A welding wire reel is a tool used to store and collect welding wire. Welding wire is a wire welding material used as a filler metal or as a conductive wire at the same time. The production and use of welding wire cannot be separated from the welding wire reel, because the outer surface of the welding wire is prone to rust, which requires very strict management for it. Therefore, it can be seen that the role of the welding wire reel should not be underestimated, and its price is affordable, can be accepted by the market public, can better preserve the product, and the metal welding wire reel is more environmentally friendly, will not pollute the environment, and can be recycled . Therefore, it is widely praised by the public. And due to the wide application of welding wire, people also have a great demand for welding wire reels. One-piece plastic or metal wire reel is commonly used in gas metal arc welding. The welder installs the welding wire reel on the gas-shielded welding wire feeder, and the welding wire is fed into the welding torch for welding. This type of welding wire reel can meet the needs of welding. With the rapid development of economy and society, welding technology is widely used in various fields. No matter what industry it is, a large amount of welding wire is needed in the welding process operation, and the welding wire is generally installed in a wire reel. Therefore, the demand for welding wire reels is becoming more and more extensive, especially in advanced manufacturing industries such as machinery, construction, and electric power.
