The welding electrode production line is a welding rod production line with high automation, high production efficiency, stability, durability, easy operation and maintenance. The welding electrode production line is generally about 8-10 tons or 15-16 tons every 8 hours. It has the characteristics of stable structure, reasonable design, simple operation, energy saving, labor saving, convenient maintenance, feeding without stopping, continuous production, high production efficiency, uniform coating thickness, smooth, dense, stable quality and so on. The welding electrode production line can also realize the automatic production of the processes of electrode coating, transmission, grinding head, grinding tail, printing, drying and packaging. It is a good welding electrode production line in the current electrode production.
