Causes and prevention methods of arc periodic fluctuation of CO2 welding defects

Cause of occurrence ① Uneven wire feeding ② Conductive mouth is not suitable for slipping, whether the friction resistance of the guide tube is too large ③ The primary input voltage changes greatly Check items and their elimination methods ① Whether the welding wire pan rotates smoothly, whether the wire feeding wheel slides, and whether the friction resistance of the guide tube is too large ② Whether the size of the conductive nozzle is appropriate, whether the conductive nozzle is worn too much ③ Whether the power transformer capacity is enough, and whether there is too much load nearby (resistance spot welder, etc.)铜焊丝,Copper Welding Rods,铝焊丝,aluminium welding wire,镍焊条,Nickel electrode,药皮焊条,Flux Coated Brazing Welding Rods
