding electrode and material. After cooling, it achieves the purpose of combining them. Welding transformers have their own characteristics, and the external characteristic is the sharp drop in voltage after the welding rod ignites

The main component of the welding machine is a step-down transformer, and the two ends of the secondary coil are the workpiece to be welded and the welding rod. During operation, the arc is ignited, and the welding rod is fused into the gap of the workpiece at high temperatures of the arc. Due to the unique characteristics of the iron core in welding transformers, there is a sharp drop in voltage, which occurs after the welding rod ignites; When the welding rod is stuck and short circuited, the voltage drops sharply.

During welding operations, although the current in the circuit is equal everywhere, due to the different resistances at different locations, the resistance at non fixed contacts is high (this resistance is called contact resistance). According to the law of thermal effect of current (also known as Joule's law), Q=IRt, it can be known that when the current is equal, the higher the resistance at the part where the resistance is greater, the higher the heat generation. Therefore, during welding, the contact resistance at the contact point of the welding rod, that is, the contact point of the connected metal body, is higher, and the electric heat generated at this part is naturally greater. In addition, the welding rod is an alloy with a lower melting point, which is naturally easy to melt. The melted alloy welding rod core is bonded to the welded object, and after cooling, the welded object is bonded together.

Generally, the panel of a DC inverter welding machine is equipped with an output DC current adjustment knob. The inverter DC welding machine first performs bridge rectification and filtering on single-phase AC 220V voltage or three-phase AC 380V voltage, and then supplies power switching devices for inverter processing.

Introduction to Shanghai Chuanqi Electromechanical Equipment Co., Ltd

Shanghai Chuanqi Electromechanical Equipment Co., Ltd. was established in 2005 in an office of less than 20 square meters on Dongfang Road in Pudong New Area. At the beginning of its establishment, the company positioned itself as providing international leading electromechanical equipment products such as Europe and America to domestic customers. After years of efforts, the company now integrates agency sales, scheme design, and after-sales service, fully providing services to domestic customers.

After years of practice and experience accumulation, we have established good and long-term cooperative relationships with a large number of overseas brand manufacturers and suppliers such as Europe and America. In addition, our company's one-stop supply service system integrates procurement, scheme design, logistics, and after-sales service. We think what customers think and respond to their urgent needs, truly achieving "cost reduction and profit maximization" for customers.
