The past two decades, with digital, automatic counting machine technology, mechanical design technology development, and improve product quality requirements, Mig Welding Wires, aesthetics, such as greater attention. Especially after the 2008 financial crisis, with the increase of labor costs in China, and the health workers attention and improve production efficiency, so in the modern industrial production, more and more welding production process began to use the automatic welding machine. The automatic welding machine (Automatic welding Special equipment) is specifically designed for a particular workpiece and a certain shape of the welded joints and welding automation equipment. Electrical control, pneumatic control, hydraulic control technology, electric motor, pneumatic actuator, hydraulic actuator rotating or moving relative motion of the workpiece weld torch, to automatically complete the Carbon Steel Welding Electrodeof welded joints.
