The electric welding machine uses the high-temperature electric arc generated by the momentary short circuit of the positive and negative poles to melt the solder on the welding rod and the material to be welded, with the purpose of combining the contact objects. Its structure is very simple; it is just a high-power transformer.
The MIG welding machine, fully known as the CO2 shielded welding machine, is a highly efficient and multi-functional welding equipment. The input voltage varies according to the power size. Low-power models usually use 220V AC power, while high-power models use 380V AC power. The output voltage range is usually set between 12 and 36V, suitable for different types of welding requirements. The MIG welding machine is mainly used for welding low-carbon steel and low-alloy high-strength steel. It features high productivity and excellent welding quality, and is suitable for welding thin plates and medium-thick plates.
An argon arc welding machine is a device that uses argon arc welding and adopts the arc starting method of high-voltage breakdown. Argon arc welding, also known as tungsten inert gas shielded arc welding, refers to a welding method that uses industrial tungsten or active tungsten as the non-melting electrode and inert gas (argon) as the protection. It is abbreviated as TIG. It is generally used for the welding of thin plates ranging from 6 to 10 meters and the bottom sealing welding of single-sided welding and double-sided forming of thick plates. The commonly used welding machines include the domestic YC-150 type manual tungsten inert gas welding machine.
The plasma cutting machine heats and ionizes ionized gas to generate plasma, and then cuts the workpiece under the action of the heat and kinetic energy of the plasma. Plasma cutting machines are mainly used for processing metal materials and can cut thick metal materials such as stainless steel and iron plates at a relatively high speed.
